I have been using the Sonicare Advance A4100 power toothbrush for many years. At first, with A-Series brush heads and later with E-Series contoured brush heads. Recently, I bought the newer Sonicare e5500 model. There were a few reasons for this. More precisely, two. One: it was cheap and came with a rebate. Two: my current handle contained a Ni-Cad battery that had ceased to be.
The A4100 toothbrush worked great for me and I had no particular complaints about the A-Series brush heads either. They did require periodic cleaning, otherwise toothpaste accumulation caused an unpleasant substance to form inside the brush heads' bases and the toothbrush's handle's top part. The new Sonicare Essence e5500 uses E-Series heads and is an improvement.
Power Toothbrush: What's the Big Deal?
I got my first power toothbrush, the Sonicare Advance, at an advice of my dentist, who was concerned that I am applying too much pressure while brushing and was damaging my enamel. According to him, the power toothbrushes provided just the right amount of pressure and also cleaned better. And Sonicare was the brand he recommended. I am glad that I obliged.
Using the powered toothbrush was awkward at first. The toothpaste would splash until I learned to enclose the brush in my mouth. The vibration would feel too strong at first, even though the brush had the feature to start off at the lower power level and build up the power over 10 (or 20, do not recall) first uses.
But after a while, I could not imagine using a regular, non-powered toothbrush on a regular basis. The Sonicare seemed to clean better, provide just the right amount of pressure, massage teeth and gums and, dare I say, make my teeth stronger?
Sonicare Essence e5500
All of the above benefits apply to the new e5500. The brush is charged by placing it into an induction (no contacts) charger base. The handle has a Ni-Cad battery that is good for two weeks of traveling, if needed. The brush heads are removable and need to be changed once in 3 months.
The e5500 handle comes with a charging base, two E-Series heads, a travel case. It features a 2-minute timer and a Quadrapacer interval timer. The former stops the good vibrations after 2 minutes, so you don't have to time how long you brush. The latter splits those two minutes into 4 quarters and indicates when you need to switch from side to side and up/down.
Brush Heads: Are E-Series Heads Better Than A-Series?
I was already familiar with the improvement that the E-series brush heads of the new e5500 represent over the A-Series. In fact, the improved brush heads are a major factor why the e5500 is better than the older, so-called "Advance" design. The E-Series brushes have somewhat longer, but more slender neck, which is angled and, just as the product advertisement says, helps it reach better. Yes, to those, so-called, "hard-to-clean" areas.
The E-series heads also feel like they clean better and produce stronger vibrations than that of the A-Series. The bristles themselves have more curved arrangement, which is good.
Overall Use
The e5500 and the E-Series brush heads are overall better than the A-Series brush heads and the A4100 handle I used before. But the clean-up is a little more cumbersome. Despite having some soft material in the top part of the joint between the brush's neck and its "nut", or whatever you want to call the part that attaches to the handle, the toothpaste reliably collects in the area between the brush and the handle on each single use. A-series heads were made completely of hard plastic and they (as well as the A4100 handle) collected seemingly less stuff. Fortunately, the new brush heads and the handle are easy to rinse.
The Quadrapacer is not something I care much about since I don't feel I need it, but it is a nice-to-have feature.
Construction
The handle and the heads have solid construction. The heads feature differently-colored bands around their necks, which helps one differentiate one's brush from the others'. The handle and heads are made of plastic, which is seemingly whiter than that of the A-Series heads.
Drawbacks
After using Sonicare for somewhere about 10 years, I decided to switch to Braun Oral-B Professional Care power brush. My first Oral-B is on its way, and here is why. Although I liked the Sonicare, there always were little annoyances. The threads of the handle (and brush heads) gets gummed-up and requires cleaning once in a while, the brushes are expensive and on top of that,
Consumer Reports recently rated it at only "ok" at cleaning plaque (or whatever the empty circle means). Whereas Oral-Bs got from half-filled to filled circle. I think the Oral-B Professional Care got a full circle. But even if it was a half-circle, it is still better. Plus the brushe heads are about twice (or at least 60%) cheaper. And there is no thread to become filled with toothpaste and soap scum.
Pros: Keeps teeth and gums clean, healthy and strong; inexpensive, durable and reliable
Cons: Battery is not replaceable, needs cleaning, new brush heads every 3 months, expensive brush heads
Bottom Line
An improvement on the older Sonicare models, the Sonicare Essence e5500 is a good toothbrush. It helps me keep my teeth and gums clean, healthy and strong.

Nokia Lumia 635 vs 521
As of 12/2014, we have been using Nokia Lumia 521 phones for about 10 months. We are using them currently on the T-Mobile network. The phone were inexpensive at under $90 per phone delivered with no contract. I read that a couple of new phones were coming out to replace the 520/521. The phones in question are Nokia Lumia 635 (and a similar Lumia 630) as well as the Lumia 530.
The Lumia 635/630 phone at first blush didn't appear to be much better than the 521. The major differences include a larger screen at 4.5 inches vs 4 inches on the 521, longer battery life potentially faster 4G connectivity, faster 4-core Snapdragon 400 processor and Windows 8.1. The phone was selling for a significantly higher price than the 521. But it still has the shortcomings of the 521 had and even a new one: mainly there is no front facing camera, so using Skype is not going to be very pleasant, the camera that the phone does have, has no flash whatsoever. And the dedicated shutter release button for the camera is now gone.
The camera uses a new 4 core processor which is going to produce faster response times than the one on the 521. Do these minor improvements justify the significant increase in the street price? For a while I decided that they didn't. I planned on staying with the Nokia Lumia 521 for a while longer, maybe until Lumia 735 or 830 are available on the T-Mobile network. The Lumia 521's dedicated shutter release button for the camera is a semi-unique feature, the lack of which was a deal breaker for me.
But later I changed my stance I ordered the Lumia 635 and was impressed with it once I got it. And here is the review.

Got call from fake IRS about fraud
I got a calll today from somebody who claimed to have been from the IRS. According to him, IRS has discovered that I committed some kind of taxpayer fraud on my previous several tax returns. He gave me a case number and throughout this whole conversation I suspected that this was some kind of fraud, but he never asked me for my social security number or for money. Maybe it was because he thought I was not taking the situation seriously enough.
Throughout the conversation he maintained that I'm going to be arrested and taken into custody in the next 40 minutes to 1 hour, additionally my bank accounts and assets will be frozen, my employer notified, and I need to find a criminal attorney within the next hour.
I could hear the voices in the background like it was some kind of a call center. He maintained that in the next 40 minutes or so he was going to transfer the case, as he called it, to the sheriff's department and they would be coming to pick me up. Pretty strange considering that this would be a federal case and this is against everything I know about how the legal system works.
In addition to telling me my case number, he stated several laws and IRS regulations or whatever. It was all relatively vague but he mentioned the number for at least one of those so-called regulations.
He also stated that I could be deported, which is funny considering that I'm an American citizen. He also said that my house will be confiscated. I don't own a house. He advised me not to touch my bank accounts which made me check my bank accounts and change their passwords, just in case. I suspect that they will call me again pretending to be from the Sheriff's department or whatever and tell me that I could make these, so called, charges go away if I pay up.
While thinking how I could find a good criminal attorney and thinking about what I should take with me to jail, I decided to do some checking.
The cursory check on the internet confirmed my suspicions. Apparently this type of fraud has been increasing in frequency in the last year or so, especially against immigrants, recent or otherwise.
Just to be sure, I called IRS and after waiting for about half an hour, talked to a lady who was pretty confused about what I was referring to. Not unexpectedly, IRS doesn't deal in such kind of situations in such a way. It is unlikely they would ever call you. Most likely I would receive a letter or something to that effect.
I hope the scammers call again so that I could mess with them.
Question is how do I report these a-holes and if anything can be done to deal with them.

Apple iPhone 5 works in 2014 Honda Accord EX-L
According to my car's manual, the iPhone 5 works in USB mode in Accord models without second (touchscreen) display only. Apparently it is not true as I connected it and the music played very well.
This is in the "iPod" mode of the car's audio system. So there you have it, iPod integration works in the 9th generation Accord with iPhone 5. In models with (and presumably without) the second screen (touchscreen).

Panasonic SA-XR57 7.1-Channel Digital Receiver with HDMI - Unbelievable Sound at Insanely Low Price
After using the Panasonic SA-XR55 class D receiver for almost three years, I wanted to upgrade to something very similar (with a class-D amplifier), but with DVD-Audio playback over HDMI connection. Ideally, it would have been even better if the receiver had HDMI switching and supported Super Audio CD (SACD) over HDMI as well, but Panasonic stopped selling class D receivers (and receiver overall for that matter) and I got addicted to Class D's price, performance, low power consumption and low heat.
Even before getting my XR55, I have read on several online forums that the Panasonic XR55 (and others from the XR line, e.g. the XR57) produce amazing sound. Some people claimed that they sold their previous (very expensive) gear, because the XR55/XR57 sounded as good or almost as good. Obviously, I was a bit skeptical at first, since the XR55 sold for only $230-250. But I decided to give it a try and never regretted it.
So now, I upgraded to the Panasonic SA-XR57, which is very similar to XR55, but adds DVD-Audio playback over HDMI, dual-amping for front speakers in surround sound mode and nicer remote control. I had to buy it on eBay since new Panasonic receivers are no longer sold in the US.
What is Unusual About the XR57?
The Panasonic SA-XR57 is among so-called Class D amplifiers. The major difference with amplifiers of other types (A, B, AB, H, H , etc.) is that the Class D is digital (the others are analog) and features very high efficiency (more than 90%). This translates into lower power consumption, less heat and smaller dimensions.
The signal from your DVD or CD player (or other device that has a digital out) is kept in digital domain longer, producing less noise and other sonic benefits (which I will describe later). This is especially true with DVD-Audio over HDMI connection.
What is Panasonic SA-XR57
The Panasonic SA-XR57 is a digital home theatre receiver, available in black or silver color. It uses a Class-D digital amplifier for sever channels to provide a 7.1 configuration. The receiver is rated to deliver 100 W into 6-Ohm speakers at 0.09% THD in stereo mode. It has (among others) two optical and two coaxial digital inputs, component video switching, S-Video switching as well as a multi-channel analog input.
It also has one HDMI input and one HDMI out. Although having only one HDMI input is a bit of a limitation, it is perfectly fine for my purposes as my TV has a bunch of HDMI connections and I intend to use this receiver's HDMI input for DVD-Audio only. The receiver also does not support SACD over HDMI, but supports it over its multi-channel analog input.
Update 10/2009: I am actually using an auto-sensing HDMI switch before the receiver's HDMi input so all of my devices (HD DVD player, Blu-Ray player and a universal DVD-Audio/SACD/DVD player) can be used with the receiver without any effort.
The HDMI part of the receiver supports signal pass-through when the receiver is off and control over Viera Link (HDMI-CEC).
The receiver has sturdy speaker binding posts for all speakers (unlike other inexpensive receivers that have spring clips). In addition to 7 channels, the receiver supports a separate set of stereo speakers (A/B switching available). It also supports bi-wired/bi-amped configuration, in which you run two separate connections to each of your two front speakers (if speakers support it): one for high frequencies, another for lows.
The receiver is rated to deliver a frequency response of up to 4-88,000 Hz from all sources aside from analog multi-channel input, which is rated 4-44,000. All of them are rated at /-3 dB. The rated Signal/Noise ratio is 85 dB (103 dB IHF 66).
The receiver supports Dolby Pro Logic IIx and DTS Neo:6.
Just as the XR55, it has 2 digital optical inputs and 2 coaxial digital audio inputs, with coaxial input #1 supporting up to 192 kHz and the rest up to 96 kHz. It has 2 component video inputs instead of the XR55's three. It also has a bunch of S-Video, composite and analog audio inputs and outs with a dedicated 5.1 analog audio input for DVD-Audio, SACD or DVD players.
Getting Started
The receiver I got is in silver color. It has the same width and depth as the XR55, but is slightly heavier. The XR57 has a modern look, which I like less than the look of classical receivers. But who cares about the way it looks if it sounds good?
Connectivity was easy. The receiver has large binding posts for all speakers. I connected my Athena AS-F1 towers to front left/right channels, Athena C.5 for center, Athena S.5 surrounds and Athena P200 subwoofer to form a 5.1 configuration. I do not have enough space for the complete 7.1 setup, but once I move, I will definitely us the two S.5 rear surrounds.
The setup was relatively easy, even without the manual. I set all speakers to Large and assigned the proper device to the digital inputs I used (e.g. assigned Optical 1 to DVD).
Remote Control
The remote control that came with this receiver is better than the one that came with the XR55, even though I expected the exact same one to be supplied. It can control many functions of my DVD player (menu navigation, etc.) and is powered by 2 supplied AA batteries. It has two separate power buttons (for the receiver and the AV component currently controlled). The buttons have a good tactile feel.
In Operation
The XR57 is a 7.1-channel receiver, which can output 100 W into 6 Ohms (7 channels). It consumes only 135 W as opposed to my old Panasoinc SA-HE70, which consumed 320 W. The XR57 has no fan and it does not even get hot. At moderate listening volumes it gets only little warm. This is one of the advantages of digital amplification.
I find the receiver and its remote easy to use. The display is large and the buttons on the remote are clearly marked.
I have used the receiver mostly to listen to the music (in Stereo, 5.1 DTS Surround or converted from stereo DPL IIx/DTS Neo). I also watch movies with Dolby Digital/DTS soundtracks as well as the HD DVD with DD/DTS downconverted from DD and DTS true HD.
I have already ordered a universal Pioneer Elite DV-48AV, which plays DVD-Audio and SACD in addition to DVD video, CD-Audio, DivX and more. This player will be connected to the receiver through HDMI for the purpose of transmitting DVD-Audio in digital format over HDMI. The XR57 can pass through up to 1080i, so this is how I intend to set up the player once it arrives. And since SACD (DSD) decoding is not a part of the XR57's repertoire, I might also connect the Pioneer to the 6-channel analog inputs of the XR57.
Performance
I had to break the receiver in as at first it sounded very slightly harsh. The performance of the XR57 is nothing short of stunning, but that was expected from my experience with the XR55.
First of all, there is no noise in silent passages, whereas my older HE70 had some slight hiss. The sound is much more accurate overall, not as warm, but I would not call it bright either. Obviously, it also depends on your speakers.
All of my observations apply to a digital signal. I have not tried to critically evaluate the signal from the analog input yet. It should be a bit worse, since the signal has to be converted into the digital form before the amplification, but provided the ADC is good, the difference is going to be negligible. I believe I read that the ADCs in the XR57 are 192 kHZ/24-bit, but not entirely sure. That would provide excellent performance.
In stereo mode (no bi-wiring since the Athena F1 cannot be bi-wired), the sound is truly 3-dimentional. It is like if someone removed the barrier between me and the music. I can definitely hear more instruments in the familiar recordings, more detail (comparing to the HE70).
I listened to a variety of recordings, but mostly classical music. From classical like Ernest Bloch, Richard Wagner and John Williams to Hard Rock and Metal (Metallica, Dio). Doors, Aphex Twin, Telefon Tel Aviv, Dire Straits... All of them sound amazing. If you get this rciever and good speakers, be forewarned that you will be able to easily distinguish a poorly-recorded CD from the ones that are recorded well. For example some of my operas by Wagener sounded amazingly well, whereas the CD of preludes from his operas did not sound as good.
I heard that some people claimed that the sound was too bright for their taste. If you like very warm sound, the XR57 might be a less than optimal choice. Not for me. It does not sound too bright for me, just very accurate. I saw test results where the frequency response from the XR70 (similar hardware) was ruler-flat (20-20,000 Hz at /-0.1 dB). Obviously, you shouldn't compound the possible brightness by pairing it with bright speakers.
Same listening impressions as for the XR55 apply. On the "LA Woman" album of Doors, I could feel what kind of room some of the songs were recorded in. I could hear the small sounds I never knew were there before I got the class-D amp. In most of my recordings, I discovered something new. In fact, I could almost hear not only the horizontal position, but the distance to and the height at which each instrument was located. I know, sounds like a stretch, but it is true.
The sound, even from only two speakers, is three-dimensional and the imaging is amazing. I also tried the DPL IIx Music mode and DTS Neo Music. I liked DPL slightly better than DTS. The simulated surround gave some music even more spaciousness and was well-suited to electronic music. Things like Telefon Tel Aviv, Aphex Twin and Air sounded amazing in DPL IIx Music.
The receiver can be driven to high volumes with no signs of strain. At any volume, the dynamics are not compromised and the receiver sounds very responsive. Try as I might, I could hear no digital artifacts (in good-quality recordings). There are several modes of digital re-mastering to smooth the rough edges of MP3s and CDs that are not well-recorded. They work moderately well.
Update 10/2009: I since have gotten a lot of DVD-Audio disks and they sound amazing over the HDMI connection. There is a definite improvement over CD.
In summary, the XR57 provides amazingly good sound at very low price and I expect to save some money on my electric bill since it is so efficient. And this is also good for environment.
But
If you need more HDMI inputs and 1080p compatibility as well as decoding support for new high-res formats, you might have to look elsewhere.
Pros: Amazing sound, low power consumption, sturdy speaker connectors, features, price, HDMI
Cons: Could look better
Bottom Line
I am stunned by the sound quality of this receiver. The XR57 is insanely cheap (now on eBay), has lots of useful features and amazing sound quality. It is even good for environment. I highly recommend it!

I could hear the small sounds I never knew were there before I got the class-D amp. In most of my recordings, I discovered something new. In fact, I could almost hear not only the horizontal position, but the distance to and the height at which each instrument was located. I know, sounds like a stretch, but it is true.
The sound, even from only two speakers, is three-dimensional and the imaging is amazing. I also tried the DPL IIx Music mode and DTS Neo Music. I liked DPL slightly better than DTS. The simulated surround gave some music even more spaciousness and was well-suited to electronic music. Things like Telefon Tel Aviv, Aphex Twin and Air sounded amazing in DPL IIx Music.
The receiver can be driven to high volumes with no signs of strain. At any volume, the dynamics are not compromised and the receiver sounds very responsive. Try as I might, I could hear no digital artifacts (in good-quality recordings). There are several modes of digital re-mastering to smooth the rough edges of MP3s and CDs that are not well-recorded. They work moderately well.
Update 10/2009: I since have gotten a lot of DVD-Audio disks and they sound amazing over the HDMI connection. There is a definite improvement over CD.
In summary, the XR57 provides amazingly good sound at very low price and I expect to save some money on my electric bill since it is so efficient. And this is also good for environment.
But
If you need more HDMI inputs and 1080p compatibility as well as decoding support for new high-res formats, you might have to look elsewhere.
Pros: Amazing sound, low power consumption, sturdy speaker connectors, features, price, HDMI
Cons: Could look better
Bottom Line
I am stunned by the sound quality of this receiver. The XR57 is insanely cheap (now on eBay), has lots of useful features and amazing sound quality. It is even good for environment. I highly recommend it!
Marantz DV4001 DVD Player - 1080i Upconversion
You can never have enough DVD players. OK, maybe it is an overstatement. But DVD players are so cheap and capable now, you almost have to have an excuse not to upgrade. So naturally, when I saw the Marantz DV4001 DVD player with HDMI, upconversion up to 1080i, DivX Ultra, PAL and SECAM playback, MP3, WMA, etc., all at an insanely low price of under $85 (shipping included), I had to get it. It does not have a USB port, but a high-end name like Marantz with all these features for this price is just too hard to resist. Oh, and it looks very nice too, with its stylish front panel and at 8.8 lbs, it is built like a tank.
I have used this player with my 50-inch 1080p Hitachi plasma TV along with the Panasonic SA-XR57 receiver. Since the XR57 has one HDMI input and can play DVD-Audio (including multi-channel) when passed over HDMI, I installed a passive HDMI switch between my DVD players and the receiver. I use this HDMI switch to switch between this Marantz, the Toshiba HD-A3 HD DVD player and the DVD-Audio/SACD Pioneer Elite DV-48AV DVD player. At some point I will sell one if not two of these, since I bought and am awaiting the arrival of the Sherwood BDP-5003 Blu-Ray player ($67, shipping included, price mistake, thank you very much).
The Player
Once the player arrived, I discovered that it is really a quality piece of equipment. Not only does it weigh 8.8 lbs, it has a great-looking aluminum front panel and even the RS-232C interface, D-Bus Remote (RC-5) in/out and a direct IR input.
It only has a coaxial digital audio out (no optical) though. The remote is substantial and even has buttons to control input and volume of the amplifier. I connected the player to my receiver (the aforementioned Panasonic SA-XR57) with both a coaxial cable and an HDMI cable. Yes, the coaxial cable is redundant. But why not? For those who want to use this player for playing CD and MP3/WMA media, the DAC section has impressive specs and surely will not disappoint. I go the direct digital route as the XR57 is a fully-digital (class-D) receiver/amp.
Features
The Marantz DV4001 is a DVD player with upconversion to 480p, 720p or 1080i. It can play DivX (it is Ultra-certified), MP3 and WMA as well as display HD JPEG pictures. It will even play (and even upconvert) European PAL discs on an NTSC TV. Nice! It also plays Super VCD and VCD. And, of course, DVD-Video and CD (both in -R/+R/-RW/+RW).
Unfortunately, there is no DVD-Audio playback, SACD playback or USB port (otherwise, my Pioneer Elite would be replaced completely). The player has a coaxial digital audio out, HDMI out, component video out, S-Video and composite video out.
One more "bang for buck" variable to consider. The player comes with full 3-year parts and labor warranty. And you probably won't need it since this player feels built as a tank.
Operation
Once the player arrived, I immediately checked whether it could play European PAL discs on my non-PAL TV. It turned out it plays them and plays them well, without stuttering. It even upconverts them.
The player is medium-sized and is pretty heavy (8.8 lbs), which gives it a very solid feel. The front panel is absolutely beautiful, unlike so many recent DVD players. The front panel playback control buttons look stylish and have good tactile response. The disc tray is solid.
Again, the player is connected to my receiver and the receiver is connected to the TV using HDMI. The TV is Hitachi P50H401 50-inch plasma.
Remote Control
Most player's remote control even has buttons to control your amplifier. The buttons also glow in the dark for a while. The buttons have excellent tactile response. They do not require high effort yet have good positive feedback.
The buttons are located in reasonable order, but not as well as on the remote of my Pioneer Elite.
Picture Quality
The 1080i output over HDMI is excellent: razor sharp and clear. It does not quite have the smallest detail of the HD DVD or Blu-Ray, but it is pretty close. And I saw definite improvement over passing 480p signal from my old Philips DVP642 over component out to my TV.
The in-player 1080i upconversion of the DV-48AV is very good. It is not perfect though. You can see the stairstep artifacts, especially obvious when watch "South Park" - the diagonal lines are not smooth but resemble steps. But what can we expect from a non-high-def source?
Since I have not expected it to rival an HD DVD disc in my Toshiba HD-A3, I am very happy with the image quality. I cannot tell which is better, the upconversion of my Pioneer Elite, or this Marantz. The upconversion of the Toshiba HD-A3 is marginally better than both though.
The sound during movies is excellent as well (using coaxial digital connection as well as HDMI to my Panasonic XR57 receiver). The player also passes sound over HDMI, which is convenient. The player plays most of my MPEG and AVI computer files flawlessly. The files can be burned on a CD-R/W disc just as a regular data CD with no VCD structure needed. I say most, because although it stutters on fewer files than my Philips did, it still has issues with some files, which it refuses to play completely.
DVD-Audio and SACD
I wish it played them, but it doesn't.
Warranty
Unlike many other DVD players, which only have 90-day labor warranty, the standard Pioneer DVD players with 1-year warranty and Pioneer Elite's 2-year warranty for both parts and labor, this Marantz has full 3-year warranty for both parts and labor.
What I Like
Solid construction, beautiful front panel, connectivity and low price for feature set, PAL playback and conversion to NTSC, computer video file playback, 1080i, good upconversion. Excellent video and sound, responsiveness, 3-year warranty.
What I Dislike
No DVD-Audio or SACD playback, no USB. Otherwise I would have gotten rid of my Pioneer Elite.
Pros: Price, build quality, nice front panel, features, DivX, PAL, output, 3-year full warranty
Cons: I wish it had USB, DVD-Audio and SACD playback
Bottom Line
If you don't need a USB port, DVD-Audio or Super Audio CD playback, this player is an amazing bargain and an excellent performer. I highly recommend it.

Reviving the Sony Walkman MP3 Player NWZ-S639F
After I plugged my Sony MP3 player (model NWZS639FBLK) into our 2014 Honda Accord EX-L's USB port and selected "iPod" in the car's menu, the player got stuck on the startup screen where it says "Every moment has its music". I tried pushing buttons, resetting the player using the Reset pin hole in its back, etc. Nothing seemed to work.
The player would not turn off. It was recognized by the computer as a USB drive, but attempting to do a firmware update failed. The update utility stated that no player was connected.
I let the player sit unattached to power until it ran down the battery. I then connected it to my computer and formatted it as a USB drive. I then updated the player's firmware using the firmware update application from Sony's web site. The utility stated that I already had the latest firmware, but I could update it anyway.
After the player restarted, it worked again.
