My PSR-800 Will Not Power On
No matter what I try my PSR-800 will not power on. However I know it's getting power because it will show the Software Update Screen. I believe it is stuck in this Software Update mode and that is why it won't power on. The reason I believe this is that I can get to this screen simply by pressing the Menu button. Normally, I wouldn't be able to do this. Normally, I would have to remove the USB cable, and then while holding down the Menu button down, plug in the USB cable. However, I can access the Software Update Screen any time there is power to the scanner. Also, the screen seems to be missing some information; see image below...
Normally I would see four lines of information, however now it is only showing three. Also EZ Scan recognizes the SD Card but is unable to access it. No matter what I try with EZ Scan to work with the SD Card it always produces an error message. It does recognize it just fine if I remove the SD Card from the scanner and put in in a card reader. Then EZ Scan works just fine with it. At least this allowed me to make a full backup of the SD Card. While I had the SD Card in the card reader I used EZ Scan to format it and do a new update of the Library files and then restored my programming from my archives. However, when i put the SD Card back into the scanner it still has the same problem with not powering on.
I've learned from a Yahoo group for the PSR-800 that the on/off power switch is controlled by the same chip that controls the clock and that there is a capacitor that retains the clocks power when the batteries are removed and the USB is unplugged. The Yahoo group had a discussion about a similar problem where the solution was to remove all power, batteries and USB, for ~ 5-10 minutes. This was suppose to be long enough for the capacitor to fully discharge. This seemed to work for the users in the Yahoo group, but it does not work for me, even when I tried to leave the scanner without power for several days.
Like I said I've tried everything I can think of and nothing seems to work. I'm reluctant to take it apart since I have very arthritic hands and don't trust them any more to work on things like this. If all else fails I'll probably look for somewhere that can work on this. I've heard good things about G&G Communications so I may give them a try. But first I thought I'd ask here in case someone has seen this problem before.
Has anyone else seen this problem? If so did you find a solution?
Thanks for listening and for any help you can provide.
