I have a TC1100 tablet. Yesterday it started acting strange. The display wouldn't light up when I turned it on. I removed the battery, hard drive, and power adapter for a few seconds. I also removed the user accessible RAM. Tried booting after each test. I did get it to boot to windows twice since yesterday. I thought it might be a hard drive problem so I set it up to run scandisk on the next boot. When it rebooted the screen started acting weird. There was a row of black blocks across the screen just under the middle when it was going through the scandisk. Then it appeared to freeze. I shut it off and then the screen wouldn't come back on. After several hours I finally got it to boot to the scandisk screen again. It wouldn't complete, and froze with a bunch of vertical white bars in about the same location on the screen. Rebooted again, and it won't do anything. The power light and charge light do come on. Today, I tried again, and sometimes I can hear the windows theme playing, but only a black screen. Sometimes all I can hear is the hard drive and the fan spinning. Sometimes I can see the screen back light on, but no image. Just a faint glow. Any ideas? Hard drive problem, RAM, inverter board, display, bad motherboard? I know this is an old tablet, but it works for what I need, just trying to figure out what happened to it.
