Hello! I've searched around but I haven't been able to find anyone else who has posted about this problem and I am desperate for some help.

I have an N800 that had worked fine. Now the touch screen stops responding unless the power button is pressed, and then it responds for 10-15 seconds before dying again. To clarify a bit more, I can turn the device on and navigate most the menus as long as I press the power button every 10-15 seconds to keep the screen active. One more issue that may be related is that the audio is also no longer functioning.

I've removed the SD cards, cleared the memory, restored the defaults, and have tried flashing the device to os2007, an older os 2008 and the most current release. The only thing that changed the problem was that with os2007, pressing the power button wouldn't reactivate the screen.

If the problem wasn't so strange I'd chalk it up to the hardware being fried and give up but I'm hoping someone else might have another suggestion. Any help is appreciated!
