I have a Philips Pronto RU990, which I bought early this year 2nd hand off eBay.

Recently it started to re-boot itself occasionally, and I'd noticed the battery life was down to about 2 hours if left out of the dock.

I bought a replacement battery pack from an on-line source last month and it seemed to be fine. Battery life was now over 3 days when out of the dock, and no re-boots.

I went to use it the other day and it was working fine... picked it up to pause a film and the screen lit up white. I thought it was re-booting, but it stayed like that.

Now the screen won't do anything but light up white, despite all the functions working correctly when pressed (guessing the on-screen button locations of course)

I've tried removing the battery pack, pressing the reset button, re-installing the config file (standard and custom) and updating the firmware (already on the latest though), but nothing has returned it to normal operation.

Is it possible for this to be repaired? Are there any known common faults that cause these symptoms?
Thanks,
Stuart
