My PMP MP4 DC DV china make player's LCD screen does not work. The device switches on okay but no LCD display. The charging is okay and when I connect to a computer, it is detected. The only button which works is the reset button and it swithches off. No other buttons are working and I cannot switch it off using power button. Please help.

Open it up, post board ID and CPU...

Even though this is likely not a firmware but a hardware problem, knowing what that hardware is will make it easier to determine the problem.
