I had a serious problem with my Sony PRS-T3. '''The screen is completely frozen and I have to open the device to reset it. '''I have check the board (visually inspection) and there is no trace of heating or water condensation).
And guess what,''' the device work perfectly and flawlessly until I put the plastic cover on it. And again it freeze and I have to go back to square one. '''I have also try using some spacer before closing the device without any success.
Do you have''' any idea of the localization of the problem.''' May be a bad connector or something like that.
'''I need your precious help !'''
