Got in the car this morning, and pulled out the PDA since i needed to use TomTom. I looked at the screen and there is a streak of black lines going through the middle of it. When the PDA is turned on, the pixels are a combo of red/green etc. I assume these are dead/Stuck pixels? When i left it in the car lastnight it was fine. Maybe it hit something in the glovebox or maybe it was because of the freezing weather? I am thinking the cold must have caused them. Is there anyway to remedy them? The PDA is an Acer N35 used purely for tomtom. Pity, since its excellent for Navigation.
