screen has no contrast

well i noticed that the screen on the has real bad contrast. real bright. maybe my fault as i had it set for never turning off and had the weather bug running all the time. but i also had it plugged in and now and then would unplug it to let the battery drain and then recharge. but i needed to take it with me the other day and stopped the weather bug. and the screen looked like it was burnt in. i did not think lcd screens burnt in but maybe they do. i turned it off for the weekend and most of the burn in was gone but it still has no contrast. so tell me is it now junk? or maybe i can run a dark program to cause it to get the contrast back? is there an ap that excersies the screen like a screen saver?

thanks bp.

 

so who is correct one says yes one says no and if an app can fix it which one? thanks

 

it is a Polaroid model pmid701c i think that is lcd. i had it on the weather bug for a week or so and on the charger so i took it off the charger and let the battery run down so it would not set the battery. when i shut it off it looked like it was still on. the screen looked like it got burned in like the old crt's did. i did not think the lcd would burn in. anyway when i started it the screen was so bright i could not turn the brightness down far enough to take it away. my guess is it is toast not worth fixing but if there is an app that may exercise the screen it may come back. thanks

 

ok then thanks for the help it is junk. not sure why the back lighting would make it go bright but then i guess if it got stuck on it would. thanks for the help.
