Offhand there are two potential and common causes of the screen getting light after the set's been on for a period of time. First and most likely is the power supply board in the TV- which has an output that drives the LCD controller board (called the T-con) and when this part becomes weak/intermittent- will cause the screen to lighten to an almost white hue. Secondly is the T-con board itself- which processes all signals before they're sent to the screen. To determine whether the issue is caused by the power supply board- or the T-con, a tech must measure the voltages off of the power supply board (the 12 volt line feeds the T-con) to determine if it's in spec. If it's not- the power board needs to be replaced (which is on average a $275 repair). If the voltage IS in spec however- the T-con needs to be replaced ($200). In some rare cases- this can be caused by a failing LCD panel (screen) of the TV itself (however there is no way to test the screen beyond replacing the T-con to see if that fixes the problem). If the screen is deemed faulty- the set is not repairable as the cost of the screen is 80% of the cost of the TV.
