| What is screen burn and does it affect new flat panel TVs? |

|
Screen burn is where a ghost image of a channel logo is left on the screen once the set has been turned off or onto another channel. The problem doesn’t affect LCD TVs but plasma and old fashioned CRT TVs are susceptible. However, broadcasters have toned down the brightness of their logos and the latest plasma TVs boast screen cleaning technologies to combat the problem. In our tests, images burnt on to the screen after a day, disappeared after normal TV viewing. After leaving a channel logo on screen for a week only one plasma TV (out of six tested) suffered any permanent screen-burn. |
