As an AV virgin can anyone help me? I have a Panasonic TX-28PL10 which is now a few years old. Occasionally the picture will just fade out to either a completely red screen or more recently a completely green screen. It is a gradual process but eventually leaves the screen as a negative type image in a predominantly green transparent colour. It normally occurs after the TV has been on sometime and is normally ok again when left turned off for some considerable time - overnight!
