I've had the Sony 40W4000 for a few weeks now and its a superb TV. Occasionally, however, when i'm watching a DVD or Bluray over HDMI from the Panny DB30 the TV just suddenly switches over to RGB 1. First time it happened i thought I might have sat on the remote control or something but noticed that it was neatly placed on the coffee table. There was no obvious reason for this to happen. It still happens now at completely random times. Sometimes it won't happen at all, other times it can happen twice. Anyone else have this problem? Or have a set something up wrong?
