Right then ive tried the lead in all plugs and the switch in both positions,borrowed a known to be working lead pluged into the rca and its still the same.When i unplugged the lead anfd plug it back in it now comes up with " non supported video format" but still has sound.If i switch it off then back on again its just the sound with no message on screen.Last night while messing around with it a switched it on and it worked perfect (with picture) untill i switched it off and it lost the picture although sometimes it was coming on with the picture but it was slightly destorted with a red/green tint to it which while playing the game would flash and give a proper coulered picture now and again.
