The picture on my fourth generation plasma was great up until last weekend. I'd been inputting my arcam DV88 via VDC component leads. I put on A Beautiful Mind on Sunday evening and the picture was covered with a mask of parallel lines, every 2 minutes or so the lines would disappear and the picture would be perfect once more but then they would come back 30 seconds later. It's wasn't the disk, I tried half my collection to the same effect. I tried inputting the DVD player via VGA using my JS RGB Scart to VGA convertor and the picture was 100% - it's something with the component signal. Anybody got any suggestions or ideas? The setup was literally unchanged, it just suddenly strarted with the lines.
