Got an HS1 in february 2002, approx 2600 hours on the clock now. The picture started showing shades of green/turquoise at approx 2000 hours. I thought it was the bulb on its last legs. Got a new bulb (took its time arriving :-(), fitted it, no difference. Tried tweaking picture settings (even through service menu) to no avail. Found a few things on the forums but mainly panasonic related. I have also tried a different S-Video cable to the PJ, problem occurs with DVD and TiVo, all switched through Arcam Alpha 10 Amp. Could the amp be at fault ? What's going on ? Is there a cure ? Cheers.
