Ok I've posted about this set before, but I want to diagnose it further. I found my harmony 880 remote that I almost threw in the bin many time so now if people can help me out I might be able to diagnose it better.
Heres the rundown.
Ive fixed the power supply more than a few time now, recap and the 3br chip.
Ive had the resistor blow on it 3 times. I have since most mosfet on that board.
Ive been able to make it work for a while, except when a very rapid change of screen. ie: getting killed in a game.
Lately a z buffer failed, the lower one. Tv worked flalessly with that lower Z board disconnected.
I replaced the lower one, it worked a few hours. Next day, it's back to double clicking, one second screen then off again.
I just replaced the upper z buffer, no effect, as expecting. Still double click.
AS mentionned, I have the harmony 880 and highly suspect the z substain ( the big guy feeding the buffers. Unconnected, it boots. I either have low or weak Vs or bad component on the z buffer pulling too much sauce.
Correct me if im wrong
