LP 60PK540 Plasma has audio, but no video.

[oxzyss]

My 60" plasma is only 1.5 year old and one night, while watching a movie, its video suddenly disappeared. The audio is still there. There is nothing flicking at all while powering on/off. Over a period of a month I have purchased and replaced Y Sus, Z sus, and also the control boards from a reputable vendor. The situation with the TV remains the same. I have measured the outputs of the power board to Y and Z sus' and the voltages are as stated on the boards. All the fuses seem OK, too. I have disconnect either up and bottom buffers connected to the Y sus, and did not see any change to the video. Are there any further test that I can do to explore the situation? Thanks in advance.

By the way, while connecting the buffers, I damaged one of the two connectors between Y sus and buffers boards. Any kind soul knows the part number of this fragile looking 20-pin connector? Thanks again.

Perhaps it's best to ask a mod to move this to the TV forum -- this section deals more with computer monitors.

Regarding your problem, can we have some pictures of the TV's chassis (parts layout) and one of each major board?

I've got a block diagram for the 60PK750 (it uses a 60R1 panel like the 60PK540 so it should be more or less the same) which has some checks:

including some meter test points.
