Re: Samsung PN51D7000 plasma TV: No display after loud "pop"

I think I'm getting somewhere.

I disconnected all three connectors from the Y-sustain board. Now when I turn the TV on the LED on the logic board turns on for a half second every second. Using the test points on the power supply board, for Vs I get 208V (sticker says 207V) and for Va I get 58V (sticker says 58V).

This would seem to indicate either the Y-sustain and/or Y-buffer boards are at fault. Is it to be expected that, with a bad Y-sustain board connected, I would get readings...

If I check Vs on the power supply and other boards I consistently get only 0.4V. For Va I get only 0.03V. If I check the pins labeled 5.3V on the cables from the power supply to the logic and main boards I do get the correct voltage.

Also, looking closer at the components on the power supply as seen in the attached photo, are those leaking or is that glue? The bottom one in particular has yellowish gunk all down its sides....

I see several fuses on the power supply board but none on the Y sustain. Unless I'm looking for the wrong thing?

I do not have a multimeter at the moment with which to test. What/where would I be checking on the power supply?

The buffer board is the same as the scan drive, correct? Would that mean both that and the Y sustain would need to be replaced?...

I have a Samsung PN51D7000 plasma 3D television that was manufactured in October 2011 and purchased a couple months after that. It has worked without issue until recently I was watching TV one night and it made a loud "pop" or "snap" noise. The display turned off but the audio kept going.

The only devices I have connected to the TV are my HTPC (via HDMI) and a Wii (via composite dongle). Audio plays through the built-in speakers in either case.

Here are the symptoms I am experiencing:[list][*]When I plug the TV in it "clicks" on (the...

Re: New Members - please post your introductions here

I'm from the suburbs of Chicago. I've been doing research on how I might fix my plasma TV and figured it was time to actually ask for help specific to my make and model; this forum seemed like it was tailor-made for my issue. I work with computers, though more on the software side than hardware, and am not all that familiar with electronics components, so I'm hoping some of the better-informed minds here will be able to share some wisdom. Thanks.
