Cool. Progress. I just replaced the Y-main. Do you recommend another Y-main at the same time as the X-main? Or can I likely just buy an X-main?Leave a comment:

shorting pins 3 & 4 fails. No test pattern, no changes whatsoever.
Another possible tip. When I plug it in, I get one click followed by a "bizzip" sound, possibly from the power supply area. I can't quite pinpoint the location.
Thanks in advance for your help.Leave a comment:

When the tv stopped working, I swapped it out for a Panasonic plasma. Then I could not get the DirecTV to complete it's initiation. It would get to "completed steps 1 of 2..." and that screen would go blank. I called DirecTV and they came out and diagnosed a bad HDMI cable.
So, could a bad main board destroy a cable?
I'll do the test this eve and post results.Leave a comment:

and if it produces these test patterns, does that indicate I need a controller board?Leave a comment:

Samsung PN51D430A3DXZA Sound but no picture
20 month old plasma with no picture. I've read several posts on here and learned a good deal so far, but need help with the next step.
I took the back off, but don't see any swollen or leaking caps. I measured VS and VA, and initially get VS=~205 and VA=~50 before both gradually decrease, maybe 10 volts per second.
I replaced the Y-Main board with ebay find, but same status. I unplugged every board leading to the power supply except main board and input board, since they appear to be required for power supply operation. VS and VA still fall the same way.
