I can't get this phenomena to repeat itself now.

I've decided to replace the Y Buffer board (called the bottom Y scan drive on SJ), since it's cheap enough and I'm fairly local. I'll know tomorrow if that'll solve it.

I look at it this way: Unplugging the cables on the Y Buffer and messing with all the cable plugs on all the boards jarred something and made it work properly for a real short period, maybe the issue lies in the cables or the buffer.

The Y buffer board just arrived. I installed it and, as I kind of expected, no luck. I've now replaced all boards except the e/f buffers below, so in theory this should be working now. I don't even know what to look at next. Any ideas?

This is a real stumper. The problem is not obvious. The only thing I can think of is that one of the parts you got is bad, but that just seems unlikely to me... No easy answers, I'm afraid.

That's what I'm thinking, as well, but I'm unsure how to explain to SJ I need all six boards replaced after less than a month lol. Doing it one by one will be a ton for shipping. They're only two hours from me, but still.

Re: Samsung PN43D450A2D help needed

Sorry to bump an old thread, but I am also having issues with this model TV and its click of death. I have checked voltages coming from the PSU board and have found that the only pins putting out power are the PS_ON and STBY pins. Nothing else is even registering. Would this mean that the PSU is faulty or should I look into other issues?
