Re: Samsung Plasma 51" PN51D450A2DXZA - No picture
After checking my old and new boards with a Fluke 87Ex they're all fine except the buffer board. So I'll be sending the 2 boards I ordered back and getting a refund and order a new buffer board and hopefully fix this issue.Leave a comment:

I just seen your post. I'll have to check when I get off work.
Correct me if I'm wrong but I need to check the pins that go from the power supply to the Y-sus?
Also I'm not really sure what an igbt or a fet is. Is it the portions on the heatsink with screws? I'm still kind of new to troubleshooting things like this.Leave a comment:

Even though I just replaced both X and Y boards?
The shorted pins on the bottom section go to the bottom IC. All 4 connections have open and closed points going from the buffer to the Y-sus.Last edited by tleake3; 08-12-2015, 03:58 PM.Leave a comment:

Ok so I checked the Y buffer and some of the pins that connect to the Y-sus are closed and some open. I did get one of the bottoms connections has some shorts when I'm checking on the SVC-OUTL port but when checking on the SVC-OUTH I get nothing. Same goes for checking the pins going to the Y-sus, some show open and some closed depending on which SVC port I'm on.Last edited by tleake3; 08-12-2015, 03:50 PM.Leave a comment:

Ah, thanks. Yes I do know how to check for a short circuit. I watched a video earlier on how to check the y buffer for dead shorts and I'll do that first thing when I get home this evening....Leave a comment:

Samsung Plasma 51" PN51D450A2DXZA - No picture
Ok so I've had this tv for about 4 years. I was at work one day when my wife sent me a text telling me the tv didn't work. I called and she said she turned it on, the screen flashed and went black then started playing sound but no picture.
I went to google and started looking for similar problems. I read that sometimes the Y-sus board goes bad and causes that and that the X-sus/main needs replaced as well as it can go bad due to a bad Y-sus. Correct?
Well I ordered both boards from shopjimmy and replaced them yesterday. Powered the tv up and still a flash on the screen...Last edited by tleake3; 08-12-2015, 12:37 PM. -
