Samsung Plasma TV, looking to repair

by | August 2, 2017 12:29 PM PDT

I am in no way an expert in Plasma/LCD/LED Flat screen TVs. That being said, I am savvy enough to know how a multimeter works and how to safely do work on electronics. I have a Samsung plasma tv that has no picture but has sound. The research that I have done points to replacing the Y-Main, which I understand is what turns on the screen in the first place. My question is: Is there a way to test the Y-main board to see if it is indeed viable? I had another tv, LED back lit that I played the "replace the parts till it works" game, I replaced the Main board and the graphics board before I discovered that it was the T-con boards, which was by far the cheapest and most readily available part.

TCON? I thought plasma used sustain and driver boards.

Anyhow, moving on as the LCD displays use timing control boards.

Light into to testing at https://www.badcaps.net/forum/showthread.php?t=26790

So here's some video by Shopjimmy on plasma but if you are SERIOUS you buy the service manual.
In the USA it's over at samsungparts.com. NO TV TECHS ARE SHOWING UP HERE.
I'm just an electronics designer, software author etc.

You are correct

They do, i was referring to a LED TV that I repaired some time ago. I've watched that video and yes you are correct, Shop Jimmy has some very informative videos, in fact it was this video that pointed me in the direction of looking into replacing the Y-Main board. They don't charge much for a replacement, only about $100, I just would like to try to test the board to see if it might be something else. I've been trying to find a service manual or other source that might be able to tell me the specs, outputs and such, so that I might check its status.

But without a model number I can't check if the service manual (USA models) is up at samsungparts.com. Check that out next.

Found it

It's alright, I used the site and found the service manual. I'm not a huge fan of paying for a pdf but I guess I'll have to suck it up, I just hope that its in depth enough to answer my question.
