This sounds alot like the same issue I had with my HP 42 inch plasma. Many plasmas had an issue with failures on the YSUS and ZSUS printed curcuit boards.
If you are willing and able to do some dissasemply yourself, open the TV and see if it uses these cards...if so then look at the solutions listed for the HP PL4260N TV issue.
I found the fuse blown on my YSUS board, I removed it and had it repaired by coppel TV..if you find a board that is bad, chances are someone on EBAY repairs them or swaps them out...mine cost $75 to repair and I was back in business...TV works fine again now that I had the board repaired.
its the buffer driver board the big long board that plugs into your tv,, i have one for sale if u need one,,30£[email protected]
free+p+p
this will cause the lines on your tv after replacing the ysus it could well be that ysus mabe faulty still if u replace buffer and find u still have the lines 9/10 times when the ysus goes it normally takes out the buffer board on these worst cases the control board,, but im 98% shure its buffer board.. let me know on here if u find out.
I have the same problem the pic went out but have sound. where do i go to get the Yboard? do i need a special number off of it or something? I took it to repair shop and he said it would be like 500 dollarss to repair. but i see all kind of yboards on ebay for like 150?? how do I know what one to buy?
its usually replaced along with the ZSUS board replace that and it should solve the problem its not hard to locate that both with the back cover open its to the right side of the kinda kinda looks like the YSUS board not hard to find at all
Norcent PT4233 no picture, black screen, but has sound. How to repair
The display (PDP - Plasma Display Panel) at the heart of this unit is a LG 42V7 model. There is a known bad solder "defect" on the YSUS board that causes this board to fall unexpectedly.
The bad news is that you have to replace all the primary boards on the display - ZSUS, YSUS and CTRL boards, as the failure can/often takes them all out.
The good news is that LG makes a repair kit for this panel. Its part number is 687VSNB03E and it contains the three boards LG6871QYH036D (Y SUSTAIN), LG6871QZH041B (Z SUSTAIN) and LG6871QCH053G (CTRL).
call 877-543-8325 this is an LG Executive call center and they will fix this for free. I have a 50" plasma I bought january 2006 which is out of warranty by 5 months. They faxed me and the LG repair shop a 30 day warranty for my tv to cover the repair. Just tell them you heard a pop and in my case the picture is distorted. All they need is the model number and serial number and they should take care of it. No arguing needed.
