Your problem seems to be same as mine; faulty Z-sus board. Check two last posts under the thread "LG 60PZ550 Plasma - No Sound, No Picture" ([url]https://www.badcaps.net/forum/showthread.php?p=664262#post664262[/url]) to see how I managed to repair the TV.

Check all MOSFET's and IGBT's on board, order the faulty components and change them. Good luck!Re: LG 60PZ550 plasma - no picture o...the thread "LG

Re: LG 60PZ550 Plasma - No Sound, No Picture

OK. So the TV is fine now. There was no way I could get a full Z-sus board anywhere. The only remaining option was to check it myself and change the faulty components.
As mentioned on some other posts about 60PZ550 the coils like to heat up on Z-sus and Y-sus. I checked them and the solder on the joints was visibly cracked. After re-soldering them I went on a search for the faulty IGB's as per some suggestions on the web.
My IGBT's were all ok but after very careful inspection I have noticed some discoloring on the resistors...

Following on the LG 60PZ550 Z-sus problems.
My Tv also have stopped working without any noise or sarky sound.
I troubleshooted it and forund out that Vzb terminals on Z-sus board reads 0V.
So I'm in the process of ordering new Z-sus board.
Will try to post new thread when I'm able to (new member)...
