Re: LG 60PZ550 plasma - no picture or sound ...

I have LG 60PZ550 PLASMA TV. The first the problem was no picture on screen but only audio. I opened the back panel and found the ZSUS with fuse blowed out and coils sink welding ckacked. I changed the fuse and welded back the coils on board. Now I turn the tv ON and quickly it turns back OFF. I disconnected the ZSUS board and plugged power back ON, on but no picture, also I noticed buzzing noise from ZSUS board. I removed the ribbon cable from CTRL to YSUS board and noise stopped. I also did the test with the jumper on R51 and R52...
