Re: LG 60PZ550: Sound, No Picture

Disregard previous message. VSC and VY are not nominal as seen below.

Ok so I have measured the voltages and here is what I got

VS 199V
VA 53V
VSC 1KV+
VY 1KV+
VZB 108V

Re: LG 60PZ550: Sound, No Picture

Here is what I have done thus far.

1)Co-worker said plasma had blue/pink spot in certain areas of screen.
2)Confirmed screen issue
3)Research lead me to the multiple threads about the cracked joints on the inductors.
4) Pulled ZSUS and YSUS out and indeed had cracked joints.
5)Resolder all cracked joints. Resoldered all joints that appeared dull, disturbed,cold, etc...
6)Reinstalled boards, but TV would come on for a second then shut off. I could hear the relay switching on and off on the supply board....

I have come into a LG 60PZ550 and am trying to fix the problem. I have done the pattern test with no results and am needing further advice. Please advise as I am quite at a stand still.
Thanks.

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

So after the pattern test is complete and I have found no visible outcome, where do I go from here? After all of SCCrepair's troubleshooting, we have not been able to figure out the problem still. Please any info that could help would be greatly appreciated.
Thanks.
