The components arrived, now the TV works as new.
I just changed the broken transistors and the 4A input fuse so now everything is fine.
I will post some photos. Thank you guys for all your help

Re: HELP! LG 50PQ3000 Plasma TV Repair
No, it's not a multi layer board. I just reconstructed the circuit were it was broken.
Now I have to wait for my 30J124 and 30F124 transistors to come. It will take a long time, hope less than 1 month.
I have enough time to verify each component, I will try to verify the drivers also.Last edited by alwaysfresh; 02-01-2015, 08:40 AM.Leave a comment:

Is there a way of testing the driver?Leave a comment:

Re: HELP! LG 50PQ3000 Plasma TV Repair
But is it plausible that the crack on the PCB to be the real cause for destroying my IGBTs?Leave a comment:

Re: HELP! LG 50PQ3000 Plasma TV Repair
Forgot to say, the Ysus board is EAX60987801 model.
And if I replace the IGBTs, do I need to adjust any resistors or pots?Leave a comment:

HELP! LG 50PQ3000 Plasma TV Repair
Hello guys, this is my first thread on badcaps forum.
I am asking for your help in repairing the LG50PQ3000 plasma I got.
Its initial problem was that the TV wouldn't turn on, and it made that clicking sound. It had no voltages on the PSU, just the some unstable standby 5V. Changed the VSB3200 schottky diode with some equivalent (not schottky) and it works.
Ok I turned on the TV and voila... entered the menu, configured the programs. After finishing the auto programming job (10 min maybe), the display suddenly shut down, heard some noise before this,... -

did you manage to solve the problem of the old PSU?Leave a comment:
