As with any problem, check all voltages. There is a sticker on the rear pannels with the VA
and VS voltage listings. If ok my first suspect is the Z-sus board

I would first check the lg support site to see if there is a firmware update if not look at this link to my Samsung it might help https://www.badcaps.net/forum/showthread.php?t=34217

Cant see any firmware updates, I have checked the voltages, VA should be 60v and shows 59.6 and VS should be 184V and it was at 185.6v, If the Z-sus board is the fault is it repairable at a component level as i have been advised against buying used parts??

All I can say is to try and up the vsc and see if picture gets better (do not leave it high as it will damage the boards) if so I can only suggest its x-main and y-main fault that's what sorted my Samsung but you may have a different fault. As for component level im unsure I did test all of the caps on both my boards and they were fine that's as far I was willing to go. I would buy boards as long as they match part no and rev.no and replace as a pair. Check out eBay member sivill123 he helped me out a lot and done a deal for both boards very helpful and fast delivery I found.
good luck

I recently had a "red fuzzy picture" issue with my LG 50PS60 TV. At first, this issue was sporadic. The TV would work okay for an hour or so, then become unwatchable. Finally, the TV would come on for 5 to 10 seconds, with no picture, then shut off.

I thought it would cost too much for an "official" repair, so tried to troubleshoot using the internet. (Yea Badcaps!) From the data available, it seemed my symptoms indicated a potentially bad Z suspend board. I could buy a new Zsus board (not a rebuild and not from an otherwise damaged TV) for $90, delivered. I was willing to try this, especially since no electronic adjustments were needed when replacing this board. (The lack of electronic expertise [I'm a mechanical engineer] and equipment made me hesitant with changing the Y suspend board.)

Well, I got lucky. Changing out the Zsus board was straightforward and it fixed the TV. So if you're having the "red fuzzy screen" and shut down problem, it might be worth changing the Zsus board. One thing to do to give you confidence the Zsus board is the issue is to remove or disconnect the Zsus board and turn the TV on. When I did this, the TV would stay on and I could use the internal TV menu to view the setup screens. The picture was still red and fuzzy, but at least the TV stayed on.

Good luck!

Yes, with the 50PS series, Z-sustain failure is common. I found one on the street, repaired Z-sustain and it fired into life. Someone threw it out for an easy fix, that's their loss...
