Re: LG 50PC1DRA - Screen slowy fills up



See previous post about heat gun. I did pull the y-sus board out and looked it over. I did not have much time to mess today but did pull C143(47uF 160v) and it read 46uF. Cap near -Vy and Vsc was C50(33uF 350v) read 32uF.



Can you explain what is involved in fixing the suspected areas(besides any caps) you listed? Also, I will try the heat gun again tomorrow to make sure that it indeed cause the screen to fill up faster....

Re: LG 50PC1DRA - Screen slowy fills up

I went ahead and hit the Y-sustain board with a heat gun a bit ago and the picture did indeed feel the screen faster than it was before.

Here are a few pictures of what it looks like with a signal going to it. It has a very grainy picture. Not sure how to describe it. Fuzzy or static if you will. Is a faulty z-sus or y-sus causing this static or is this another issue on top of the slow screen fill?





To tom66, my z-sus board is 6870QZC004B while the one you listed is 6870QZC004C....

Thanks for the quick replies. I do not see any fuses on the Z sustain board. Perhaps it has surface mount fuses?

I am pretty handy with a soldering iron. Also have a good desoldering station too.

Is this board fixable? If so, is it usually a cap situation or other failed components? Or is best to just replace it?...

LG 50PC1DRA 50" Plasma

Was not powering on. Pulled power supply and found 12-15 caps that were bulged. Replaced all in question and now TV turns on. Problem is that something else is obviously wrong.

When I first power it on, only right side edge had a picture. Rest of the screen was black. Had no signal going to TV so it was just your standard fuzzy picture. I noticed right away that the picture was growing. The fuzzy static was spreading slowly, eventually filling up most of the screen.

While the screen was slowly filling up, I got the menu to...
