Re: 50" Plama vertical lines - repairable??

I heated them with a hair dryer and then I froze them with a spray.
Now there seems to be horizontal bars in the mix.

These horizontal bars are not static (Vs dynamic)
They kinda flicker about.
They have vertical black and white lines within them.

can you pinpoint the exact capacitor that you heated up or free sprayed to see the difference. Normally with this board I would replace all three of those 220 microfarads with standard electrolytic caps

All three. And the other components in the area.
The hair dryer is not selective.
I also froze all of them.

It was the main board. I replaced it and all is good.
I am VERY thankful for this forum, its a great site.
Now I have a faulty main board that someone may want for spare parts.
Probably has a badcap in it
