Hello everyone,
This is my first post here, I'm fairly new to TV repair as well.
I have a 42 inch HP plasma TV with the usual sound but no picture issue. After replacing the Ysus board, the TV came right back to life.
Unfortunately, there was a single thin horizontal black line along the bottom the lower half of the screen. Thinking it was most likely a loose ribbon cable, I opened and closed the ribbon cable a few times, (here comes the dumb part) with the power on.
I know, I know, I know, stupid.
Anyways, while doing this, I fried something and now the picture has vertical lines running top to bottom and colored squares everywhere. They are not in one place, they are scrambled and move around. For example, a color that should appear in the image on screen appears as an entire vertical line top to bottom during those frames.
I have not ever seen this symptom, but I suspect I just killed the new ysus that I installed? Either that or the buffer board. I see nothing obvious upon visual inspection and all fuses are intact.
Thank you in advance for any help
**The pictures show what would normally be the menu screen with the hp logo floating around. The thick vertical line moves around in the same manner***
