Re: Magnavox 42MF230A/37 intermitent and Red horizontal lines

I tried disconnecting the top 2, 3, and 4 buffer connectors...nothing changed.
I tried HDMI input on main board and RCA input on side board...only black screen.
I cycled through all the source inputs, but nothing showed up on the screen, not even the no source box that usually appears when I have the wrong input selected.
The only thing different is that the lines that were on top of the screen are now flashing on the bottom 5" of the screen.
I looked again, and I couldn't find any burn...

I've done plenty of component level repairs.
How easy is it to diagnose?

High, new member here. I love to tinker before I throw out my electronics.
I have saved many a washer/dryer/dishwasher and computer with an inexpensive component change instead of the junk heap.
When I found you guys, my spirits lifted because I have never tried to fix a plasma TV before.

I have a 2006 Magnavox 42MF230A/37 Plasma TV. I think I have two separate problems:

1) There is a red/green/blue horizontal pixel band on the top 5" of the TV. Below it the TV picture is fine. This has been going on for a few weeks now.

2) Using...
