I have vertical lines and horizontal lines in the picture of my tv. The horizontal lines are blacker than the picture and the vertical lines are colored, I thought it was the main board(the A board), so I replaced it and I still have the lines. It doesn't matter what input it is on, the lines are still there. Also the red light doen't blink at any point, it stays constant when I push the power button so I can't diagnose it that way. Any help would be appreciated.
This is a plasma TV to which there are driver boards Top/Bottom, Left and Right.
Sounds like some of the driver main transistors have gone bad.
Wondering how old the TV is?
Honestly may be best to search for a new TV. Sorry to break this to you but its the law of supply and demand and there is such a glutton of TV's, Plasmas, LCD and LED tvs out there.
Sorry to be the bearer of bad news. As a tech I hate telling you this. I don't make the money fixing these older units. Cheaper to go out and by new with a warranty!

The tv is only three years old. I can fix it myself, I just don't know which board I need to replace. I was hoping someone had a similar problem and fixed it or had it fixed and could tell me what board it was.
