2 yr old Panasonic Viera 37 in - has very narrow

If you let me know in which location of the screen is located I can assist with the possible cause since the vertical line can be caused by different items based on where its located on the Screen such as center of screen, or far right side or midle of the right half side of the screen. Reply to this same post with where the line is located and I will assist you with it.

Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER
HOPE THIS WILL HELP TO SOLVE THE PROBLEM.....

Hello,

All plasma TVs have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them.


I hope this will help out in solving the problem ......

YOu have no vertical deflection. Call the repairman.

chake to make sure it is hooked up right and not lose

this problem sounds like bad solider on the vertical IC chip.
re solder pins and should run fine.

Sounds like your flyback converter is burnt out and yes if this is the case it would be worth fixing!
Good luck!
