Does it have a buffer board? If so, check the IC burnt on the buffer board. If bad, replace the buffer board. Check the flexible connector exactly below or above the black line. Is it inserted correctly? Does it have an IC on the flexible cable? Is it brunt? If so, you need a panel. If the buffer board is OK, then you will need a panel

Two vertical black lines on the screen of my ps50b430


Unless someone played with the TV and disconnected the plasma display from the address buffer boards that go under the screen the prospects aren't good.

All vertical lines in all plasma TVs I have seen are operated by chips embedded in the fabric of the display as well.

When they fail they'd either short or burn open.

In the first case they'd prevent the TV from coming up, in the second they'd typically manifest as either black or a random color vertical line like you have.

This is not repairable...sorry.

The odds of this being something else is fairly minimal in my opinion.

Please don't kill the messenger...

I have a thin yellow line running from top to bottom about 10 inches from the left side, what's wrong?


This can be due to faulty LCD driver IC which creates a noise bar and is shown. Check the cords to the display and also the ground connection to the display. If this is good then the IC can be faulty.

I have a permanent dark/black 4.5" wide vertical line on left side of plasma TV. It seems as if it is 4:3 display mode on left side only. Any help would greatly be appreciated. I have no problem changing...


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 .

BUT IF OTHERWISE CHECK
x driver cables 10 ohm resistors have loose connections
Hope this will help...

I have lost my remote for JVC TV GM-V42S. Where can I get one? Thx Rod


I contacted JVC professional to find out the model number for my JVC GM-V42E. Once you have the model number, contact JVC and order a new one or google the product number and try using websites that are dedicated to providing remote controls, I was able to get one from avukltd.com a little cheaper and more quickly than JVC said they would have the product in stock.
I also found the remote control product number on the bottom of the plasma screen.

JVC GM-P420E Plasma no video green screen


the problem is with the micro processor on the back of the fx-1169a board (gm-p420ug) this is the board the inputs connect to . yours may be a diffrent p/n due to yours bein a "e" extention model. to repair this problem you need to remove the processor from the socket, remove the socket from the board and solder the processor onto the board. the processor is ic002 on the back side the problem is thermal in nature due to cold solder joints on the socket. i have fixed this problem many times by using this method.
