It could be either the plasma panel itself has failed or one of the driver boards has either failed or has developed a poor solder connection where it connects to the panel. Unfortunately, because of the high voltage contained in the unit, I cannot suggest you attempt service yourself, as there is a real shock hazard. You will have to contact a servicer to look at your TV. Sorry!

    I still think my previous posting is correct, either a bad plasma panel, bad driver boards and/or poor solder connections. Sorry if this isn't the solution you're looking for.

    BTW your unit doesn't have a convergence IV on the power supply or anywhere else for that matter.

    get it replaced or repaired.

    you can do it your self if you have any technical knowledge.

    you can get the required IC at

    thanks.

    sometimes it also happens doe to heavcy voltage passed through the electrical line from which your tv is connected.

    so if this is the cause

    you can off the tv unplug the device from the main power socket and leave it for 10 minutes.and then connect it somewhere else and then try.

    if due to heavy voltage passed this happened it will resolve after you plug it again.



    thanks.

that's part/pin lost contact, you need to remove back cover and trace possible lost contact. just concentrate on vertical section as you seen for vertical line on screen. try to resolder all pin on that section.

I have a plasma tv that has two black lines about 50mm wide running vertically in the centre of the screen


Three kinds of detects count for this problem. It could be the Logic board, or the Logic Buffer board, or the PDP panel. Just drop your tv to the warranty depot shop to repair.

Hello,
I have the same problem with vertical coloured lines on my NEC PX-42VP4G/S. The photo only shows a black background just so it's easier to see the lines in the photo but normally the picture is OK except for the vertical lines which aren't always in the same place.
If anyone can advise on exactly what I need to replace then I would be very grateful.
Regards, Simon.

Colours split and vertical bowed green line at to and bottom of s


This is a convergence problem that can be either poor solder connections at the convergence ICs or defective ICs. If you can solder and feel comfortable working inside the set where there are potentially dangerous high voltages, update this and further details and instructions will be provided.

Thanks,

Black vertical line 3inches in from the left on my fujitsu PDS4233W-H plasma screen


If the line is all the way from top to bottom, it could be your upper and lower buffer boards or your plasma display unit is bad. I suggest you contact a servicer for your brand.
