When we turn our NEC PX-42VR5W Plasma TV, we get a screen with pink and green vertical thin lines over the whole screen and it stays that way for approx five minutes then a normal picture comes on but from time to time it changes to different coloured wide vertical lines. We have had a serviceman out and he checked the Samsung VCR/DVD recorder and also the Set Top Box and said that the problem is definitely with the Plasma (not the screen) and told us to call a plasma tv serviceman as he doesn't do them. Can you give us any idea of what the problem may be. The TV is approx 3 years old.

Somehow when switching between the tv and the dvd my wife encountered the pink and green, thin, parallel, vertical lines on the screen. The picture was visible with the lines. I turned the tv off and on but the problem persisted. Unplugged tv for about two minutes and after plugging it back in and turning it on the vertical lines very gone and the picture was back to normal.

Despite the fact that you have posted this as a question about a kitchen range, I can tell you waht the problem is anyway!

The plasma screen is controlled by hundreds of seperate connections at the top, bottom and sides of the screen which use electrical pulses to signal the pixels on the screen what colour they should be. If the connection to a bank of these connectors fails (in this case either at the top or the bottom of the screen) then they will usually die and that portion of the screen most commonly goes black. Next most common is that they go white as yours has.

This is absolutely NOT a DIY fix. You will need to get it to your local TV shop. If you're lucky, they will find and fix the poor connections. If you're unlucky, the plasma panel has had it and they won't be able to repair it. A replacement panel supplied and fitted is probably about the same price as a nice new, updated plasma TV, so if the issue goes that way, consider scrapping and buying a new one

one of the module in the main board has a problem try to contact the service center.

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.

dry solder in vertical section or ic faulty replace it

Sorry to tell you, it is not a scratch, but a bad cable connection from the driver IC's, connecting up the plasma screen to the drive board, or the drive IC for that section of the screen is defective. It is not a repair a user can do as there are no user replaceable parts inside this set. Your going to have to call NEC or an experienced Plasma repair shop.
