My NEC LCD monitor suddenly starts 'weeping' and I get vertical black and white lines from the left up to middle of the screen


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

Thin red line in middle of screen on nec 42 inch plasma monitor


I had the same problem -red, vertical bars along the right side of my Samsung 42" Plasma- and this is what fixed it: Removed unterminated cable.
I had hooked up an HD video camera to the set about two weeks ago. While I disconnected the camera I left the other end of the connector cable plugged into the T.V.. As I've since learned from friends who work in television, this is what's called an "unterminated cable" -meaning one end is unconnected. It can lead to problems with electrical interference and appears to have been the problem in this case; When I disconnected this cable from the T.V. the red bars went away.
So, check your cables. Make sure everything is properly connected and get rid of anything that might be picking up interference.

Nec plasmasync 4200w 3 vertical lines one yellow two purple


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.
