SOURCE: Horizontal lines on NEC plasma

Intermittent horizontal deflection
Resoldered the pins of horizontal deflection transformer
Picture is horizontally narrowed and deformed
Capacitor C2913 (390nF, 250V) on the deflector PCB had lost capacity
Geometric distortion, Pillow, and picture enlarged horizontaly
The problem was a short from GND to pin 11 inside IC301 (TDA8350Q). This pin is the output of amplifier for geometric correction signal. Replace IC301

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....

Your plasma screen is made up of 1080 verticle lines and now a few of these lines are not working. This is the screen itself and needs replacing.

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.
