Your description of the problem indicates that there is intermittent fault with the backlight circuit and components of the screen. Open and verify the devices and circuits that are associated with generating light from the device end towards the source of driving circuit. The fault may be detected lying in between, as a loose connection or dry joint. Device failure will hardly give an fault that occurs intermittently but a loose connection, dry solder joint or temporary partial shorting of circuits by some loose and strayed conductive substance.

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

SOURCE: NEC PX-42VM3A 42" Power problem

I have read that this has been fixed with little more than a hard reset. This means just unplug your set for 10 minutes or so and let all the power seep out of the boards and capacitors, then plug it back it.

If that didn't fix it, your unit needs servicing. If you are handy here are some troubleshooting steps:

Check the fuse at Y-Sustainer pcb.
If blown do not replace. Look instead at scan converter boards. They are connected between y-sus & plugs from display (left side with face down, back open). Look for signs of 'burning' at upper and lower long boards. If any imperfections are found, replace all three boards: Y-sus, up & low scan.
If fuse was okay, check power supply for bloated capacitors (big board in middle of set).

I hope that helps.

NEC 42mpi plasma tv not working


Check the +170 volt  test point on the power board (not the power filter board, the one that the plug comes into) but the one to the right of that board. It has a 5v test point (TP +5v) , a +170 and a +70. I've found that the +170 transformer goes bad, and won't allow you to adjust the voltage using the pot screw.
