    Same problem with our NEC plasma. I was able to briefly get it to display "Video1, Video 2, Video 3" but when I got it onto the source "Video 3" (which is my satellite), the image appeared for a fraction of a second then the monitor shut off and continued to display green on the LED indicator. Could a lightning strike have caused this type of damage or is this a common occurrence after 4 years of use?

    I believe we have the 42 in. NEC and have the same problem.
    I got it to display Video 1, Video 2 and when I got to my source Video 3, the image blipped on the screen then disappeared as the monitor clicked off. The LED continued to display green for "on" but the screen was definitely off.
    Tried unplugging the monitor for >5 minutes then re-plugging. No change.

    Can a lightning strike cause this? Is it normal for a monitor to do this after 4 yrs of wear? Anyone had this repaired that can let me know how much it cost?

    I also have the same fault but found the tv will only go onto a standby state with an empty signal, but as soon as its in a standby state only repeatedly switching off and on will prompt it back to life, my display is very dark. I wondered if the relay had gone on the psy board?

You should take the monitor to the NEC service rep for your area.

This monitor is service with board exchange. They will try the modules to determine the fault, and then do the factory adjustments to match the module.

By your description, it is most likely that the fault is on the power supply and or the panel drive module.

This TV set will be on the expensive side to service. If the display was having good emission, it may be worth to invest the money in to it.

Won't power on

you need to check the supply outputs. unplug the panel from the supply and check with an anolog meter. if the supply runs for 10 secs it will lock out.
or u could start with the resistors and FETs in the supply.

NEC PX-42VP4DA Won't stay on.

It may not be the power supply. It can also be another board/module that causes the PS to cut-off.

Service manual

You can search this database for the service info you seek about your tv here:

Most service manuals with schematics cost about $27.95 for the PDF version of it, otherwise the paper version is about $15.00 more for handling and shipping.

You will need the chassis number of the unit in question in order to search for it. I hope this helps!

Good Luck!

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.
