Power issue NEC PX-42VM5A

I have three NEC 42" Plasma's: PX-42VM5A. Two were working a year ago when uninstalled and put in storage. Now all three behave identically and do not work:
When power button is depressed, there is an audible click (relay) the power light turns green, a few components hum then another identical click and power light goes red. A couple of times I was able ot get a glimmer of a picture on the screen, but no longer anything.

After reading earlier suggestions it seems the power supply board is likely faulty. New ones are $300, which seems to much to spend on a four year old Plasma. Anybody have an idea about what component on the power supply would be worn out?

Any insight would be great. Thank you,

Les

Most likely a transistor - NEC used FSM series for a while which are now discontinued. Let me know if you need info on how to find/tell which parts are bad.

    MOSFETs used for high speed power switching are bad causing an overheating problem. Use an ohm meter to find the ones with inconsistent readings.

    This is often the culprit for SONY, Panasonic, NEC, Pioneer TV's not powering on. along with capacitors these components are the problem to almost every faulty electronic

SOURCE: Any idea if I can hook my laptop up to my EDTV?

Yes, if your laptop has a VGA out port (that is the external display port - usually blue with 15 pins).
The NEC display has a VGA input on the right-hand side.
You just need a VGA cable that you plug in both connectors.
Then, read your laptop manual to determine how to activate the external display (usually the FN key with an other key that has a display icon on it).
On the NEC display, make sure it is using the RGB1 input (use the remote to activate this input).
That should do it.

NOTE: Make sure your laptop is using a reasonable screen resolution (that is 640x480 or 800x600).

Power supply issues


hi there, i recommend replacing the entire board. once you have a short like this, the micro board itself will become useless. the thin micro circuitry has become separated within the layers, preventing a closed current transfer. its best to order a new canvas so to speak.
