NEC PlasmaSync 42MP3

Recently my Plasma has been displaying a range of flickering red and orange pixels across the whole screen when I turn it on. After a while they disappear 1-2 mins. Turn it off and on again no problems. If I turn off and leave off for about 10 minutes plus it happens again! Even with no other signal source attached to the plasma I get these symptoms! Had the unit for 4 years - was thinking of getting a technician out - thought I'd try a post first - :-) Any help appreciated!

    During warmup (for teh first few minutes), the top 4-8 inches of my screen has these green and yellow vertical lines mapping with the image in that area.

    After a few minutes, the image is fine.

SOURCE: NEC Plasma Sync 42MP3 Problem

Hi, This model has some design flaws and yes NEC admitted to them a year ago. The problem with your monitor (hopefully) is a bad power supply. Have a Tech with a voltage tool check the boards as well as the connections Reason, this monitor generates a lot of heat ( no cooling fans) primarily at the power supply and sits there. So the wires tend to go weak by the heat build up. What the problem is the power is not going to the correct board in the right voltage. hope this helps out!!!

Its NOT a TV, its a display. It does not have its own TV tuner or RF converter. You have to runit from a VCR, A DIgibox or SKY TV.

I dont' have the fix but I do have a work around. You can hook your source directly up to a surround sound unit if you have one using red and white audio cables to the aux input on the surround sound system.

Exactly the same problem here on same model NEC but problem more intermittent, some days can be fine others unwatchable. Can see many dark pixels when i lose brightness, looks a bit like a big square patch over the screen. You ever manage to fix this gemguy?

NEC Plasmasync 61mp1 - won't turn on

Its the power supply board. If you cant get the whole board, check your transistors theyre most likely FSXXX-X (part #). Replacing them should solve the problem. And they're only about a dollar each so youll save a bunch too but it requires a little more work.

Hi Gemma - have a look at this forum - it may be similar to what you are experiencing. http://forum.eserviceinfo.com/viewtopic.php?t=5411&postdays=0&postorder=asc&start=0 Things don't look good for NEC owners I must say! Good luck Saty.
