Question about NEC PlasmaSync 42MP1 42 in. Television
I saw your post replying to somebody who had a problem with their 42MP1 NEC not staying on. I have the same issue with my 42VP4DA- I turn it on ad I hear a click, the light goes red--> green then it clicks off again after a few seconds. I have been able to see the menu prompts for a few seconds while this is happening.
So far I have only tried unplugging the unit. There are no authorized NEC centers here in NH and it sounds pricey to get it repaired by them anyway.
What would you recommend starting with on my model? Do you think this sounds like a power supply issue or a scan board? If you think it's the power supply, would you know how I can check this with a multimeter?
Thanks for any advice you have as I am not ready to junk this tv if I don't have to.
Yeah, it's the power supply. I've ordered (2) of these power supplies used, and the same problem seems to be happening with both. The transformers on the power supply board (namely, the 170+ volt one) are the problem. You have several test points on the power supply board which you can touch with a voltmeter to see if your television is getting the correct voltage . Mine made a a high pitch squeal which indicated which transformer was bad. If you find a place to get the transformers new - id like to know, because mine is still non functional because of this and the fact that a new PS board is over $600.

The transformer that is making a loud noise and that is not working properly with my monitor is the 70+ (EC-1180 or PC40 9Z19 Z). I can't find the transformer or the PKG 1720 PSU. Help!
