Question about NEC PlasmaSync 42MP1 42 in. Television

1 Answer

Won't power on

I power on the 42MP1 and the green light comes on, I hear a click which sounds normal to me then the light goes to red after about 2 seconds. I talked to a tech support agent at NEC and he said that he couldn't help me because I am not certified, but then suggested that it was a short in the panel. He said to disconnect the panel and see if the light stays green for 10 seconds. He seemed so vague and in a hurry I am concerned that his recommendation is not correct. Do you agree with the Technician?

I have repaired many monitors but before I take it apart I want to have as much good info as I can get. Thanks.

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.

Power Issue


Now,u plug in the tv u get a solid red standby power red LED light in the front of the LCD panel right?When u push the power button on the remote u hear a clicking sound?Only one clicking sound,not the power supply board problems.It the Tuner board problems.But u can make sure it the power board problems or not.By taking the tv aparts check the power board,that board where the a/c power cord goes into it.Look all around the power supply board check for these leakage capacitors,they alway bulges up it top or puff up it top.No bad leakage capacitors,then it not the power supply board problems.

How many times red light blinks? It is error code of problem in TV.
There would be pause of 3 seconds between blinks so count from pause to pause and let me know to find out solution.

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.

NEC PX-42VP4DA- Won't stay on


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.
