NEC Power Supply Problem

I saw your post at http://www.fixya.com/support/t15374-nec_plasmasync_42mp1 and you said you replaced some parts. I was not sure if you had a 42mp1 or something else. What model did you fix? Is the part number on the power supply board PKG-1720? Do you have the parts designations for where it is on the board (something like Q527, etc.)?

Thanks,

Fred

We were given this tv and don't know if its digital or analogue, will we need a set top box?


This tv is capable of both digital and analog settings. It is however recommended for use with digital components. You can reference the manual at necdisplay.com. This should be a helpful reference with setting up your newly aquired NEC PlasmaSync. Have fun with it!

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.

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.

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.

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.

Service manual


Hello,
You can search this database for the service info you seek about your tv here:
http://www.samswebsite.com/photofacts.html

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.
