This is the common bad capacitor problem. The caps have died inside, and they can be replaced. If you have basic electronics skills, you can go in, order replacement caps, and unsolder and resolder. If you can't do it yourself, you can take it into a shop.

Here is a link to the Cap plague that explains what happens in detail. But I repair these all the time with that symptom.

SOURCE: how do you restart a nec lcd monitor, had power

The power surge probably blew the fuse inside the tv, first check the fuse inside the mains plug, if that is good then you will have to take the back cover off the tv, you are looking for the power board follow the mains cable into the tv and you will find it. Look for a fuse on the board, pop it out of the fuse holder, if you have or can get hold of a multimetre check the fuse for continuity if it hasnt you will have get hold off another fuse, you can normally get them from your local electrical repair shop, they dont cost much and the liklyhood is they will probably give you one free of charge.

I got a similar problem with my NEC 2080UXi. The power led indicator is lit as soon as I plug in power. No back light ever comes on. Capacitors appear to be fine. I did notice that a resistor did burn up and appears to be a small wattage from size of the leads. Does anyone know what resistance R915 is? It's located under the middle heat sink on the power supply board (the brown coloured board).

This may be the solution.

Robb,
The 12V ac adapter could be the bad one. I have seen it was bad before. I don't whether you have a second adapter to test. That is what I am guessing for now, it is adapter because I have seen it happened to my clients before.
Thanks

I Need a power supply for a NEC LCD 65 Series Monitor. The power supply converts 120-240 AC to 12VDC. I don't have a part number as it is not listed in the Owners Manual


Do you have the full model number?
Otherwise try here:

You can get higher current rating but not lower than what it is printed on the back of the monitor but not higher voltage.

The inverter that turns on the back light may be bad - it's suppose to create the high voltage pulses to fire the CCFL back light lamps. Apparently the back light turns on after a few seconds however, it cannot stay on because the inverter might be bad. If you connect a known external CCFL lamp to the to the inverter output you can isolate the inverter.

This sounds like the monitors power supply is failing. (if the monitor is truly right off) Use a flashlight to verify the back-light is not just the culprit. If you can see faint image in the monitor with the flashlight, then this would point tothe LCD inverter is failing. Its most likely the power supply board within the monitor itself. Typically It takes 3 35v 470uf capacitors to fix and a little patience to get apart. Do a bit of googling on "replacing the caps in a FPD1975W" and youll see what i mean. Cheers.

Hi:
Your monitor has a problem on its inverter board. It is an electronic component failure, and often it cost's more to fix it than to buy a new LCD monitor .

You don't really need to replace the power supply, you can repair it by replacing the bad capacitors. I've done it to 2 Nec monitors and it works. However I do not believe its you power supply because you are getting the power on light.

Very common for this model that top backlight globe goes faulty. Can be also inverter PCB fault. If you have couple spare lights connect them to your inverter instead of panel lights and see if fault remains.
