Having problems with your NEC AccuSync LCD71VM 17" LCD Monitor ?

After three seconds power it on the back light goes off. At this point if the display is turned off and on again, the image gets back and gets dark again after three seconds


Answers :

There seems to be bad solder connections either on the power supply or the inverter Board. You may even have a bad capacitor on the power supply board. When caps go bad sometimes the yswell at the top of them, if you take off the back cover look for swollen capacitors in the power supply. The inverter board has small inverter transformers on it, check for bad connections on it, caution tho this board has high voltage on it. One good way to check the inverter board is while you have the back off. Darken the room as much as possible, even total darkness is good and turn on the monitor while looking at the inverter board for small arching or sparks, if you see any then this is your problem area.

My monitor only comes on for a few seconds and then goes very very dark, although the content is still there somewhere.

Unplugging the power lead from the back and utting it back in again will relight the screen for about two seconds before it all goes blank again.
