How to remove power board from MAG LT782S Model 700

Is it a really fast blink on the power light? If so, you might be looking at the wrong item. The fast blink means that the mainboard has an issue.

Like I've said sever other times on this board, there's an NPN transistor that is usually the culprit. Just yank it and replace it with a Radio Shack NPN and you should be in business (maybe bump it up a touch so that you don't have the same problem again).

you can find one at zp-electronics. it's an is-034 cord.

probably capacytor problem in the mainboard, take it to the lab it will be cheaper then buying new one

SOURCE: I have a monitor MAG LT782s. Backlight works, but

HI There,

The easiest way to troubleshoot this one is to borrow another monitor that you know is displaying properly on another computer and connect it. If you're still not getting video then it's almost certain your video card has failed.

This means that the power supply board has a problem. The problem is that the part of the circuit that controls the backlight has failed. This is usually caused by capacitors that have gone bad or transistors that have shorted.
