Mag monitor lt782s - green light on screen black


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.

With the SECOND (usually the RIGHT) mouse-button, click anywhere on your computer's "wallpaper".
Click Properties.
Click Desktop.
Click Identify and watch both screens.
One should display a large '1' and the other a large '2'.
Click 'Extend my Windows Desktop onto this screen".
Again, click Identify.

Power supply, replace the caps, 220uf,470uf,680uf. you will see the tops of them are popped out, check the board too see if its turning color from the surface mount transistors that drive the lamps..If its turn an very dark color the parts have been very stressed out..

After display goes black monitor green power light remains ON. Power can be turned of and the display again stays on approximately 5 seconds. Replacing capacitors in power supply did not correct the...


The problem can be the lamps are bad, the only way to tell is to remove the lamps, look for poor soldering works where the wires are attached to the lamps, bad lamps will have very dark color at the end of the lamps, just like bad fluorescent lamp you see when it is worn out, anoher sign of bad lamp is pinkish glow when lamp si first turn on. The transistors and caps are good in the inverter section?

Screen goes black after a few seconds.


when the screen goes black shine a flashlight on it. If you see a dim image the back light needs to be replaced. Otherwise check the inverter as that may be causing the problem as well.

I think it's busted


you need to open the case and check the capacitors and if they seem doomed or color is leaking then replace the bad ones that should stabilize the power to the vertical ic chip
