Hi.
Generally an all white screen scenario is caused by no signal from the monitors video board getting to the actual screen.
It could be as simple as a disconnected ribbon cable that mounts the two items.
It could also be a fuse on the back of the actual lcd screens circuit board. These fuses are usually labeled F1.
If you have a tester and the capabilities, in normal running mode the screen should be getting around 5 volts dc at this fuse.
The other problem could be a bad video board. These are not always repairable.

I have a MAG innovision 900p 19" monitor that turns white everytime it is turned on.. I've tried cleaning the dust from the connectors and have tried turning it on and unplugging it. Nothing I can think of...


White screen means that the video signal is not getting from the vga board inside the monitor to the actual lcd screen panel.
It may be a bad vga input board (also called a main board)
OR
It could be simply a bad connection on the wiring harness that connects this board to the lcd panel
Or
it could be a blown fuse on the board on the board that is permanently mounted to the back top of the lcd panel.
I would check the wiring connection to the lcd panel inside the monitor first

Hello,

The white screen is caused by the power supply board not providing the correct voltages to the display driver board.

If you don't want to do the repair we do offer a repair service for $35 plus return shipping.

I hope this helps, If so please rate our solution.

Black screen


It is most likely that the filter capacitors on the power inverter board have failed. I took mine apart and found seven swollen capacitors on the this board, they fail prematurely and seem to be the only thing wrong with the unit. I replaced them and now it is working just fine.

six 470uf 25v electrolytic capacitors and one 220uf 25v Capacitor.

you should not attempt to repair this yourself unless you have some electronics training since there is a shock hazzard involved and also these capacitors will blow apart if they are installed incorrectly (very messy experience).

Mag innovision LT716s monitor


When I turn on my computer the monitor takes a long time to warm up and colors change and vertical lines flash across the screen from right to left before the screen becomes normal again. Now the power light even goes out upon turning on my computer and I have to unplug the video cord and plug it back in to start the screen back up which even takes longer.

MAG L765b Model 780


Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!
