Question about Mag Innovision LT765b 17" Flat Panel LCD Monitor
My MAG flat screen monitor recently begun to flicker after 5 min.s of use, til the screen goes crazy (gets all "jumpy"), and I have to shut down. I have to wait a day or so and try again to get 5 minutes out of it, so it's virtually unuseable at this point. It's less than 2 years old. I also can't get the vga cable off the back where the "DC IN" slot is, because it's impossible to turn the connector to loosen (wrench won't fit). I noticed this because I tried to hook up an alternate monitor to verify whether the problem was with the monitor or with the CPU... it's the MAG monitor!
Any idea what's going on, is my monitor already dead?

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.

Hi this is the way how to examine
what's wrong with your monitors. After you turned it on and the screen went black, you have to check that if you can see the image on the screen or
not by shining a flashlight into the screen, not directly but find the best
angle to the screen and take a look very closely. If you can see the icons or
any image, there will be a minor problem. This is because of the lamps inside
screen. Some of them were broken and it is very easy to replace. If you cannot
see anything on the screen, there'll be some problems with inverter board. If you
have soldering tool and want to fix it by yourself, check the caps first. It
may cause this problem. Some caps might show leaking or burn spot on the board
because of too high temp. If you don't have soldering tool, you better go get a
technician to do so.
Hope this help!! If anything I can help you with, feel free to let me know.

usually this problem is caused by a faulty inverter circuit. transistors might been running too hot or a leaky capacitors also.not an easy task but try looking down for any defects on high voltage sections.

the monitor has bad backlights or circuitry. Call the company, their number should be in the owners manual. Or, look on the web for their website. Or, call the store where you bought it. The monitor must be taken to a service centre for repair.

Beautiful screen, lasts about for a few minutes, goes black. Power button still green. If I turn it off, and then back on, it works again for a while. Any ideas?
