Question about Mag Innovision LT776s 17" LCD Monitor

2 Answers

My MAG Innovision Monitor went blank, only works if I stay connected to internet

Our MAG Innovision Monitor model 900P manufactured 11/2005, purchased 3/2006 goes black if we disconnect from the internet this started in 8/2006. In order to get the monitor to work we have to turn the computer on and off several times and press the button on the monitor and keep pressing it over and over and over for like 30 min after doing this we have gotten it to work again with a full picture. We then connect immediately to the DSL internet. We notice that if we close all internet windows, the screen will go blank in an hour or so, and could only get the screen to work if we pressed the monitor button on and off again for like another 30min. and we had to then connect to the internet to keep the screen working. So we started keeping the computer & internet on 24/7. Last night the internet window screen started clicking and pulsating, but we still had a picture so we decided to close the internet window. The screen now goes blank, and we can only get the screen back for a half a second and it keeps going blank. I have now connected our old monitor, not a flat screen and it is working fine, I have connected to the internet and then tried hooking up the MAG flat monitor again, and we now can't get the monitor to work. I saw the other positing where a person had the problem of their MAG monitor going blank and it was suggested that they check out the bulbs or one other thing. Does anyone know why the monitor would continue to work if connected to DSL internet and would go blank if we disconnect from the internet? Now we can't get it to work at all.

    This is a MAG LT916s 19" monitor. All of a sudden the screen goes black after being on for 3+ hours the screen goes black but the green power light remains on. Shutting off the power switch for a couple of hours and then turning on the switch powers up the monitor and it works fine for another few hours before going black. Could it be heat?

    Same product number and model as above but mine will only stay on for about 45min before going blank. Have to let it sit 'off' for a while before you get another 45min of use.

    My Mag monitor will not stay on for more than a few seconds. When I turn it off and on again it comes on for another few seconds and then shuts down. This monitor is less than a year old. Help!!!!

    My monitor is a LT 716s plat panel MAG Innovision and it goes blank when turned on. The screen turns black but it remains on. I have to turn it on and off in order to see my screen for a half a second before it goes black again. How can I check the bulbs. The back of the screen will not open up. Any suggestions?

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.

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)
It could be simply a bad connection on the wiring harness that connects this board to the lcd panel
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

Check and make sure that the speakers and any power supply (UPS) are not placed very close to the monitor.
