Question about Computer Monitors
My MAG Innovision Monitor LT1919WDb goes blank. One day i was on the computer and the monitor flickered and went blank. I turned it off and on again. It came back but within a few minutes went black again. Now it will only stay on for seconds and go black. It worked fine for almost a year.
When a monitor works for a few seconds or more and goes black it is a problem with the power inverter board over heating because of a bad capacitor or capacitors that are not the right size. There is no problem with the VGA controller since it shows video for a few seconds. I have fixed a lot of Mag LCD monitors with changing just two small capacitors for $0.50 a piece and some of my time to solder them in. Less time as i have gotten better. You can buy the capacitors on Mouser Electronics Online. Just make sure they are the right size and dimensions. I have one of these monitors on my table now and have not determined the exact capacitor that is the issue. I have change five out and it is still doing the same. Four more to go. None of the capacitors looked bad, thus the prcess takes longer. Good Luck

I had the same problem. I contact the manufactuer and they refused to fix it. They said it would cost an additional $100 to have it fixed. I have not even had it a year. I thought products sold in America were suppose to last longer than a year? What has happened to companies standing behind there products. Beware of this monitor!!! DO NOT BUY IT!!! LT1919WDB

I started with C11 and C12 (220mfd 25volt) just to get it to the 3 second shutoff. I'm still chasing the rest.

Screens going dark are in most cases the result of burned out components on the power board or inverter board.
Some parts on these boards have life expectancies like light bulbs do.
Some of these are repairable. I've done several MAG innovison models, But not this model yet.

I have the same problem. This isnt really a solution, but I turned my monitor off, then held the power key to turn on for about 10 seconds, and it has been working fine. It has only been on for a few minutes, and it is more than likely a temp fix until you can get it repaired or a new one.
