MAG innovision LT917s problems

Ya, i haven't seen any real answers to this around here so here you go. I have the monitor mentioned above^^^^ and i was wondering why its doing what its doing. When I start my computer and have my monitor on the screen stays black and the green power light is flashing on and off. It has not really been that bad until today when I had to sit here for literally 20 full minutes until my picture finally came up. I restarted my computer entirely after turning the monitor on and off a few times to no avail so I just continued to wait until it came on. I am running Vista on my new machine with a brand new nVidia 7800 graphics card and i found out that its not the computer. When I used this monitor with my original PC it did the same thing for less periods of time, much less, like 30 seconds at most. I am a busy college student and sometimes dont have time to wait for 20 minutes for my monitor to turn on properly. If you could please answer as fast as possiple I would appreciate it I am very sick of this monitor and its only a little over a year old.

    I have the same exact problem too. I messed around with a bit and got it to turn on after about a minute, but now the screen just stays white, I checked all the connections and tried all the different possible connections for it inside and I still get the same thing.

K I just fixed mine! I hope you still have your screen dude. Its easy. Take the screen apart, and take the monitor part off, open up the part thats attached to the back, and remove the big silicon peace thats attached with the golden bolts. Look at the capacitors, if they are bulged up then they are broken, go to radioshack and buy some new ones, they are 470uF 25v 105C, but 470uF 35v and 85C will work as well. Solder them off and put the new ones on, connect everything and it'll work like new. Just did it today and saved myself 200 from buying a new screen!

I repaired the same problem and had 6 of the 470uF, 25V, 105C caps that had bulging tops. I replaced them with Digi-key 493-1549-ND parts. I also had a 220uF, 25V, 105C part that had a bulging top. I replaced that one with a Digi-key 493-1826-ND part. The monitor works like new after the capacitor replacement.

Even though it is a fairly new monitor, I would say that it is defective. It is possible that the refresh rate for your computer is too high for it, you could try setting that down to a lower level, and see if that works. Otherwise, probly a new one is in order.

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
