I had a white blank screen issue and sent my BenQ FP757 monitor in for service. It came back after a few days with a little problem. I just cant seem to get the standard combination of blue,red and green to set my monitor display to normal. Its either too red, or green or blue. I have tried using the sRGB option and also tried setting the R, G and B components to 50,50,50 too (as is on a colleagues monitor)but still cant get the optimum setup. Any suggestions?

I have had this problem before and had to contact the manufacturer. I was able to send them back and the manufacturer sent me a replacement. If your monitor is under warranty it should not cost you anything.
You need to open it up and inspect the PCB for bad solder connection or over heated components. BenQ made monitors for Dell, so look at some pictures of failed Dell monitors here to get some ideas what could have gone wrong with your monitors, post back what you see so we can guide you further: http://s807.photobucket.com/home/budm/allalbums
the vga modul can't tobe start power "on",power regulator/switching normal condition. some of the semiconductors on board of the VGA modul ( transistor ) is Shock/dead. I need schema/diagram of this,please........
When you first switch on Does it show Benq?If not the inverter circuit has failed.If you are technically able you can try resoldering transistors on inverter board.If your display is black all of the time transistors could have failed as also related fuse etc.
And yes please check with BenQ Normally these have a 3 year warranty.
If it is still under warranty from Benq (3yrs), call them for a return. I have one (FP731) and did the same thing. There is an IC within the monitor that is bad. Pretty soon there will be nothing on the screen.
Dor, BenQ has a 3yr warranty on their monitors. I would contact their tech support and receive an RMA to return it for repair. It will cost you shipping out there but they will ship it back. I has a BenQ FP731 myself and it blew a capacitor inside that allowed the screen to stay on. Fixed it and had it back in 5-7 days. Good luck.
