I have had this screen for 2 years now. One day, it stopped working...
The screen is blank and the LED is off. If I press the power button, the screen displays a BenQ logo and the front LED turns on (green); 1-2 second(s) later, the screen is blank again and the LED is off...
I have tried a different graphix card, a different computer, a different VGA cable and a different power cable.
I hope someone can help me...
Thank you very much
I hope I have been explicit enough

Re: Blank scren, led stays green for only one second
Explicit enough to see that's this a a repair shop job. That also probably means a replacement- cost of which will not be much more than repair prices.
One thing how ever- the power supply[which would appear to be the problem] is this built into the screen [that is does the screen have mains power direct? Or is it powered from an external 'Power Brick'
If it is of the Power Brick type - then a new power supply is the answer - get on of the stabilized universal type with a fistful of connectors and a voltage selector switch.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.
Most likely your video card is broken. To check if the motherboard isnt broken either, I would suggest you test usb, sound, and other features of the motherboard.
If your motherboard isnt broken then you have to buy a "pci-e graphics card" at your local store. Shouldnt cost much, about $40-70. Hope that helps.
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.
