HP LP3065 monitor turns off and won't turn back on; is this a Windows problem


It doesnt sound like a windows problem. A simple test for this is to unplug the vga or hdmi cable from the monitor then turn it on if it has power it should say no signal. Also try either another power cable to the monitor or change the fuse. Hope this helps.

The monitor goes blank after a few min, it comes


Are you sure that your computer isn't just going into power saving mode? Not sure what operating system you have but go into the screen savers tab or video properties and find out how your system is set up for power saving It may be starting before your screen saver does so the monitor would just go black.

Screen Goes Blank


Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

Monitor show picture for a few seconds, then turns black


It sounds like the power supply board on your monitor is failing. If it's still under warranty you might be able to get a replacement from the manufacturer - if not, you might be able to have it repaired at a computer or TV repair shop.

Monitor going black


HP's are known for bad capacitors in the power supply.
Replacing them is simple if you know how..not so simple if you don't.
Try your local TV repair centre. It should not cost alot to have the capacitors replaced.

Hope it helps =)

Screen displays fine for a second, then goes blank


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.
