You have a failed inverter circuit. This is a very common fault with BenQ and other LCD monitors. I have seen more FP737 and FP731's and all their cousins in the last 2 years then I care to count.

You will be best to take it to a TV technician and have them do the repair. There are ways to fix it yourself, but the chances of success are not great without a decent amount of electronic knowledge.

Call several places and get approx quotes based on the inverter fault. A lot of TV techs will not work on LCD monitors and is another good reason to call around first.

One final thing, check the manufacture date on the back of the monitor, these normally come with a 3 year warranty and it will be either expired now, or very close to it. If it is still under warranty, then contact BenQ near you to facilitate the repairs.

I have a samsung 17'' lcd monitor.when i power on my monitor without data cable i got a message on screen CHECK SIGNAL CABLE.when i connect data cable my lcd is going to power off.please help?


The message says that the monitor doesn't receives signal - which is normal. Since the problem appears only after you plug in the cable in means that the problem is located there - something is wrong with your pc, most likely the video card has died.

What does it mean by dead cells?


I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

Turning the power on causes the screen to display ENVISION for approx. 1sec.and it goes out and stays out. Switching a display signal on through an A-B switch gives approx. a 1sec. display time that does...


Your power supply has burnt out which unfortunately is extremely common in new devices. I do agree that it may be worth fixing if it is only couple years old.

My aoc lcd monitor appear full white screen


Most probably failure in the LCD controller IC in the lcd controller board. that no signal was sent out to the lcd driver ic thus you could only see white display on the screen. A replacement of LCD panel might be the solution. regards

On Pwr up logo appears then LCD returns to stanby Black screen


I will assume the monitor is staying on during the boot process all the way until Windows loads.
If that is the case, then...
  • Start the computer
  • wait until the initial bios/logo screens for your motherboard go away.
  • Press F8 to get the Windows recovery boot menu
  • If you see the Windows Logo you would normally see then press rest and try again.
  • In the recovery screen, select SAFE MODE
  • Boot into Windows and uninstall your video card.
  • Reboot the computer the normal way through the start menu.
  • When your PC starts back up it should then reinstall the video card, and set itself automatically back to 60khz as default.
Let me know how you go =)

INPUT SIGNAL OUT OF RANGE


some how your screen resolution has changed above or below what your monitor can display. you need to boot your computer using another monitor that can work with the resolution your computer has switched to(i used a spare crt monitor when it happened to me) change your resolution in display properties to a normal level like 1027x768, and while the computer is on swap the monitor cables to verify the lcd is working.
It is perfectly safe to unplug the video cable and plug it back in while the computer is turnned on.

Sounds like the invertor board in the monitor is bad or the LCD screen has had it and needs replacing.
