Question about BenQ FP731 - 17" LCD Monitor

1 Answer

BenQ FP 731 17" black LCD

I had turned my monitor off leaving my computer running while I slept. A friend tried to use my computer while I was in the shower, and I'm not sure what he did, but now the monitor won't display anything at all. He said he didn't know what button to push to turn it on, tried moving the mouse, thinking it was just on the black screen saver, but when that didn't work and he couldn't see anything, he thought the computer was off, so he pushed the button and shut down my system. When it started back up, I can hear it boot up, and the windows sounds come through the speakers, so I know things are starting as they should, but the green light just blinks on occasionally, and otherwise, there's no indication of life from it. Is it in some sort of standby mode? Did he change something I need to fix with a combination of pushing buttons? Is it shot? I've tried connecting it to my laptop and switching over to external video, and nothing happens, so it's the same with two separate PC's, my Dell Dimension 2350 and HP Pavilion laptop.

I hope I don't have to buy another one as I'm on disability and little money.

    My monitor has the same symptoms as described. When I shut down my computer and turn the monitor off and then restart the monitor remains totally black. I finally unplugged the monitor from the computer and from the wall then reconnected and it came on immediately and works fine until I shut down again. Is it the monitor or the video card?

It sound like power on the monitor if it is this what you need to do.

Change the 2SC5707 transistors and electrolytic caps in the inverter
section. Also check the 3A picofuse, and resolder all transformer
pins. Are buy a new inverter board,this brand of moniyor is a Dell monitor.
Hope this help you.

Trying to purchase a power adaptor for benq fp781 can only find one compatable for fp 791 would this work on a fp 781 monitor ??


On the screen itself, where it plugs in, it should give you a voltage rating, and a line with a C encompassing a circle. Make sure that these two things match up between the two screens, they should, but at the same time, there is the possibility that they don't. Also, make sure the plug is the right size. Yes, it should work, but I would just take the extra precautions listed above to prevent frying your monitor.
I hope this helps!

You normally don't need any drivers for LCD monitors. The resolution should be 1440><900 or higher.

Try connecting the monitor to a different computer, e.g., a laptop.

The power-cord to the monitor seems to be OK.

Check the "data" cable between the monitor and the computer -- try a different cable.

With the monitor turned on, restart your computer, and watch the monitor. The computer should show some start-up messages (white text over black background), followed by the Windows "splash" screen. If it does, the monitor is working correctly.

The vertical lines/bar are sign of bad T-CON (LCD controller driver) board is bad, it is part of the LCD panel assembly, new screen will be needed, not worth it. You may try reseating the ribbon cable at the panel.
