I've repaired my FP767 just today. It had similar problem.
First of all I thought that I needed to replace CCFL tubes.
Then I noticed inflated capacitors in power supply.
I replaced them all and monitor works as new.

You can try contacting the manufacture or their distributor for service information. Most of the time, these monitors are not feasible to service. In many of these models, the backplane lamps are not able to be changed because of the way the screen is constructed. Very often, the backplane lamp supply also has to be changed along with the lamps.

By-the-way, from my past experience, Benq, as like the other monitor manufactures will not sell service manuals, or spare parts directly. They will tell you that you have to send the monitor for service.

FP767-v2 - 17" LCD Monitor: when you turn it on benq flashes on the screen...


Check the cable on your monitor through video card if there is loose connection. Check also the video card by replacing it with your extra video card if you have. I think the problem is not the monitor but the video card.

No backlight in Benq fp767-12 I have replaced all c5707 on inverter board and fu9024n and few capacitors but it still does not work


If you can expose it, examine the ends of the fluorescent tube itself; if there are prominent black rings at the end, the tube is toast. These cost much less to replace and live only about 4-5,000 hours, much shorter than the inverter board usually lasts. You can buy these from several US sources; the one I recently used was great and the part was $10:

Try checking the cables and disconnect all cables from system and monitor and reconnect all of them.

And in case it does not work,Please change the cable coming from tower to the Monitor as it seems that it has gone bad.


Hope this Help.

BenQ FP767 17" LCD Monitor Problem - Power LED Blinks


Look for small power transistors 2SC5707 near yellow invertor transformers which go to backlight connectors.
But if problem is blinking power LED powersupply capacitors maybe an issue,check visualy and/or replacement.
Also fuse that maybe blown is not glass fuse near mains socket,It is semiconductor black or yellow colour labeled PFxxx near heatsinks of power supply secondary.

Please rate the solution and provide feedback.

BenQ FP767 17" Power but no display?


Different faults here.
First fault is no power, it is bad capacitors on the power board.

Second & third faults are the inverters. (power but no image visible, but feint if you shine a light into the screen)
Check the 4 transistors on the main power board for shorts.

If you are unsure what that means, then take it to your local TV technician, he should be able to solve it fairly cheaply.

Hope that helps.
