    I Have Benq FP371 LCD and the failure is No Picture at all only power botton was green.

    I disassymbled the LCD and found one bad transistor P/N C5707 and I already replace a set Four (4) transistors which controls the inverters...

    When I turned the on/off switch on, the back light flashes on the screen for a spit second.

    I measured the high tension to the lamps, it is also noticable for a split second.

    I checked all the transistors on the perimeter, they are all OK.

    Do you have any more suggestions to solve my problem?

    Kind Regards

Change the 2SC5707 transistors and electrolytic caps in the inverter
section. Also check the 3A picofuse, and resolder all transformer

The only solution I've been able to find for this is to turn off the computer for a minute or two and reboot, while rebooting, it is important to keep the mouse moving so the arrow on the screen moves. This should provide a temporary fix, I'm unsure about a permanent one.

Benq fp581 screen goes blank after about half a second evertime i turn on my computer.

Even thought the monitor looks blank check to see if you can see a faint image (shining a flashlight at the monitor sometimes helps). If you can see an image it could mean that the inverter board has gone bad.

I have also heard of an overheated computer causing a similar problem.

Logo appears then a blank screen

You need to open it up and inspect the PCB for bad solder connection or over heated components. BenQ made monitors for Dell, so look at some pictures of failed Dell monitors here to get some ideas what could have gone wrong with your monitors, post back what you see so we can guide you further:

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.
