Question about BenQ FP71E 17" LCD Monitor

BenQ FP71E turns off after 2 secs- Logo flashes then turns off

This has suddenly started today. I notice that the screen had turned off. At first I thought a power cable was loose but this was not the case. Pushing the power on button on the front of the unit -- the light turns blue for about two seconds -- the start-up BenQ logo on the screen flashes up then the unit turns off.

It has never had problems before.

LCD monitors behaving in this fashion more than likely have a faulty inverter. Refer www.lcdparts.net for solutions.

I have two of these monitors and they both failed with 4 weeks of each other. Read on another site the guy went around the circuit board tapping all components with the handle of his screwdriver, it worked. This indicates to me a dry solder joint. So will try with mine, bit by bit and see if I can localise the offending parts.

    These monitors have a power supply sub board that takes the mains power. Power supplies are always the hardest working component of any system. I replaced the sub boards, all fixed. Sub boards are available from BenQ.

Have the exact same problem as well. Pulled it apart and the capacitors seem superficially okay. Not sure what to look at next.

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: http://s807.photobucket.com/home/budm/allalbums

Check to see if the video cable is connected at both ends securely.
Also, if possible, try another cable.

Power but no picture


Try to re-solder the inverter part of the board. You may recognize that part where the 4 connectors from the backlight tubes can be found.... usually the small transformators (sorry, my technical English is not good) have bad soldering eyes after longer use. This may work if backlight turns on for a few seconds, then the power led is still alight but screen goes dark.... the inverter then "thinks" one of the tubes might be defective and turns power off. Hope this helps a little...

Monitor Randomly Turns Black


I have exactly the same problem with my Benq FP71E+ ..

What i found is a temp fix is this :

When monitor dims and goes black i turn it off , hit the bottom left side (near the BENQ logo) turn it on again and it works ..

This works every time for me . But after a while it switches off again , could be 5 minutes could be 5 hours . Its random

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 =)
