Question about BenQ FP71E 17" LCD Monitor

2 Answers

Power but no picture

My Benq monitor stopped working, I tried turning it on twice and got the logo twice. Then went to search up the problem came back and tried to turn it on again but their's just the green light and no picture. Not even the logo.

What could be my problem?
I have a Benq FP71E monitor that brings up the logo when turned on but then the screen goes black. Once in awhile I get a quick glimpse of my desktop but then it goes black again so I can't use my computer at all. Sometimes if I turn it off and on several times it will work but that doesn't even happen anymore.

    Hello,
    I have the same problem with a Benq FP71E+ since 2 days. After some trials with the on-off button it got him to work but problem reoccurs when rebooting.
    The monitor worked well before for ca.2 days. My computer is nearly new so I think it is not the graphic card.
    Best regards
    Claus

    I have exactly the same problem with my BenQ FP71E. But when I took it into a pc repair store, it worked fine for them, got it home and it was black again. Power light is on and I get the BenQ logo, then nothing. Tried new cables, etc. but it still does it. Anyone have a solution?

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...
