Question about BenQ FP71G 17" LCD Monitor

1 Answer

Screen has power but is black

Hi, if i press the power button to turn on the screen, for a split second the benq symble appears, then black. I have pulled apart the screen. it seems there are 3 faulty parts,printed beside these parts on the circuit board are the folowing C826, Q805, and PF801. I have taken the board to a local electronis shop and they don't have these parts, where can i get them and will they fix my problem once they are replaced. Thank you

    Hi ,

    After quiet some looking I found this site ,describing the same symptom that I have .Meaning when I switch on the power I see the Benq symbol appearing for less then a second ,then the screen goes black.I switched to another computer and laptop ( specifying an external screen) , I swapped the signal cable.. no succes.

    When opening the case I don't see any transistor,diode or resistor that looks burned nor any capacity that is leaking or whatever . (Yet I don't have any measurement tool )

    Any suggestion how I can continue my "fault isolation" please ?

    Can anybody provide me the address where I possibly could order a new power board or convertor board for this TFT ?

    Many thanks in advance !

    I will put this in a request form just so Eagle gets full credit where it is due.

    You will have to send an email to BenQ in your country and request the part. They will in turn reply with a yes we can, or try this place instead response.

    visit www.benq.com and goto the support section for the correct contact info.

Looks like many faukty parts on the inverter board.. replacing will not be of much help as it will soon start get troublesome once again. I would suggest that replacing the LCD inverter board is a smarter solution. Hope this helps!
Good Luck!

Brand new BenQ EW2730V not turning on after 30-40 minutes of use with the XBOX 360/PS3. Is it a feature or something because the power button is blinking orange?

Hello,

I believe the power led button is still on while the screen goes black, if yes, it means the picture board of your monitor is bad that is why it appears for a second and goes black after that

Since the power led button is on, It means the picture board on your monitor is faulty that is why it appears for a second and goes black.

The best thing for you to do now is to take the monitor to a local repairer or any service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself in other to complicate issues.

Take care.

Black screen


How old is the computer? Make sure that the power light comes onto the monitor when you plug it in, should be orange and then turn green when video card syncs with it when PC is turned on. If you are getting black screen when PC is powered on:
1. Bad video card
2. Bad video cable
3. Bad monitor
1Solution: Try using a different monitor attached to this same PC and see if it works. If it does, then its the monitor, its cable, or its power supply. If it doesn't work, then its the video card or the video cable coming from monitor.

Blank scren, led stays green for only one second


Explicit enough to see that's this a a repair shop job. That also probably means a replacement- cost of which will not be much more than repair prices. One thing how ever- the power supply[which would appear to be the problem] is this built into the screen [that is does the screen have mains power direct? Or is it powered from an external 'Power Brick' If it is of the Power Brick type - then a new power supply is the answer - get on of the stabilized universal type with a fistful of connectors and a voltage selector switch.
