    It seams as though the back light has given up the ghost as I can only see the screen if I shine a bright light into it.
    I am having a problem opening the LCD Case at the moment I have taken out all the screws but can't open it and I don't wish to force it so what do I do now or more like what am I doing wrong ?.

    Regards Steve.

The parts list..Here we go again =)

  1. 4x 2SC5705 (can also be 706 as well)
  2. Bridge capacitors (near the transistors) - Replace
  3. Transformers (can be either 4 or 2 used) - Resolder
  4. Fuse link (Marked with prefix FBxxx top middle of the board) - Replace
  5. 2x Diodes (close to transistors, one for each pair.) - Test
Start with those and if you still have issues post back with a photo of your board from both sides.

I'm trying to set up BenQ FP71G+ as a second monitor connecting to Nvidia GeForce 8800 GT. I cannot get the BenQ to display even if it is the only monitor connected. However, I can see the BenQ in...


I have had problems occasionally with connecting a second monitor, too. Hook up both monitors. In the Windows control panel, look up display (or right click on your desktop and select display). Is the second monitor shown? If not, click "detect" and see if it shows up. I have had a couple times where I clicked on the monitor icon in "display" and then clicked "enable this monitor" and it started working. If not, then try switching the cords so your working monitor is the second one. try again and see if it show up. If not, the problem is probably with the video card or video card driver. Try and update the driver for your card.https://www.geforce.com/hardware/desktop-gpus/geforce-8800-gt
If this does not work, the issue is probably the card.

No display, screen is blank even compuer is running


Can I assume (?) you re-tried firmly checking each cable connection and the power supply is soundly in place including checking the fuse in the plug That's all I can suggest as the things I would do if in your shoes.

Check the ribbon from the video card to the back of the panel. It has to be aligned perfectly and locked down in the right position at the video card side, and pushed in corrctly to the panel.

The section that contains the inverter circuit is totally seperate from the rest of the power supply. Seperated by the fuse link marked FBxxx.

Monitor doesnt work


Replace 3A PF### fuse on main board. (reason for the # is because I have put the monitor together and cant remember the component number) I could see with a torch the initial display on power up. The PCB has white writing on it to display what component should be on the board. All PFs on the board have wire links on them but one. It looks Iike a black cylinder, 7mm long, and 3mm diammeter. The green writing on it was "bel MS 3A". I would have found this fuse earlier, but the writing was facing down on the board. This fuse powers the circuit to the back lights. Please check continuity of fuse before replacing back lights, as a 10 cent fuse is cheeper than backlights.
Fuses WILL blow for no reason. I have replaced it with a 5A for testing, and everything checked out OK. Also the monitor powered up and has been running fine.

Unexplained Blank screen.


Looks like your Power Supply has gone Kaput .. Usually it is the Electrolytic Capacitors on the Power Supply Board, try a new one, or replace ALL the Electros with same or better ones.

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.
