Hi, my BenQ FP72G 17 inch LCD Monitor keeps auto-adjusting every 5 seconds and every now and then it will turn itself off and later go on again. Any help ?


Make sure the cables are in well with a good amount of slack, it can cause a problem if your power cable or computer to monitor cable is loose

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.

BenQ FP72G 17" LCD Monitor NO DISPLAY


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.

BenQ FP72G 17" LCD Monitor NO DISPLAY but when i shine a torch on the screen, it shows the display. Does anyone know exactly which compoent i need to replace on the Inverter board ? All transistors seems...


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.

Benq 17"Lcd monitor fault


Resolder the power transistors on inverter board and also check them.If display is not there at all some of this 4 transistors C5707 should be defective.Check associated fuse and Fet which drives the transistor.

Also check with Benq ,Normally offers three year warranty.

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.
