Benq monitor flashes primary colours when switch on or off


This is called burn-in mode. Used to test the monitor at the factory.
To fix this, use the buttons under the front of the monitor,
There are six buttons. Let's number them 1 to 6 from the left.
Press 6 to display menu (at the bottom in Red will say Burn in mode on)
Press 4 or 5 until Recall is highlighted
Press 6 to select
Press 4 or 5 until Recall All is highlighted
Press 6 to select
Press 4 or 5 until Yes is highlighted
Press 6 to select
Press 3 to exit
This will reset all paramaters and also turn-off burn-in mode
If you want to reset some parameters to your preferences, press 6 again to bring up menu and
see you user guide to get explanations for the different settings.

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.

Benq monitor powers off immediately


Try sending monitor back as most Benq monitors come with at least a two years silver warranty. Benq are very helpful and their repairers are quick and polite. You will find their no.s on their website www.benq.com my monitor was experiencing the same and for $10 postage and a one week wait is repaired and working fine.

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.
