Question about BenQ FP731 17" LCD Monitor

Power light on but no viuals

When switching the monitor on the screen does show its on and the power light is also on but there are no visuals. I see a couple of people on the net with the same problem and I don't think the suggested solutions are helpful. Does it mean the Monitor has a 3 year long life only.

Power Light Blinking & Black Screen


A blinking blue light indiactes that your power-inverter board is not putting out what it should. It needs an overhaul which may be a simple as changing out the capacitors on the boards.
It could go beyong that to transistors or even a bad bulb.
It will have to be opened up to do that.
A picture may show visual signs of damage. If you can take one and email it to me , I'll take a look.

AOC lm720 no screen plus blinking green light


Sorry to say, but it sounds like you power board is due for an overhaul.
It should be fixable since it does show signs of a little life left in it.
It would have to be taken apart. A visual may tell for sure.
Look for bulging capacitors (canister looking things) This a sign of a typical failure.
Of course, not all capacitors bulge when they go bad. That would make things too simple !!
