Re: BenQ, power is on, screen is almost black, just very...
You can not fix this problem from the panel buttons, the problem is
something to do with the circuit board. Its the inverter cicuit that
has one or couple of components faulty. I susgest you bring it o
the repair shop. cheers.

all modern LCDs have ONE and ONE only native screen size. since you did not tell us the model number we have to tell you maybe you are setting the wrong size. if the monitor has worked before then you are sending it the wrong signal.
Disconnect the signal cable from CPU and power on.You should get a BenQ Blue screen.
If no Display,Problem is definitely monitor related ie monitor has a hardware defect most probably the power/invertor board has a few blown components.
If you are technically able,you can dismantle monitor and check components on the Invertor board which you may find on my other posts.
