How to fix my Benq Monitor which is scrolling full screens of different colours.


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.

My LCD is completely dark - I can 'just' see the desktop, but can't do anything. If I turn the LCD monitor off and then on, I get maybe 2 seconds of the desktop - not long enough to do anything.


This sounds like the CFL tubes are not working properly, this is common.
If under warranty then return it, if not then get a technition to replace tubes.
Or it might be cheaper to buy a new 20" LCD screen.

Please do make sure though that the brightness is set to it's maximum by using the menu buttons on the screen itself. It would be some-thing like menu then right arrow to brightness then select button, right button again to increase the brightness.

Please rate, it's the thumbs up.
Thanks

Power light on no screen shown


unplug from pc, turn on monitor. if there is a 'no signal' or any image displayed on the screen then the problem is not the monitor..

Screen is dark


your backlight is out and one of two things can cause this . 1 being the invert board is failing, or you have a couple of bad caps in the power supply. you can see the bad one they look like little cans , the bad one will have puffy tops on them ...if you see them change them or have it done if not them you will need the inverter board serviced or replaced

It sounds like a LCD backlight problem. Bring it to an authorized repair shop.

BenQ, power is on, screen is almost black, just very dark


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.
