Normally this is caused by the power inverter for the lcd.It is a small circuit board1521 laptop screen comes on for approx. 2 secs - 2.gif right below the lcd, that powers thebacklight. If you take off the front bezel of the laptop you should beable to see it, it will have a 2 wire power cord coming out the oneend, and another plug in on the other end with several wires.

9 times out of 10 the problem is just the inverter going out, check ebay for a replacment but make sure you get an identical model as the one you have, as they are very specific to each laptop. The inverter will have the part number written on it.

Black screen issue


If all lights are coming on, hook a monitor to the video output, if okay the inverterboard just below the laptop screen is defective or the built in backlight behind the LCD display. But! if both show the same symptom it is the video graphics chip.

My dell inspiron 1521 screen goes black!


Yes, most likely the inverter has failed if you can still make out the desktop but the screen is very dim. Below is the link to the service and repair manual for that model.

LCD Screen problem


You have a failed inverter circuit. This is a very common fault with BenQ and other LCD monitors. I have seen more FP737 and FP731's and all their cousins in the last 2 years then I care to count.

You will be best to take it to a TV technician and have them do the repair. There are ways to fix it yourself, but the chances of success are not great without a decent amount of electronic knowledge.

Call several places and get approx quotes based on the inverter fault. A lot of TV techs will not work on LCD monitors and is another good reason to call around first.

One final thing, check the manufacture date on the back of the monitor, these normally come with a 3 year warranty and it will be either expired now, or very close to it. If it is still under warranty, then contact BenQ near you to facilitate the repairs.
