Question about BenQ FP731 17" LCD Monitor
Hi, I have an lcd screen which is palying up. When you switch it on it satrts up and the normal no signal notice appears for approx 1 second. If I then plug in the RGB into my laptop the laptop desk top appear on the screen for approx 1 second then disappears. The same thing with a desktop. Whenever I plug in a RGB the screen gets the siognal for approx 1 second then the screen goes black again. (please note: If I leave the LCD switched on and keep pulling RGB in and out of laptop everytime cable is attached the screen comes on for approx 1 sec the black again)
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.
