Try a different known working monitor and hook it up to the computer. Turn on the computer and the monitor and see if you can get video. If you get video then you know the original monitor is bad.

If with the known good working monitor you still don't get video then you know its something either with the video card or the motherboard if you have integrated video.

Where can I find instructions on replacing the backlight on benq fp731?


jsiwiec, Are you absolutly certain that the "cold-cathode-fluorescent-lamps" need replacing, or if the "switch-mode-power-supply"/"CCFL inverter supply" is not working and is in shutdown mode? CCFL's are not some kind of miniature version of those energy efficient screw-in new style, curlie-Q cfl light bulbs you buy at the local home-center!!! In any case here are some places to checkout first. www.ccfldirect.com ,
www.teliostech.com , www.ccl-la.com/badcaps.htm , www.lcdparts.net, www.lcdrepair.us You do know that most times the problem is not the lamps. Did your LCD display have bright, crisp, colorful images displayed on the lcd panel 2- 3 days before black screen happened? How many TOTAL "ON" hours of use on this BenQ FP731 ? When was unit produced? Good luck with repair. Hope info was helpful.

My aoc lcd monitor appear full white screen


Most probably failure in the LCD controller IC in the lcd controller board. that no signal was sent out to the lcd driver ic thus you could only see white display on the screen. A replacement of LCD panel might be the solution. regards

Blackout on plug in!


Try your monitor on another computer or another monitor on your PC. This will tell you if the monitor has a problem or your video card (or connection).

Can't find video signal


If screen says "Signal cable not connected " all the time till power led switches to Amber chances are monitor is ok and problem is with graphic card or cpu.Connect to Known working CPU and confirm that monitor is the problem.
If same problem persists on another working cpu after changing signal cable,the interface board in the monitor could be defective.
