Disconnect and power the backlight using a separate supply; apply a dummy load to the inverter. That is how it is done in the shop.

There is no fault in repairing them both together since both derate quickly and fail if you have brightness on full. Hack the Planet and other blogs have some hints if you want to replace the backlight with something stronger...solar (lightpipe) power, etc.

There could be some issue in PC as well as in the Monitor also, to check Monitor, please follow the below steps-
1. Disconnect the VGA cable from the computer.
2. Please check if there is any kind of display on monitor.
3. Please check what is the color of Montior LED, if it is still yellow and if there is no message on Monitor then there could be some issue in the monitor. For this, you need to get in touch with the Monitor manufacturer and get it repaired otherwise please get in touch with the computer manufacturer to get computer fixed.

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.

BenQ FP591 15" monitor decides to die


Strange that both should show the same symptoms don't you think? Have you changed anything computer wise? Graphics card or resolution? Screeching noise is a puzzle too. How are they powered - internally or via a separate power supply?
