This is most probably cause by one or more Faulty Electrolytic Capacitors, I find these are the MOST commonest form of "Fault" in these LCD's TFT's units. I ususally simply replace "On Spec" all High Value Electros, in fact ALL Electro's are suspect and often I just "Shotgun" and replace 'em all. Usually fixes all problems. Always use High Temperature Caps.

My knowledge of using the command line is equal to my knowledge about astrophysics. Zero. You can change BIOS settings in the BIOS Setup utility. After the computer manufacturer's splash screen, (Logo screen), and at the bottom of the screen, are shown the key/s to press to enter BIOS Setup. Goes by real F-A-S-T. Try to write it down. Let Windows load all the way, then restart the computer. As SOON as you see the manufacturer's splash screen, start tapping on the key/s to enter BIOS Setup. If you miss this window of opportunity, let Windows load all the way. Turn the computer off normally. (Wait at least 20 seconds) This time as Soon as you press the Power On button, start tapping on the appropriate key/s. (In 2 second intervals) You don't get as far as the splash screen? Then unplug the computer from power. Observe Anti-Static Precautions. Remove the CMOS battery, (CR2032), for 1 minute. Press the Power On button in, and hold it in. Hold it in for a count of 5 seconds. Let go of the Power On button. Do this procedure two more times. Install the CMOS battery. Plug into power. WAIT 1 minute, turn the computer on. This procedure will set the BIOS Settings back to the factory default settings, and clear CMOS Error Codes. Post back as to your findings.
The message is being created by the monitor not Windows. The only thing you can do is look for the option to disable it on the monitor's menu options. NEC-brand monitors will have something call "Onscreen Notification" which you can disable. Hopefully your BenQ will have a similar option.
The silver hwite/grey screen means that the LCD panel is not getting the signals, 5vdc from the logic board. Try reseating the connections between the logic board and the LCD panel first.
Also check the power supply caps.
Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you. Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series
I am looking for the LCD panel from a 567 V2.
If you can't repair the problem e-mail me and I would like to buy one from you for parts. [email protected]
