Question about Computer Monitors

Monitor intermittently goes dark and will not come on

Having problems for about a week, monitor may jump or flash, once a white type light up the middle of the screen, then goes black. If i turn the pc off, unplug everything and wait 45 minutes or so, it may come back on. is the monitor going out? I've had about 3 years - do I need to update a driver or something? I have checked all the ''power source'' /connection problems and that's all ok.

    I have the same problem, do you hear a whine? Anyway my guess is the backlight is dying.

Monitor Goes black, or flickers on and off


The high pitch sound is coming from the inverter. It is faulty and needs to be repaired or replaced. The inverter supplies high voltage to the CCFL lamp, this lamp gives the backlight to the LCD so you can see the LCD images.

Monitor goes Black off and on .....


I had the same problem for about a week and solved it yesterday by downloading the latest driver by NVDIA who makes my video card (NVDIA GeForce 6200).
I had previously updated the latest Sony driver for the monitor. It did not solve the problem but could be part of the solution in conjunction with the new video card driver.

Monitor Black, Green Power Light Flashes Monitor is 4 yrs. old


Assuming you've already checked your driver and system settings, tried a different monitor, and checked the cable and connector pins, this would almost certainly be a problem with the power or signal circuit board inside the monitor.
