Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you aregood at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts, replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to trythe repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

Hi, My g. door opener doesn't work. The


5 Blinks on the logic board LED indicates that possibly the motor has overheated. If you have unplugged the unit and waited minimum of 30minutes before plugging it back in, and it still will not operate, then the logic board will need to be replaced.

My monitor screen is black and the yellow standby light is blinking. I can not get the light to stop blinking or get the monitor to show anything, but a black screen. What can I do to coerrect the problem?


mcdevito75 here, Press the SHIFT key, a screen should come up telling you too click on your user name, left lower side of screen. If this doesn"t work, press the yellow blinking light on the monitor see if picture comes back, then follow the directions. If this doesn"t work, shut computer down with switch on the computer itself. Hope this helps.

Change the screen resolution. The video card or video display may not be compatible to the supported video setting of the monitor. Try changing the video resolution to a lower setting such as 1024x768 and bit depth to 32 bit.

Monitor goes black but the green light stays on. I turn the power button off and then back on and it comes back on. It may stay on for a few seconds to several minutes.


Check to see if the image is Dimmed. Chances are the power supply on the FPD is either dead or not supplying power to the back lights.

Your problem is the back lights are not being powered. There is a signal going to your FPD because the power light remains on green, but the back lights are what helps support an image from the Front Panel Display.
The only way to fix this is to open it up.

If its got 3 boards inside((logic-->video, Inverter, Power)) The problem is the Inverter. Replace it.
The inverter is the board that supplies power for the backlights to turn on. The backlights
provide a light.for the LCD Panel(provides color and is the logic. ... similar to a projector.
If its got 2 boards inside ((Logic-->video, Power)) The problem is the power supply. The inverter is embedded onto it.

Simply replace the part with a known good one, and you got a spanking new monitor.
