Check the caps in the power supply first.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

SOURCE: Monitor wont turn on, green power light on

Hi you can inspect that what's wrong with your monitors. After you turned it on and the screen went black, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

Screen won't turn on


You can try to do the monitor self test.
Monitor Self Test:
1. Physically test the monitor autonomously from the computer.2. Switch both the monitor and the computer off, and then disconnect the VGA cable le from the computer.3. Turn the monitor on, pressing the power button for about three seconds. The self-test screen will come up .4. If the image is clear, bright, and shows red, green, and blue, the monitor is working properly. Video issues may be due to the video resolution in the computer, and not the monitor.5. If the image is not apparent and intense or the colors are not accurate, then the trouble is with the monitor or some of the (OSD) settings. In this case, test your particular monitor's information for OSD.
It is always important to check the color of your power light for so you can distinguish if the monitor is defective. Getting red lights on the the power panel states that the power section of the monitor is faulty.

Our CAL232 TV will not turn on. When pressing the power button, you can see a red light and a green light, but the screen doesn't start up as normal. The TV then tries again after about 20 seconds, but...


Hello,

My LOEWE CAL 232 will not power up. When the power button is pressed, the monitor turns on, with the LOEWE on the monitor, then the TV continues with the previous activity (antenna, DVD, VCR etc.). Now all that happens is

1. the red light comes on

2.after about 1 second the green light turns on for about 12 seconds

3. the the green light turns off for about 1 second

4. then the green light turns on again for about 12 seconds

and this continues until the power button is pressed to turn the TV off. During this time, the monitor does not turn on and the only sound I hear seems to eminate from the power button.

Any thoughts?

I have a 24in wide lcd monitor for my computer and


mcdevito75 here, The red power light usually means the monitor is off, if when you press the red button it turns to green, or blue then the red power button means the monitor was off. Your monitor could be burned out.

My hannspree monitor wont turn on


You should ensure that 1) the monitor is plugged in, 2) it is set to the proper input (VGA, HDMI, etc), and 3) the monitor power light is green instead of orange.

Good Luck,

Power light blinks red, green and off. No picture


Is there another monitor input on the back of you computer? Sometimes this happens when your graphics card is not compatible so it is best to try another one. If you have another one plug it in there first. If you don't try the monitor on a friends computer. If it still does the same thing, it may be a manufacturer defect and may need repair.

Wont turn on, nothing.... Power supply is good


Replace the power-cord.

Wait until midnight, and turn out all the lights in the room, so that's dark in your computer room.

Turn on the monitor, and see if you get any light and/or any lamps (green? yellow? red?)

Try a different monitor attached to your computer.

Try your monitor on a different computer.

Wont post led 3 flashes


if its the red flashing light on the tower, its the hard drive activity light.

when the monitor goes on stand by, does the tower retain power? (green light on and flashing red light sometimes?) Does your keyboard's scroll lock/num lock/caps lock keys and keyboard lights work?

Monitor won't turn off


Monitor will be like that until it is powered off. Only when it is powered off, the light goes off and there will be nothing on display.
