Computer monitor suddenly turn off. What happen?

December 14, 2007 4:57pm CST
Does someone know why a computer monitor suddenly turn off? Everything is okay (cable connections, etc). The only problem is that there is no green light on the right corner of the monitor when the button is pressed. You know... when you want to turn on your monitor, you'll press a button which then it will have a green light -- Now, there is no green light. The CPU is running well -- no problem. I have already checked it. What happen with the monitor? How should I do?

This was just based on my experienced, I'll just want to share it to you. Option # 1: (IF YOU ARE USING A VIDEO CARD & IF YOU HAVE AN ONBOARD VIDEO CARD) Try to unplug the cable attached from monitor to Video card, then transfer or plug the cable from monitor to the ONBOARD VIDEO CARD. If still doesn't work the Video card or the onboard vidro card was'nt the problem. Option #2: Try to replace or use different cable attached from your monitor to the Power supply of your CPU, If still doesn't work, The cable was not the problem. Option #3: Try u replace or use different Power supply from your CPU because it was the sources of POWER that goes to the monitor. If still doesn't work, the power supply was not the problem. Option #4: Try to use different AVR, if still doesn't work, AVR wasn't the problem. Option #5: Try to Plug or connect your monitor using all the original cables to other or different CPU, If still doesn't work, the CPU was not the problem. Conclusion of my own based on my own experienced: I therefore concluded that there was no a problem with the CPU or other parts of the computer , and the problem was the Monitor itself or the MONITOR was malfunctioned which is need to be repair. I hope it helps.....

is your monitor power coming from the CPU or is it attached directly to an outlet? if its the former, then its possible that your PSU (power supply unit) could no longer allocate enough power for both monitor and CPU needs. in this case, the solution is often simply plug your monitor directly to a power outlet if its the latter and you are using a CRT monitor, its possible that one capacitor (or tube) blew up and needs to be replaced. how long have you had the monitor? CRT monitors have a lifespan of around 5years only (as compared to over up to 15years for LCD monitors).

Thanks, qradav. My monitor power is attached directly to an outlet.

are you using CRT or LCD monitor? if its LCD, its least likely that the problem is associated with the monitor itself in which case, I would recommend you check your video card. if you are using an onboard video, then try to uninstall it, restart your pc and install the driver again. see if it helps

When I first open the power it lightup green but after 1 sec it turn to orange, anyway I already replace it with new one, cuz i test my friends monitor to my pc and it worked well. So i knew what the problem is, thats why i bought a new one. My old monitor is already 5 years old its time to replace it.

But I am not a technician. Thus, I am rather phobia to change the cable inside the monitor.

I think your graphics card has some problem because when graphics card become loose then it happen, so open your PC cover and check the graphics card. Some if your RAM become loose it happen, so open your cover, open RAM and clean its connection place then again set it. You can check with other PC if your monitor is O.K. or not.

Thanks. Your advice is similar to the previous poster. I'll check the CPU.

Maybe it just simply burned out, perhaps from leaving it on too long or from pressing on/off too often and too quickly. If not, then check your cables, see if everything is plugged in tightly and correctly. If everyhting seems to be right, then try getting a new monitor and see if it works.

Maybe check the power settings options in control panel to see if it's not set to turn the monitor off (or similar). Also try connect another monitor, or mains cable if possible, to see if they work; If they do, there may be a problem with your monitor or cable.

I can't see a control panel because the screen is blank.

Try another monitor with the computer, if it works then your monitor may be busted. how long have you had it? if its recently bought then use warrenty to have it replaced/repaired. if its kind of old you may have to purchase a new one... nothing lasts forever.

I was also facing the same problem. The possibility is that the capacitors from the monitor may have damaged or have been short. I suggest get your monitor checked from a technical person to get the problem solved.Such problems occur if your monitor is old. This is a monitor problem and not the CPU problem. If your monitor is in waranty period then get it repaired in waranty soon.
