Monitor No Picture

Hi! when ever i boot up my pc the monitor also boot up and running fine but sometimes did not boot the monitor, than the screen color turn orange and freeze, and at times it totally do not show any picture only blank screen. Later i tried to switch off the PC and wait until the indicator light went off and reboot the PC again, and it work fine. At times i have to try many attempt before it is working. I have defag, clean, run antivirus, spyware, Adware. PC spec: XP, SP2, can anyone help and what is the cause for this to happen. thanks Mike

Sorry to hear about your video problem. It is bound to be one of three things. The monitor, the video cable or your video card. The behavior you discribe seems to be about the monitor not being able to handle or process the video signal it is recieving. Things to checkout: 1. Is my video output on my computer on a separate video card or is it part of (integrated) with the motherboard. Or is there both? If both try switching to the other connector (on board vs video card) **Advanced ** You might have to go to the bios and enable/disable a integrated peripheral. Or change a order of use. Pci-agp, or agp-pci or pci-pcie if this is not a auto detect function. 2. Watch the LED powerlight on the montitor as you boot up. Does it go Green? (means monitor is getting a signal) Or is it going amber (means monitor not getting a signal) 3. At what point does this behavior occur? After post and a splash screen? (could be a video driver thing) A good thing to know. 4. Do I have another monitor in which I can see if the problem follows the computer? (would tell you right away where the problem is) 5. It the cable from your computer to the monitor built in to the back of the monitor or is it a removable one? either way check for bent pins or not seated all of the way in to the connectors. If removable can you get a replacement to test with? Personal note ….when I first started working on computers I didnt have much money for additional devices, so I was plugging and unplugging the cable from my only monitor into lots of machines and ended up stressing the cord to the point of having one of the wires in the cable break. So I would have to wiggle the cable to get all of the right colors displaying from then on. 6. Depending on you confidence and skill, open up the case and check for dust, dirt debris in the components. Remove the video card if a separate card, inpect, clean and reseat. The easiest way to troubleshoot this would be be replacing things with known good items. Intermittant problems are a real bear, they wont happen when you want them to, and do when you dont. Regards and Good luck. Kazzoo

it is a direct connetion to the monitor.
when monitor not responding thr LCD is amber.
usually when i boot up.
i don't have another monitor to check ( no money to buy another one )

is it due to the inside of the PC dirty and what is the best way to clean it.

thanks & regards

It can be one of the reasons you get the fail that you do. You got a big clue because the monitor is reporting (going into standby) that I am getting ac power, I am connected to something but I am not aware of any video signal. If you can not get a different monitor to your computer, can you move your computer to a different monitor? Dusting out is just one of the possible steps after checking out the other troubleshooting options I mentioned. But with that said, most computers can use a good blow out once or twice a year. You can go to most any computer shop or even Walmart and purchase a can of compressed air. It is in the computer/electronic section. (usually around 5 bucks a can) Take your computer somewhere where it isnt going to matter if you blow dust around. open up the side and give it the dust out. One caution mind you is not to turn the can up side down and use it. You end up blowing the propellant all over the computer and it is moist and cold. Not one of the things you want to do to circuit boards. If you do end up doing it, Give it a few minutes to dry out before applying power. Regards and Good Luck Kazzoo
