1 Answer

Monitor light blinks

I have tried 4 monitors, 4 video cards,3 motherboards, and a lot of combinations of all. I hook my monitor up to the power and turn it on. the light comes on and no connection floats on the screen. Hook it up to the video card turn the monitor on steady light then a click and blinking light and nothing on the screen. If i plug in the monitor turn it on i get a steady light a no signal floating on the screen. But if I plug it into a video card just a video card no computer no MB just the video card I get a click a blinking light and nothing on the screen.This started a few months ago and I can't figure it out yet. Back then it started with me rebooting to scan my computer and it started and has not ended yet..The monitors work on my stepfathers computer. Just read the first of my letter again I have tried and tested power supplies cords Ram pentium 3s & 4s HDs floppys Disk drives

    How do you test the power supply connection? Forgive me for sounding like a moron, but where's the connectors? There's three coming from my monitor...

Have you tested the power supply connection feeds? test each connector I think you will find your power supply has failed on either the 5 volt or the 12 volt side more than likely 5 volts are down' the agp adapter needs 5 volts to run. since you have changed out every thing else I would replace that or test your dads power supply in your computer, that should do the trick

Samsung syncmaster 2220 blinking blue light and no image display


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Good luck.

After boting monitior is getting shut down


When the monitor shuts down, is the activity light on the monitor blinking yellow? or staying yellow constant? Have you tested another monitor? When does the monitor shutdown exactly what is the computer doing at the time the monitor shuts down?

1. Blinking yellow means failing monitor. Not all monitors will exhibit this behavior. For example my Acer Monitor blinks with a blue light when no video input is detected. It doesn't always mean the monitor is bad, but may indicate the video card is failing. Also check and/or replace the video cables

2. Solid yellow means no video input detected Not all monitors will exhibit this behavior. For example my Acer Monitor blinks with a blue light when no video input is detected. It doesn't always mean the monitor is bad, but may indicate the video card is failing. Also check and/or replace the video cables

3. Testing another monitor tells you if the video card is failing. If another monitor works, the problem is your old monitor failing, if a new monitor doesn't work, then the problem is more than likely a failing video card.

4. It is rare but sometimes the Video PCI slots can go bad, while another may work on the same motherboard. This further indicates if it's a motherboard issue, and not the monitor or the video card. Just change the PCI slots the video card is plugged in to and see if it works.

5. Power issues can cause this video issue as well; For example if your PSU is not strong enough to support your video card, it may exhibit no input detected issues past a certain point in the boot process. This is due to lack of power being supplied to the video card. MOST video cards have a warning of sorts if this is a case, but some do not. This issue is more common with higher end gaming video cards and/or lower end power supplies.

The best way to test this is to disconnect ALL devices from the motherboard that require power; For example; CD drives, Hard drives, USB devices that may be plugged in other than keyboards/mice. Only boot the PC with the video card, RAM, and CPU installed. If you get video start attaching 1 device at a time and doing a fresh boot with each device connected. So if the PC boots fine with video on the monitor when the CD Drive is plugged in... it's not the CD Drive causing it. Then hook up the hard drive WITH the CD drive, and see if the PC boots with video then... If it does not, you can infer a power issue might be causing the problem.

Another issue that may effect the video card directly pertaining to power issues are; Try swapping the power cables to the video card with a different power cable. That is to say a power cable coming from the Power Supply that isn't connected to anything or in use by anything else. It is possible a power cable line is bad and/or not working in which case it's a Power Supply issue.

In some cases; This test will be negative on all accounts; At this point, It may be your RAM/CPU causing the issue; Try reseating the ram, that is to say uninstall the ram physically, use a cloth to clean the gold prongs on the ram sticks, and place the ram sticks back into the motherboard; See if it boots up with video then. If it does not; Try removing ram sticks 1 or 2 at a time as required and checking again. This helps determine if it's a specific ram stick causing the problem.

6. If the video STILL is not showing up you will want to check the following.

Check the motherboard for blown capacitors; They will appear in the following forms; Clearly bubbled tops on the capacitors; Exploded tops or yellow crystalized liquid leaking from one or more of the capacitors (like battery acid). This causes a HUGE list of random issues that are symptomatic of power issues. In this case a (Failing Motherboard) Most common on intel and dell motherboards especially on older hardware/PC's.

The CPU is the hardest thing to detect if it's failing, and is rarely the cause, if common sense and care are taken when handling a CPU.

At this point if you still can't figure out what's causing the problem; Replacing the motherboard or monitor is recommended. Monitor if you do not have another monitor to test. Or motherboard if you've exhausted all other troubleshooting steps.

I realize it's a lengthy description, but your description of the problem wasn't exactly specific so I wanted to be thorough and cover all the basis that could cause this problem.

Hope this helps.

The power light on my PC monitor keeps blinking and the monitor wont come on


There are a number of reasons why this is happening, but one thing for sure is that your data are safe.1. Try to check your PC monitor. Check the power supply and try to connect it to another PC if it turns on. 2. PC could be under sleep mode. Try tapping the keyboard (Enter, Space Bar), move the mouse to return it to normal operational state.
3. If your PC came with another video card, try connecting the PC monitor to the on-board video card connection.4. Check your PC if the fans are running, if its not, it could mean that the power supply is busted.

How's the status light of your computer monitor? is it blinking amber? and the status light of your computer tower's power button? blinking amber as well or solid green or no light at all?

1. Disconnect all the connection at the back of your computer tower
2. Press the power button of the computer tower for 15 seconds
3. Reconnect the power button and the monitor cable at the back of your computer tower and turn on the computer (if it turned on that means that one of the device plugged at the back of your computer tower is faulty)
4. If still the same problem, open up your computer tower.
5. Reseat the video card, Reseat Hard drive, Reseat Memory, Reseat CPU, Reseat power cord coming from the CPU to your computer (doing all things one-by-one to pin-point the root cause of the issue)

If none of the troubleshooting steps fixed the problem, possible that the power supply is faulty and if the power supply is faulty sometimes it goes with the motherboard.

Monitor not on but menu light are blinking


Hi there, i assume you switch on the monitor but there's no display. Is the monitor working before this? If what i assume is right, you should check the connection between the monitor and the cpu. If that doesn't solve the problem, then you should check the vga card. Maybe the pci slot/vga port is damage. If that the problem, you should change another display card.
