Question about Samsung SyncMaster 551 15" CRT Monitor

1 Answer

Screen suddenly goes blank

The monitor goes blank after a few minutes,, and the LED power indicator of my monitor blinks faster than normal. I tried to turn off the monitor then turn it on again, the screen was back to normal but after a few seconds it blacks out again. It happens again and again. I don't think it is caused by the video card. I have been using this monitor and video card for a few years already, and this is the first time this happens. The signal cable is okay (I checked it). Is my monitor broken? thanks

    Thank you for replying to my post. Sad to say, it still happens. LED light when i press the numlock key still blnks on and off, so the video card couldn't be the problem.When i open the computer, yes i still hear the click sounds. Maybe the monitor really is broken. Thanks a lot.

When you open your pc now,do you still hear a click sounds like you hear before ,when your computer has no problem yet? now there is no sounds .do the ff..
1.try to press the numlock key and observe it ,if the indicator LED lite on and off,the problem of your computer is your video card,
2.if you can't hear anything, when you open your unit and the indicator of your monitor goes the color orange,pls..check your memory .clean the memory and the memory slots using the contact cleaner .before you replace a new memory.
3. and try to use a another monitor,maybe your monitor has the problem.

Why does screen go black after a few seconds


Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand).

Was watching a movie on my computer last night and all the sudden the screen started turning off and on with no picture when it was on. Has the monitor gone bad or is it a video card issue?


The simple way to check if this is a Monitor issue or not, you can unplug the monitor from the Computer and connect it only to the power outlet. If it gives you a "No signal" screen or goes through any sort of other Self test, Your monitor is fine. You can also check if the power led is blinking Amber or Green. A blinking Amber LED while the monitor is only connected to the Wall outlet indicates the monitor is faulty.

Asus Monitor boes blank and comes back after power recycle


1. You can see images on the screen for a few minutes. That means there is nothing wrong with your computer.

2. When your screen goes blank, if you disconnect and then reconnect the monitor, it shows fine again for a few minutes before going blank (or dim) again. That means the problem is not with you video card.

3. It always shows the image after reconnection for exactly a few minutes before going blank again. yes? this means that there is nothing wrong with your cable.

Conclusion: Sorry, but you do not have many options. I bleieve that the problem is with your monitor that's going bad. Its far cheaper to get it replaced than to repair it.

Monitor goes blank after 5-10 minutes


You may have a compatibility issue with your monitor. You computer may not be putting out enough power to support your monitor. Check your users manual on your monitor for output requirements. If the monitor's manual has a number to call, call the manufacturer to see if there are any compatibility problems between your computer and your monitor and calling the people who built your computer as well. Get as many scenarios as you can to find a solution. Hoped this helped.

Computer Won't Power Up


If the blinking amber LED is on the computer itself and not the monitor, this is most likely a power supply issue. First thing to try would be replace the power supply. If the blinking led is on the monitor, it probably has bad capacitors and needs to be replaced. (or repaired)
