There could be something else causing the issue, and here are a few of the other things which may be causing the problem. It could also be the result of overheated parts in your laptop or computer too, but unfortunately this is difficult to diagnose. An overheating monitor can be a result of a few things, with the main cause being a lack of ventilation to the components inside.
So, make sure that you give the monitor a thorough clean before you start it up again. If you give it a few hours to cool down and then restart your computer, it should work as normal.
Another possible problem is an issue with your video card drivers. If you think that this might be an issue on your device, then the best thing for you to do is update them. Here is a good guide on how you can easily update your graphics drivers.
You can do this by going into your device manager and finding it pretty easily. Although it is pretty unlikely, it could just be that your GPU has run its course and is dying on you. Read below thoroughly to solve this issue:. Well, the graphics drivers are the principal parts associating and passing instructions from your Windows operating system to the graphics hardware.
On the off chance that these are corrupted or outdated, you will encounter faltering and peculiar issues like the screen going black for a few seconds. Now right click on the display adapter and click on the Uninstall device option. Note: You do not have to install the graphics driver again, it will be automatically installed if you have Windows If you have an older Windows version like 8 or 7 then you will need the graphics card driver to install it again.
If the problem still persists go on with the next method. On the off chance that Windows is responsive, a short signal will sound, and the windows screen will dim or blink while your Windows system endeavors to wake o refresh the screen. Well, some third-party software programs can be the reason behind black screens. To ensure that you video card driver is not at fault, download the latest video card driver from the manufacturer's website.
You can determine which video card you have by opening up the Device Manager and reviewing the model name and number of the Display Adapter. To do so: click Start and type in "device manager"; then click the Device Manager link when it appears.
The Device Manager window should appear; look for "Display adapter" and click it. Your video card name and model number should be listed there. Use the monitor as you would normally after updating the driver to see if that fixes the problem.
If it still doesn't work, proceed to the next step. If you have tried all of the above steps, you have eliminated the majority of issues that can cause a monitor to go blank. At this point you will want to determine if the computer or video card is causing issues with your monitor. To test this theory, reattach the monitor to another computer to see if it works properly. In that case you will need to try another video card to see if that resolves the problem.
If you've made it this far in the process of elimination, then most likely the problem is with the monitor itself. In that case I suggest you try another second LCD monitor to see if that fixes your issue.
If you have no issues with the second monitor then the first monitor is most likely bad. To verify that theory we once again use process of elimination.
To do so, try the first monitor on another PC and see if you have issues on that system as well. If no issues then your first monitor is most likely somehow incompatible with your original first PC. For example: a few years ago I had a monitor that kept turning off sporadically. Over time, the problem got worse, to the point where the monitor kept turning off and staying off with nothing but a black screen. I verified this by using the monitor on another computer only to get the exact same result.
I managed to fix the LCD monitor by soldering new capacitors onto the power supply of the monitor located inside the monitor.
You can watch a video on Youtube on how to replace capacitors on an LCD monitor if you are technically inclined. For most folks, however, taking apart a monitor and soldering on new capacitors simply won't be possible.
Keep in mind if you purchase an older, used monitor, you may encounter the same problem down the road. If you do purchase a new monitor, I suggest spending a little extra and get one with a good brand name. Based on my experience, Samsung makes excellent monitors ; they use premium parts including premium capacitors , which should guarantee a long life ahead.
I still have one Samsung LCD monitor from and it's still going strong. My suggestion is that you re-read the article from start to finish and try all the steps I just mentioned using process of elimination. Start with the cable: make sure it's tight and hooked in properly to both the PC and monitor. If it still doesn't work, then replace the cable using another brand and repeat.
If that still doesn't work then try another monitor. Eventually you'll figure out it's either the cable, video card, monitor, or possibly the computer that is the problem. I kindly ask at this point please do not email me "What do I do next? On the other hand if you have a separate computer question you'd like to ask me, then follow through to the next paragraph.
I need more computer questions. If you have a computer question -- or even a computer problem that needs fixing -- please email me with your question so that I can write more articles like this one.

Sometimes the monitor will not show any display right from the start, sometimes it may work for months and then suddenly start with black screens.
Most of the time it is a random issue and owners fix it by repeated shutdowns and restarts till the screen shows. This is caused by the display driver stopping and starting - particularly with AMD cards on Windows Try reinstalling the display drivers - for AMD you need to make sure all the old drivers have been removed - then do a new install.
I have this problem too, and I know it's not a cable or monitor problem, since I have two fairly new monitors connected to the computer. This started happening shortly after upgrading to Windows I have upgraded both my video card and memory, which I thought would fix it. I have a brand new monitor and was having this problem. I borrowed a "larger" HDMI cable and that seems to have solved my problem.
