Why does my computer monitor randomly turn off?.


My monitor keeps going black. Sometimes I have to power it on and off 20 times before the monitor will work properly, and some days, my monitor won’t turn on at all! When this happens, my monitor power light stays yellow as if the monitor is sleeping or in standby mode. Normally the power light is green when it is powered on and working properly.

Any ideas why my monitor keeps turning off? There are many reasons why a monitor keeps turning off, resulting in a blank display. The best way to resolve this problem is through process of elimination; as such, I will go through the list of things you can do to help determine why the monitor keeps going black or turning off sporadically.

The first thing to do is to ensure that the monitor power cord and the monitor display cable are securely connected. To get started, turn the monitor around to reveal its backside, taking note of the the cables running to it.

The monitor power cord goes from the power outlet to the monitor. If it is not secure, the monitor simply won’t turn on indicating no power led in the front of the monitor , or it may cause the monitor to short out. In this case, ensure that the power cord is pushed in all the way and the connection is secure. Next, check the monitor display cable. The monitor display cable is the cable that delivers the picture from the computer to the LCD display.

It runs from the back of the computer to the monitor, so you will need to check connections at both ends this time. Follow the cable all the way to the computer and note where it is plugged in. Now, ensure that the cable is screwed into both ends. Note that HDMI cables cannot be screwed in.

Otherwise, I wouldn’t be able to plug the cable in. Now, power the monitor on to see if it comes on. If not, try jostling the wires on the power and video cables to see if it causes the monitor to turn on or go blank. If one of the wires is at fault, then the display will turn on and off to coincide with your movement.

If no change, proceed to the next step. Simply put: both DVI and HDMI are digital signals; if the signal is too weak, the monitor won’t sync to the computer, resulting in a blank screen.

If the cable run is too long, or of the signal has been split using a non-powered DVI or HDMI splitter , this can cause the monitor to go black because the signal isn’t strong enough. Based on my experience, some HDMI cables will simply stop syncing properly after a while, even though they worked fine previously, and even though the same cable works fine on another device.

Sometimes, HDMI cables won’t work properly if there has been a recent hardware configuration change. For example, you may have purchased a stereo receiver and ran the cable through the receiver instead of directly through the monitor. In this case, you can bypass the splitter or receiver and see if that makes any difference.

At any rate, I suggest you try another HDMI cable if you have one lying around to see if that resolves your problem. If not, purchase one that has a high AWG thickness as this will help to ensure a strong signal. Assuming that the cables are plugged in securely, power on the monitor and check to see if the monitor keeps going black.

If not, proceed to the next step. If a monitor power cord or display cable are pinched or twisted especially at the very ends , this can cause the signal to become short circuited, and the screen to go blank. In this case, you will need to unplug both the power and the display cable to the monitor as well as the one to the computer and physically examine them.

Sometimes cables can be pinched if the computer desk is lying on top of them usually because the desk has been moved or shifted. More often than not, however, the cable ends become bent or twisted usually due to a tight fit in the back of the computer or monitor, which results in the cable shorting out. If you noticed any pinch marks or tears, or if the ends are badly twisted or bent, then you should try replacing the cable. If you have any bent pins, you can try straightening the pins using a screw driver – but ensure that the power to the monitor is unplugged beforehand.

If you have Energy Saving Mode or a Screen Saver enabled on your computer, this can cause the monitor to go black or power off completely. Now, use the monitor to see if it powers off or goes blank. If it still doesn’t work properly, proceed to the next step. The video card driver determines how the computer negotiates power saving mode with the monitor, among other things. 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. Question is: I don’t need a 6 ft cable and would like to buy a shorter 3 ft? Why do you recommend a longer cable? Will a 3 ft work? Thanks for the solution. Glad I found you!

The post was great! The thing it’s as other guys: I have two new monitors and everything tested.


How do you fix a computer screen that keeps turning off –


So, you have just started your day by having a healthy breakfast and turning your computer ON. A few minutes have passed while working on the computer. Okay, this may not bother you.

While some of them are associated with the monitor, a few relate to the computer system. Following are these causes:. When a monitor is overheating, it automatically goes OFF to keep circuitry damage at bay.

The reasons for overheating are excessive heat, dust accumulation, or vent blockage. If the monitor is old, too much dust accumulation jams the monitor vents due to which the heat cannot escape. This can result in turn OFF to keep the risk of disrupting the circuitry. Another cause in the case of an old monitor is the set of aging capacitors within the monitor circuits that are unable to retain the charge for sufficient time for supplying it to the other parts.

If overheating is the cause, disconnect the monitor and allow it to cool completely prior to connecting it again for use. Before how do you fix a computer screen that keeps turning off put it back to use, do clean the vents using a vacuum cleaner gently. Alternatively, you can use anti-static canned air to blow away the dust inside the casing of how do you fix a computer screen that keeps turning off monitor. If the room in which the computer is present is hot, cool it down via an AC or a fan.

Allow the room to cool prior to using the monitor again. If aging capacitors are the cause, consider reducing the brightness of your monitor. По ссылке so consumes less power due to which you can then use the monitor.

In the case of a very old CRT model, consider replacing it with a flat-panel display to fix several heat-based issues at once.

At times, carelessness or a silly thing can be the cause of this monitor issue. So, just examine the cable that connects the monitor to the system and see whether it is loose or not.

The same problem can be with the power cable or cord that connects the monitor with the socket. At times, the monitor cables could be damaged via twists and pinches whose symptoms are visible at the ends. This can short-circuit the signal and make the screen go black. As a wise user, the first thing to do is to unplug both the monitor display cable and the monitor power cord and re-plug them securely and tightly. For this, just see both the ends of /10864.txt cable at the rear of the monitor.

The power cord runs from the electrical outlet to the monitor. Once found, remove it and reconnect it. The display cable responsible for rendering the visuals from how do you fix a computer screen that keeps turning off PC to the screen runs from the rear of the monitor to the rear of the CPU. Ensure that you screw the ends well. An HDMI cable cannot be screwed but you how do you fix a computer screen that keeps turning off tightly fix it.

In case of small space or too thick cord such that it cannot bend well for connection, consider investing in an HDMI adapter. Now, watch the monitor to see if the issue is resolved. If you are using these cables, you need to take care of some additional considerations.

Both of them are digital signals. So, адрес страницы any of them is weak or has been split using a splitter, the monitor is likely to go blank due to loss of signal strength.

This can happen even if жмите сюда cord is too long. At times, an HDMI cable tends to stop functioning well due to a recent hardware setting. For instance, you may have used the cable for an external device such as a splitter instead of plugging it directly into the monitor. If this is the cause, you can test just by removing that external how do you fix a computer screen that keeps turning off.

At last, try checking with another spare HDMI cable. If this does not fix the issue, consider buying a new but thicker HDMI cable to get a strong signal. In case of a damaged cable, unplug it and physically check it for bent pins, tears, twist marks, and pinch marks. To uproot this cause, you will have to replace the cable. If there are bent pins, you can first try straightening them with a screwdriver after disconnecting the cable.

You can easily check if this is the cause in your case. If resolved, it means that the GPU was at the how do you fix a computer screen that keeps turning off. This cause is common in case of an external GPU card, which could be dead or faulty.

Here, for verification, consider using the graphics port integrated into your motherboard. These days, most CPUs or motherboards come with built-in graphics.

If it worked, it means that the external GPU card is faulty or its driver is obsolete or not updated. You first should update all the graphic card drivers. You can download and install the latest drivers from the official website of its manufacturer.

To know the manufacturer and update these drivers without going to the official website, perform the following steps:. If the issue is still there, consider cleaning the card and put it again on the motherboard. If doing also does not resolve the issue, the only solution then is to replace the graphic card with a new one. Sometimes, dust on the PSU and its fans can cause the issue. Clean the PSU and its fans. If the issue is still there, test with another powerful PSU, which only a technician can do safely for you.

It is not recommended to do this on your own. So, you need to buy a new PSU. It can even power it OFF completely. To negate this cause, perform the following steps to reset the power options and stop the screen saver:. It is easy to fix the issue of the monitor turning OFF and ON repeatedly by trying one or more solutions mentioned above.
