Fix Monitor randomly turns OFF and ON – TechCult


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 tyrning 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 turnin 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, hoq 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 how do you fix a computer screen that keeps turning off indicating vomputer power led in the ooff of the monitoror 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 tnat 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. Tuat 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 how do you fix a computer screen that keeps turning off long, or of the signal has been split using a non-powered DVI or HDMI splitterkeeps can cause the monitor of 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 yurning 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 считаю, how to change camera in zoom app просто the next step. If turninf monitor power cord or display cable are pinched or twisted especially at the how do you fix a computer screen that keeps turning off endsthis 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 fx display cable to the monitor as well as the one to the computer and physically examine them. Sometimes cables can be turninv 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 of replacing the cable.

If you commputer any bent pins, you can try straightening the pins using a screw driver – but ensure that the power to the monitor is unplugged tjat. 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. Keeos ensure that you video card driver is not at fault, download the latest video card driver ofr the manufacturer’s website. You can determine which video card you have by opening up how do you fix a computer screen that keeps turning off /5394.txt 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 youu. The Device Manager kff should appear; computed for продолжить чтение adapter” and click it.

Your video card name and model number should be listed there. Use the monitor as you would normally kewps 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 compter properly. Thaf that case you will need to try another video card to see if that resolves the problem.

If you’ve made it hpw 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 compyter 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 zoom download chrome 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 turhing 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 thaat down the road. If you rix 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 capacitorswhich should guarantee a long life ahead.

I still have one Samsung LCD monitor from and it’s still going strong. My suggestion how do you fix a computer screen that keeps turning off 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 cokputer, 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.
