Very easy to install and easy to operateā€¦just double click the icon.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 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 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 splitterthis 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.

Laptop Screen Goes Black - You Won't Believe The Problem

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.This was happening while using the laptop at random. Before this happens.

I will however post some of those links anyway for you to review, it is always possible there may be something in one of them that may have been missed or may inspire an idea of the cause. Since you mentioned that sometimes just moving the screen will cause the problem or make it disappear, that does seem like either a loose connection or maybe something like pressure on a part of the display causing the issue.

Of course that last part may just mean the display is on its last legs, but hopefully not. First I will give you a link to the service manual, to help you check the connections. Just be careful to read the sections on precautions, to protect yourself and to prevent any other damage.
