Benq Monitor Won’t Turn On

How To Solve The ‘Benq Monitor Won’t Turn On’ Issue 

As we have already pointed out the reasons why your BenQ monitor isn’t turning on, now we can look into them one by one and go for the solution.

1.Replace the Faulty Monitor Power Cable

In most cases, an old and weary power cable is the culprit. After a period of usage, the cable gets damaged and your monitor won’t turn on. 

Try a different cable to power up your BenQ monitor. If it works, then throw out the old one. But if the problem persists, then you have to check the power outlet.

2. Faulty Power Outlet

Sometimes the wall socket or power outlet on the wall is faulty. The pins can get damaged, chipped, or even fried. Hence your monitor isn’t getting any power.

Use an electrical tester to check if there is an electrical flow on the outlet. If not, you might need to change the socket. Remember to turn off the main power breaker before you do any electrical work in your home or office.

3. Replace the Graphics Card/Video Card

A bad graphics card can set your monitor with a black and unresponsive screen. As there is no output from the card, your monitor won’t get any signal to turn on.

If you have a monitor handy, use that to check with the graphics card. When it won’t turn on either, you can be sure that it is the graphics card’s fault. At this point, you have to take your computer to the computer technician to have a look at it. You might need to change the graphics card or need to update it.

4. Update Graphics Card Driver

Another thing with the graphics card is that when the driver is outdated, your monitor won’t turn on. Although it might turn on with a little effort, the screen will glitch and jump around. 

Update the graphics card drivers. You can do this simply by visiting your graphics card manufacturer’s website. And download and install the latest driver. Then restart your system and your monitor will work just fine as usual.

5. Take the Monitor to Technician

Like any other electrical equipment, the monitor is combined with a lot of electrical circuits, boards, and capacitors. And with any electrical surge or overload, they fall victim to damages.

If this is the case, and you have a warranty, you should contact your manufacturer. They can fix it for you or even replace it. Do not attempt to open it and do a DIY on it. Even if you don’t have a warranty, take it to the technician, and they will fix it.
