Acer S200HL LCD Monitor Troubleshooting

The Acer S200HL LCD Monitor displays a 1600x900 resolution picture across its 20-inch screen. Troubleshooting this device may seem difficult, but this guide will help.

Black screen ¶ 

Your screen is not turning on when you're pressing the power button.

No power ¶ 

If your monitor is not receiving power, the power cables of the monitor may have become loose and power isn't reaching your monitor. Make sure that the monitor is securely connected to a working power source and that the cables are not frayed or pulled free from their connections.

Low brightness setting ¶ 

Sometimes the display of the screen is set on low to conserve power or has been accidentally manually set. Power conservation mode can be a reoccurring problem if your computer is set to go into energy saving mode. Try to access the display settings by your keyboard command buttons. There is usually a power/battery icon button in the lower right corner of your screen. If you click the icon it will direct you to your power manager from which you can change your power settings.

Corrupt new software ¶ 

If you have recently had a software update and your screen went dark shortly after this update, then you might have corrupt software. Sometimes corrupt software can be easily fixed by rebooting your system; restarting might trigger a better compatibility between the monitor and the software. If rebooting does not fix the problem, use the system restore function found by searching 'system restore' in the windows home search, to restore your computer system to a point before the update. Alternately, try re-installing the software that is causing the problems.

Lines on screen ¶ 

Your screen has horizontal or vertical lines on the display when turned on.

Bad cables ¶ 

If lines appear on your screen, you may have loose or faulty cables. Check the DVI or VGA cables connecting your monitor to your computer. Ensure the cables are securely connected to the correct input. If the problem persists, try using a new set of DVI or VGA cables.

Old drivers ¶ 

If you are experiencing screen glitches a common source of this problem is outdated drivers. Check that you have the most current hardware drivers for your monitor and video card.

Bad power supply ¶ 

If lines appear on the screen, many times a bad power supply is the cause of this problem. Check to see if the power cables are securely connected to the monitor. To check for updated drivers, go to the device manager in windows and find the malfunctioning device in the list. Right-click on the device name and go to the properties window, which will display if the drivers are up to date or not. Also, make sure the power cables are connected to a working power outlet.

Bad internal cables ¶ 

If there is a distorted picture, a common cause is a loose cable inside the monitor. This requires disassembly of the monitor in order to repair the problem. Check that the various internal cables are securely fastened. To see the steps to check the cables, click here.

If lines appear on the screen there is a possibility that the display screen is damaged or faulty. In this scenario, the display screen may need to be replaced with a new screen.

Sticky buttons ¶ 

The buttons on the monitor are sticky or not responsive.

Residue under buttons ¶ 

There might be unwanted residue underneath the buttons. A common solution for eliminating residue is by taking a can of compressed air and spraying around the button. If the problem persists you might have to open up the monitor and repair it.

Monitor turning on and off ¶ 

The picture on the monitor is turning on and off for short periods.

The screen is switching between a standby and an active mode ¶ 

When set to maximum resolution and brightness, the screen may switch off to protect itself or to save power. This problem can be solved by restoring the screen to more efficient resolution and brightness settings. To change the brightness, use the brightness button on the lower right-hand side of the monitor. The brightness button will open up a menu allowing you to manage your brightness settings. Alternatively, the menu button, located next to the brightness button, will make a pop-up menu appear on the screen. If given the choice, click on the “Auto” or “Auto-Adjust” option.

The capacitors are faulty ¶ 

If the monitor has issues turning on and off the capacitors, which give power to the monitor, may not be working properly. This results in the screen flickering on and off.

The ribbon cables are not firmly attached ¶ 

If the ribbon cables are not securely connected, the picture on the screen will sporadically turn on and off. For a repair guide on replacing or reconnecting ribbon cables, click here.
