LCD Monitor screen keeps going blank

displayhardware-failurelcd

I have an LG LCD monitor (Flatron L192WS). I've been using it since 5 years, never had a problem but from yesterday onwards suddenly after 20-10 minutes of working, the LCD screen goes blank.
When the screen is blank, the power LED on the monitor is still ON and the power and HDD LEDs of the CPU are also on. When I turn the monitor's power off and turn it back on, the screen appears and it could be seen that all the processing of the system works fine then it once again works for 15-20 minutes, sometimes even longer and again the screen goes blank.

Can anyone help me understand what could be the problem?

Also, could it be some sort of virus/malware or is it purely a hardware fault?

This could be an issue with your Power Saving Settings. If you open the Control Panel and go into the Advanced Power Settings via Power Options there will be an option called PCI Express. Expand that option and check the value of Link State Power Management. If that is set to anything other than Off, that could be causing the monitor screen to go blank.

I had a similar issue to yours a while back and this is how I managed to resolve mine. This may not work for you, but it's worth a try. If this is not the issue, it could be any number of other things.

I would first try and check if the problem persists with another cable. It may just be that the cable you're using is not making proper contact with the monitor/gpu and any slight movement is causing the screen to go blank.

If a new cable doesn't help you could try another connection on your GPU. The problem is most likely hardware related, but you could try a virus/malware scan to rule out that as a possible cause.
