I have an ASUS VS-228 that's quite a few years old now. When I turned on my computer today I noticed the monitor's LED indicator wasn't on, usually it's orange when it's off and blue when it's turned on. I tried swapping the power cable from my 2nd monitor (which is working still) but even that could not get it to turn on. Is there any other type of troubleshooting I can do or did it really just die?
