I received a call from one of my clients who mentioned to me that their monitors just went out. Upon arrival, I checked the physical connections and they seemed to be connected properly, but I still see the following issue - see attachment. The monitor in question is a Sony sdm-hs94p. I rebooted the pc and still nothing and the strange thing is that when I attempt to hit the SCROLL LOCK key on the keyboard, no lights turn on/off. The same thing occurs when I hit the CAPS lock key as well, no lights turn on / off.
Any ideas on how to troubleshoot? or fix?
