This is not a problem but I want to know what's going on with my LG L91A 19" monitor. I've been using this monitor for the last 3 years and I have no problems with it. Recently I realized something strange:
After I use my computer, I always switch off my multi-outlet electrical socket which provides electricity for my PC, external HDDs and monitor to make sure that there is no electrical flow through the system. While I was staring around the monitor, I realized by chance that the on/off light on the bottom-right corner was flashing every 15-20 seconds. It flashes in a pale blue color. Normally when the monitor is on, it is always on with a strong neon blue color. First I thought that this could be due to the capacitors, but after a few hours the flashing was continuing as I checked it. I observed this situation several times. Another thing I realized yesterday was that a few minutes later as I cut off the electricity, the monitor's screen flashed just for a split second in a semi-bright gray color. I thought that it is some kind of electrical discharging but I'm not sure. Is that normal? What's going on inside my monitor?
My multi-outlet electrical socket is something like this:
