I have a Dell ST2310 monitor that I used for about a year. When moving the monitor to another PC, when the power cord is attached the screen flashes on/off/on/off continuously. I can briefly see the Dell logo on a black screen during the flashing. I tried using two additional power cords and hooking it up to a 3rd pc but have the same results. The monitor worked fine when I used it last (about 2 months ago. What is causing the flashing and how do I fix it?
Any insight would be much appreciated.
Sounds like your capacitors are failing. You could have it repaired, but it may be more cost effective to buy a new monitor.
Sorry for the bad news,
