I have a Mag Innovision monitor that has the external AC adapter mentioned in the title which has gone bad. Is there any way to repair this or should I just purchase a replacement?

Did you try heating it up with hair dryer to see if it will put out any DC after warm up? Especially the small startup cap (22~47uf 50v) in the primary side. You will not see any bad sign on the small cap.Never stop learning

Good point Rtech, it may also have ZENER Diode (15~16V) across the output to act as crowbar protectionNever stop learning
