I Have a Few Issues, In Desc.

First off, After unplugging hdmi from tv, It won’t get a picture when plugged in, I assume its because the settings got defaulted, and the tv isn’t detecting resolution?

But Here comes my other problem, The system REFUSES to turn off. It’s ONLY off when its unplugged. When I plug it in, It turns on by itself. And the Power Button has no effect, but clicks. Because of this, I can’t Power Cycle? Is that the word?

Any ideas on the issue? Im fairly familiar with taking systems apart, so thats no issue at all. I Just don’t wanna take the system apart without understanding the possible problems/solutions.

thanks for the responses and the time to read!
