Hi!
Maybe it’s software fault you never know but try to go to boot menu and try to do something there. I don’t know much about that PS error but you should maybe watch YouTube video or something.
Kind regards
Just going to give this a little bump. Still searching for a solution. Could it be APU related?
The PSU works fine in another Slim. I’ve cleaned the console top to bottom, new paste, it has all its thermal pads, connections are all good. Fan comes on fine, hard drive is fine.
I was able to get it started but it shut down before I completed the setup.
