I have an Slim 360 which I'm using in China, powered through a high-quality 220-110 convertor. The 360 starts to power up with green light ring flashing momentarily, then shuts off. power supply light goes red. Resetting the power supply light is orange then goes red when I turn on the box. Is this a power supply or box problem. I want to get a new ps when back in US in a week if it's power supply.
This might be the Red Light of Death for the Slim. Basically meaning the CGpu chip needs to be reflowed or reballed.
But there are some other possibilities:
Chinese electrical power might run at a different Hertz than that of North America. So your Power brick could be partially damaged with a short.
Or an IC or Mosfet might be out on the motherboard.
Now that I re-read your post .... Leaning towards that you have a damaged brick
