A PS5 I'm working on is having a weird issue I haven't seen before. When you power it on it'll run for anywhere from a minute to 10 minutes perfectly, no video issues or anything. The it will blank out with a long beep only heard thru whatever tv it's plugged into, then immediately power off.
Power it back on it'll do a quick repair for not powering off properly then boot back up. Then it will run again for a minute to ten minutes then the same thing...
I've done a tear down and no obvious signs of anything burned out. Any suggestions on what could be going on? Anything to point me in a direction of a chip to replace or anything would be great.
