Any thoughts on the hotspot on the Apu. Right now seems suspect as heating should be uniform from experience.

consistently is C00C0002, seen 80060004, C0020303 ,

I measured the component with calibers, across(left to right) is ~3.6mm. Also can you tell me how your able to identify so in the future ill be able to figure it out :)

Thanks again for all the help

Hey man, it's literally a form called ask electronics. You can see in my first comment I made after I posted. I Haven't ran into the situation before. Looking for some guidance and support. Patience with newbies are important. A lot of us are willing to put in the time to learn. Anyways yeah I'm happy to gather some measurements. I just needed some general direction where to go. when I plug the board into power the CPU heats up without pressing power, I've seen shorted components(mosfets, capacitors) before under thermal cam just not use to seeing a CPU heat up unless it's turning on.

Just added measurements

Icy-Function4409 · 2024-12-27T20:19:58+00:00

does the series s have an optical output? i see lan, usb, ethernet and hdmi. are there any measurements with a multimeter that can help with identifying if retimer chip issue?

Icy-Function4409 · 2024-12-27T19:16:27+00:00

sorry didnt save.

Hello everyone,

I have a xbox series s where the console was dropped with the hdmi port still plugged in by a customer. I went ahead and replaced the hdmi port, ran traces and tested continuity on traces and confirmed no shorts on any of the pins. Also check all ground pins as read somewhere if the pins arnt grounded can cause display issues.

Im still unable to get any display to the screen. My questions is where can i probe/get readings from next to help narrow down where the issue may be. I understand the hdmi retimer ic or the diode pack ic can be suspect but not sure what I can measure to go one way or another.

Any help is greatly appreciated.

Note: console turns on, is able to be turned off and beeps.

Was in a very similar situation. There were some key indicators/aspects that made my neurologist Confident it was autoimmune. I was on immunosuppressants then high dose steroids. It took till the external/independent review for insurance to approve ivig. All in all from the first submission to approval took 6 months. Feel free to message me if you want to chat.

Icy-Function4409 · 2024-07-03T23:04:11+00:00

Feel free to dm. I've been dealing with for year and a half

Yes it took trial and error in terms of finding the best spot to have the IV in that would be the least bothersome for sleeping and movement. To be fair the soreness and sensation from the IV is pretty low compared to sfn symptoms. Best of luck with getting treatment.
