This came in for No Audio. While testing it, I noticed it restarted on me as well. So anytime we have a random restart, we gotta check the panic log.
I noticed the panic log (see pic 1) mentioned Apple CS42L75 Audio
So then I searched the schematics on JCID Drawing & found the Audio Codec is CS42L75.
So the panic log is saying, this chip is related to the issue.
Now the thing is, I haven't fixed it yet.
But I at least know where to start. Check the main Audio IC. And go from there.
Otherwise, I wouldn't know where to start. Audio IC? Speaker amp North? Speaker Amp South? I've even had Arc Driver in the past cause audio problems.
And if you don't know, the Arc Driver is the same chip as Speaker Amp. Although I'm sure it's for the taptic engine.
So, have you seen this panic log before? If so, what did you do to solve it?
Here's a quick video i did on this:
If you have a Seek Thermal Cam, you're missing out if you don't have a VCC Seek Stand: https://www.vccboardrepairs.com/buy-seek-stand
Injured Gadgets just got these back in stock, so get them while you can!
It can take us a while to build these out sometimes, so they're sometimes out of stock for a while, but we're working towards always having inventory ready to build more as they sell out.
This stand makes using a thermal cam so easy. So much better than any other thermal solution on the market.
It allows you to get real close up (using my Macro Lens), and easily find where the short is coming from.
Plus it's hard free, so you can have your hands free to try to boot the device from DCPS, while having an image that is in focus & not moving around.
You can even record a video through the app, while you inject voltage into the short, so you can go back & see exactly which component was it that was heating up.
Save yourself lots of time by getting a Seek Cam, Stand & Macro Lens! ...
Anyone who is doing game console repairs, knows how many screws you need to remove to access the motherboard.
Especially the PS5, with the 5,000 screws or so.
