PS5 EDM 020 TPM Issue

[FiXiNGA]

Hi,

I have a PS5 on my workbench with 2Sec Blod. All voltages look good, RAM and APU are getting warm for 1sek and then shutdown. I read out the errlog as you and only had those two problems:

80800014 TPM 2.0 chip / Power failure
808F0002 TPM 2.0 chip / Power failure
I swapped it with a donor and then got

8080001A

So it seems that TPM is married which makes sense cause the reason of this chip is encryption. But now I have no idea to fix this.

Best regards!
Andi

No sadly not yet.

You cannot use another TPM, the problem is rather with power going to YOUR TPM.

Good luck!

Okay. I measured around and got 3,3V as well through the PullUp voltage for the Enable line. So I cannot understand what is wrong. The Southbridge ist getting a signal from that TPM. Maybe there is an issue.
