Unfortunately not. After reballing every ram IC and finally the apu I get a different Error regarding a short somewhere. Need to investigate this. Hopefully I don't have to reball the apu again :-D

Thanks for your suggestion. In the meantime I reballed the South bridge. Now the console is stuck at a pulsing blue light.
I read the error codes from the uart interface:

80000140: APU Freeze (No Response) - GDDR6 Data Line Issue (Replace)

So either RAM or APU. Applying pressure to each IC and APU during boot did not solve the issue. Judging by thermal cam all RAM ICs are heating equally.
So how to find the culprit? Don't have spares at hand. :-/
Think I'll have to reball all of them....

Hi there,
Tried to condense the problem in the title. Hope it was appealing for someone.

I bought a broken PS5 with 2 sek. BLOD. When it arrived I noticed the bad condition of the console housing, bent cooler pipes and deformed disk drive. Yeah , obviously very bad drop damage. And obviously not appropriately described in the offer. Because it was my first hand on a PS5 for an okayish price, I decided to take the risk.
It is an EDM-020 CFI-1116A.

First thing I noticed was wrong initialization amperage. It went to 450 mA an then dropped to around 150 mA. Figured...

Re: Dell XPS 9365 - USB-PD Controller dead - Needs programming? Experience?



Thank you for your detailed answer. And sorry for the late reply - must have missed the notification.
So do I understand it correct, that it may be possible to program the Cypress IC in place? That would be way more comfortable than my idea:
- Prepare arPi as SWD programmer
- solder wire to VCC, GND, Clock and Data pins and connect to rPi
- Try to read bad ICs flash
- write good ICs flash

Let me check for a JTAG interface or such. My answer...

Re: Dell XPS 9365 - USB-PD Controller dead - Needs programming? Experience?

Update:
Partial success. The replacement IC finally arrived and I swapped it. It seems to communicate with the charger and establish a connection. Unfortunately only 5 V. 20 V are needed.
So I need to find a way to program the IC. Any suggestions how to proceed?
I'm thinking about trying to read the defective ICs flash via SWD and write the contents to the new IC. But I have no experience with that. If you have let me know.

Dear all,
currently I have a dead Dell XPS 9365 sitting on my bench. Fault description "Used to charge sometimes. Now not charging at all". Confirmed. USB-C Charger doesn't output anything. So probably no charging protocoll was defined. Further testing by voltage injection revealed the USB-C PD IC (CYPD4125) heating up.

So my question is:
Has anybody experience in replacing above IC? Does it need manual programming? According to the datasheet it contains an ARM CPU and internal flash. According to the laptop schematics it is connected to the EC via I2C....

Re: New Members - please post your introductions here

Hi there,
I'm doing hobbyist electronic repairs on various devices with varying success rate. Recently I stumbled across this forum and was impressed by the massive knowledge present here.

This has helped me a lot. I hope to be of help for someone else in the future.
