Hello, I'm telling you about the attempted repair of this PS5 that arrives without turning on, 3 seconds and turns off.
Check all voltages, there are no shorts. Using uart method gives me the error
80830000 Low Shutdown or Freeze After SAM_IPL Loaded - GDDR6 Data Line Issue (Replace)
I check with a thermal camera and all the rams heat up, I check the resistors, everything is fine.
I do a slight reflow to all the ram (num 2) without touching them, and one of them gets a ball, so I decide to reball it.. Curious, after this I do uart, and now the error is:
8080110C Severe RAM GDDR6 (Bank 3.4) - Single Beep, 1 second blue light, off.
So I decide to change ram 1-4, one by one.
When I have changed the number 3 and 4, using uart it appears:
808016F0 High Not found in list. Report Findings.
I already have numbers 1-4 changed, so I start changing numbers 8-5, one at a time.
I change the number 8, do uart and error:
80801630 High Not found in list. Report Findings.
Change number 7, I do uart and error:
80801690 High Not found in list. Report Findings.
Change number 6, I do uart and error:
808016B0 High Not found in list. Report Findings.
Change number 5, I make uart and error:
80801630 High Not found in list. Report Findings
I think the rams were defective since looking with a thermal camera they heated up first half and then the other half of each module, something abnormal.
Well, once all the modules have been changed, with a thermal chamber they heat uniformly and normally, ... I use uart and error:
80830000 Low Shutdown or Freeze After SAM_IPL Loaded - GDDR6 Data Line Issue (Replace)
Again,…jjjj
So I decide to go for Apu,... I do reballing... and the result is as expected, damaged APU,... 1s blue light, and uart error:
80810001 Low General Power Failure (Periphery, GDDR6, APU, Data Line Short)
And measuring, there is short vcore,... game over.
In this case, the ram and the apu were bad... there are already several PS5s with dead apu... bad for Sony!
