Give the video below a watch, it's 1h long but pay attention to the console symptoms (sometimes works but with no Wi-Fi, sometimes blue light, sometimes 3 beeps) and pay attention to what he says about the 8mA current draw around 30 mins into the video and again the 10mA current draw (after replacing the damaged part) like you are seeing due to the 32kHz oscillator not running what he ultimately finds out the issue is (southbridge!).

Not 100% identical to your issues but there are obvious similarities…I also prefer this guy to any other YouTuber that does console repair, he is very methodical in his approach, thinks about what he is doing and rarely fails to fix the issue. He also does PSU repairs on camera which is interesting to see as well seeing as most people run away from PSU faults and just replace the whole PSU as they are afraid to work on them.

Cleaned up some solder joints and now it jumps to 59ma and back to 26ma. I have a southbridge on order. Pretty sure we are on the right track. Time will tell. Thank you.

Yeah ToltecMerc's vids are great. I will review this one. Thanks!

Update: New BIOS chip programmed with known good BIOS BIN. Same issue. 0.01 current draw. I have purchased a PSN banned board off of ebay. Going to compare voltages , verify. This may be the APU or Southbridge. Not sure. More investigaing needed.

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

They should get warm, check the datasheet for output voltages.

Oh sorry i missed that. 40 celsius to 85 celsius. Well the highest i have seen is 60 celsius on the chip to the left of the APU. The one below the RAM chip is running low 40's to 50.

3219a - tps53219a

Lotas,
I am wondering if they are worth replacing. Dont want to go down another rabbit hole. What you think?

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

There are (2) 3219A chips on the board that appear to be heating up. The first is located left of the APU and the other is located just below the bottom left RAM chip. If i had a known good board i could see if these chips getting warm normal or not. Anyone else have a EDM-020 board? Maybe we can work together to fix two units?

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

So while I wait for the new bios chip to arrive. I decided I would take the thermal cam out one more time. Here is a look at the EDM-020 powered up. More to come. Need to document part numbers heating up in pics.

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

Roger that. I will keep you posted.

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

i have no idea, never even had a ps5 on my bench.
i'm just interested in documenting/decoding the syscon content for future uses.

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

Stj,
I will check the BIN I backed up later today for that entry. Have you personally been able to find any diagrams of board voltages. I may make one for the board i have. Cod3r has some great vids showing the voltage power rails. But i would love to open up a pdf and be able to reference on the fly. I may buy a psn suspended known good working board and take the rail readings from there. Just curious. Thank you.

001c:7270-7281 may be drivekey.

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

Update: I erased and flashed the original bios chip with original BIN. No change. Still waiting for new bios chips to arrive. Anyone have a diagram they have obtained or created that maps out all the known good board voltages for EDM-020?

[TheWizard]

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

Well i ordered 10 Winbond 25Q16JV chips from Digikey. Plan is to flash backed up bin to new chip, re-solder and pray. Haha But i will keep digging at these entries and where to find them. Will try to find a common placement. Thanks stj!

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

the only way to find it is to compare several dumps and identify the other stuff so only the drive key remains.

unfortunatly when people do post dumps you dont know the serial/mac's etc to look for them in it.

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

Yeah the cypher key is the hard one to find. I remember with the PS4 there was a extractor app that would pull that specific info and make a small BIN to edit with a hex editor.

[stj]

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

in theory there should be:
model,
serial,
ethernet mac,
wifi mac
and maybe the cypher-key for pairing the optical drive.
