The original wifi modul is also a J20H100 and the replacements are J20H100 from a PS5?

Yes the wifi modules are all J20H100's

Took some new thermal images. Providing 12v @1a. I am drawing 51ma. During this stage the Wifi IC heats up along with the (Dialog) power regulator and One Flash memory chip for Nand. After this sequence the amps drop to 21ma and components cool down. See pics.. Anyone have any ideas?

Anyone have any other ideas? I did notice that on my known good working EDM-020 Disc edition board. It has an AW-XM501 wifi module not the original J20H100 module. I heard they are both compatible. But maybe that is my issue?

Update: Flir thermal cam was misleading me a bit by making me think there was a cap or nearby inductor heating up first. Not liking how the Flir shifts the thermal layout. Went old school on this ps5 last night and broke out a can of freeze spray. First component to get hot was the NXP chip followed by inductor and nearby cap. Looks like I will need another wifi module. Trying to source the AW-XM501 this time

https://www.richtek.com/m/Products/...Phase Step-Down Controller/RT8237F?sc_lang=en This is the first component right directly behind the F7002 circuit inductor on same side of board. There is a short on that inductor both pads. Even with no inductor there the pads are still short. If i remove the wifi chip short goes away. Something is feeding them pads.

Not sure I hate it when they dont always use the same chip. Like they are trying to hide something. Or just make it harder for us independent techs to find and fix. Haha

I guess this is the area you said.
I just got this EDM020 came in these 2days having short on 1.8v as well, F7002 blow too. Let me guess it would be a cap short or what else :rofl2:

Yes sir that is what i have been pulling my hair out about. Maybe we can bounce readings back and forth and cross examine to tag team this issue. :) haha

Jkyoho,
Did you get any further with your board?

Hi !

Got the same issue on a EDM20 ps5, 1.8v short on F7002, fuse was blowed and a cap was shorted dead on F7003. I replace it change the fuse and the wifi chip, the A2 chip etc... but the same.
Do you find how to resolve it ?

Salut. En espérant que quelqu'un puisse vous aider.
J'ai une PS5 EDM-020. Aucun signe de vie, aucun bip. 12v au tableau. Testé environ et j'ai 5v et F7002 c'est bon.
Je n'ai pas de 3,3 V.
J'ai testé les bouchons à 7002 et ils montrent un court-circuit à la terre.
Je les ai retirés ainsi que le circuit intégré à 8 broches, toujours court et les capuchons hors circuit.
J'ai retourné la carte et testé le côté apu.
Le F7003 est bon mais il manque de bouchons. Suppression des capuchons, de la puce carrée et du composant juste en dessous des capuchons. Encore court.
Vous ne savez pas où aller ensuite. Je ne trouve aucun short autour du pont sud, mais les casquettes sous l'APU montrent un short, ce qui est inquiétant.
J'ai vérifié les fuites de métal liquide, tout va bien.
Toute aide appréciée.View attachment 357478View attachment 357479

Salut, j'ai eu le même problème. Pour ma part j'ai dû retirer la puce qui gère le HDMI et le wifi pour éliminer le court-circuit.

    Is it piracy if it was released for free? Not in my opinion, but I also think it's not piracy if buying it isn't owning it, and it's not piracy if you can't buy it from the original creators anymore.
