Normal behaviour near F7002?

[rp39]

Hello,

I'm working on a EDM-033 board. In a previous thread, I asked about AW-XM501 replacement. I should receive J20H100 tomorrow.

I've made some measurements near F7002. Could you confirm that these standby voltages are OK (without WiFi/BT board)?

Seems that 4 caps are shorted (circled). I measure 200 ohms on these which could also be a resistor value. These 4 caps are all connected to +1.75V from back side.

Is this a normal behaviour when WiFi/BT board is missing? I get 80810001 and 80C00136 errors with UART commands.

Thanks

yes, 200 Ohm is correct there on this revision of the board, and you should be getting 1.8V on the output (so 1.75V is fine if your meter is not very precise). The other power rail under the WiFi module (all other caps), you should be getting 3.3V on them, if you do - then everything is fine and ready for new module install

Yes indeed, I'm getting 3.25V on all other caps. As you explain in my other thread, both 1.8V and 3.3V are powering WiFi/BT module.

So everything seems OK and I hope that installing the new module will resolve the issue.

Once more, thanks testerfan

Hello,

WiFI/BT module replaced.

Now PS5 boots, shows screen were repair starts but then shutdowns after few seconds. Here's UART errors :

C0020303 APU access error SB-TSI I2C thermal sensor
80000001 Failed to access the thermal sensor

Will investigate...

Seems that all standby voltages are OK except on SBV IC in back side. 5V is entering but no output (1.9 V ?).

I also have a strange behaviour with current draining : 580 mA then 260 mA after 30 sec, which should be 320 mA then 10 mA.

Something seems to be shorted somewhere.

Hi,

Do you know what the value of those caps are on IMG_20250311_190348.jpg?
I knocked them off and (I know they are going to be all the same value) after taking one off I got a reading of 8.65-9uF. Can anyone confirm if this is correct. Do I need a 10uF 0402 10V (its the only Voltage for 10uf I could find, though I know its all one a 3.3v line)? Would my findings work?

The caps are 0402 10µF 6.3V (or higher 10V...)

Hi bro, just wondering whether your issue is soloved? I met same issue that the PS5 is booting for a few seconds then off
