Missing 1.8v standby voltage and 3.3v enable


Thats are the standby voltages
Is the 1.8 only Power or Standby also?

In this spot the 1.8V are there if power on. The 3.3V on the lower leg/pin is the enable, if switched on the 1.8V will be generated.

I give Up in this one.
But on a other Board i have Shorts under WiFi IC
But Not in the 1.8v rail coming from f7002.
I think Its the 3.3v rail but i dont know where IT comes from

thats 020 or 010 board you have?

Forget to mention Its a 020

what cap you have short under the wifi module?

3.3v standby gens from stepdown ic on the left side of Southbridge, next to the 2x rear USB-A power switch

Im Not at Home rn but this area with the Little cap IS shorted and the other 3.3v also. The 1.8v are fine.

So the ps5 is working again
Desolderd the First one and the short is gone


New one is a 10uf 6.3v 0402
Big thanks for your Help

i have a edm-020 I get no beep or power I am not getting 3v no where on the board that i can find if you could help be much appreciated

What resistance to ground or diode reading on 3.3v standby?

You should have 1.8v from F7002 area and the other side near southbridge having 3.3v standby. check those area and report back

I sure will thanks… for replaying back

i get 5v and nothing eles

I’m good upto the Richtek where I have no voltage on either 5V or 2.5V, could you support :pray:

I have removed the chip and now, 5V is present. I’m assuming just swap the chip and see how it goes

getting 3.3V line at pin 3 of the six legged limiter chip is the enable line direct from the southbridge
