Hi guys. Total noob here to the PS5 board repair scene. I have an EDM-033 board that gives the one beep no light error. My knowledge is very limited concerning the process of diagnosis and possible repair of the system. I have used UART and below are the errors:

I checked F7001, it was blown. I replaced it, cleared the error logs, tried to boot the system…that was unsuccessful. Checked UART again…same errors. I also did some probing and both 5V and 12V are present, did not locate any 3.3V. Any guidance on how to proceed, greatly appreciated.

F7002 area has dc2dc ic gens 5v to 3.3v

Hey, Thanks so much. I checked these areas. They all have the proper voltages. Where next can I check for errors given the UART log.

4

Did you check the left and right sides of the f7001 for shorts before replacing it?

5

What do I check for and how do I check for it?……. Remember….. totally new to this scene.

6

How were you able to add a picture to your post? Every time I try it says “There was an error, you cannot add a picture” or something to that effect.

I replaced it because it was shorted, There was no continuity beep when I assessed it.
