Hi guys!

So I had a one beep not light PS5 Slim EDM-040 console with a HDMI port bad and after reading standby voltages I had 1.2V, 3.3V, 5V, 12V then I checked the power supply and it didn’t get me the 0.300-0.200 mAmps when I was trying to turn it on so I decided to take the southbridge off.

As you can see in the photo is a Cxd90069gg, I started with hot air at 200*C worming up the surroundings, then I was gradually adding more heat every 2 to 4 minutes till I stop at 400*C and adding more flux from 300*C. When I saw the bubbles around the chip I knew that I was closer to extracting the chip, I didn’t pull it straight away I just push gentle in a corner of the chip and when I saw that it moved I lift it up with my tweezers.

Now, the problem is that after I lifted the chip I realized there was a pad that got stuck in the BGA chip leaving the board without that pad, I could trace and repair the pad but I don’t know if it is necessary, I got the schematics of a EDM-010 and I know that they may have a different southbridge (I’m assuming). So I came here to ask for some assistance or schematic for the Cxd90069gg chip.

Thanks in advance! And I’m sorry if left something behind you can ask me anything, I’ll be glad to answer

Note: in the schematics that I found of the EDM-010 it says that this is a NC (not connected) pad, so I don’t know if I am lucky enough to leave it as it is right now.
