Hi guys. I want to ask about the PS1 SCPH7000. I accidently desoldered and lost the SMD on the motherboard which is shown in the red circle in the attached photo.
Is there any way to fix this?
Thanks.

It's a 4x22R 0402 SMD resistor network - but it looks like some of the pads are missing too. Try soldering some small 22R resistors in using the test pads (you only need to install 2, becuase only 2 are being used).

Thanks for the reply.
I don't quite understand the solution. Do you mean i buy four 22R 0402 SMD resistor and solder all 4 parallel to each other just like the original SMD resistor network? I don't know which 2 of the 4 to install.
I found them in this website. https://my.element14.com/search?st=22r 0402
do you mind telling me which one to purchase by their manufacturer part number?
thank you.

OK, by the look of it you can't solder a replacement SMD part in because the pads it would solder to have been torn off the board. This is the part you would need if you could (all 4 resistors in one package):


If the pads are intact, just solder that in.

If they aren't (which is what appears to be the case from the photograph) then you need to solder in two individual wire ended 22R resistors - put one between the pads marked "A" and the other between the pads marked "B". Use a small resistor like this:
