PSOne Slim, not getting power at all.

I’ve checked the fuses, all appear ok, caps appear ok, I’ve used a multimeter to check everything I can think of, and using an original ps1 slim power brick, still getting no green light, even tried jumping some fuses as it worked for another guy, nothings working? Anyone have any ideas on how to get this console running.

Thank you!

Attached photo of the motherboard so easier to identify anything I might have missed. Also multimetered the dc socket, power is going through around 7.5v, continuity passed on all fuses, no other chips appear damaged.
