Aiwa CDC-MP32 Headunit Unresponsive

They are all mechanical, the PS button is the only one that doesn’t click as the rest do but that may just be me

There wasn’t any resistance between the two but I decided to take the inductor out to test it, sure enough tester said it was not working, is there something I can substitute it with to see if that was the issue?
 
A piece of wire, a 1 ohm resistor... It's not critical and if it makes a difference, the diagram has errors. This is only for the RCA shields.

There are some scratches on the ribbon cables, do any of them go deep enough to cut through the copper?

There also appears to be some bare copper. Do you see those areas or is it just an artifact in the photo?
 
The leg of L402 is snapped, should I do the same for that or wait for a replacement? (Its a 10uh inductor right?)

These are the only areas of anything like that (these connect to the board)
