2 Monoblock Class Ds Not Working, I'm Lost

I have a random assortment from various electronic part-outs

There are 2 parts , power supply and amplifier.
If the power supply died it can be fixed easily
If the amp died, almost all silicon in a class d gets fried when it fails. Outputs shorted and driver chips shorted , the oscillator comparator may still work.
If it died bridged both channels may be dead.
 
Power supply seems to have had a previous repair as there were some char marks on the heat sync and board around PS fets, not to mention 4 different batches and a shorted fet. I replaced all PS fets with new and same-batch fets. The amp powers on normally but seems to have an issue with the protection circuit. I believe the output fets are fine but I'm unsure about the driver chips as of right now, and I'm not sure how to check the oscillator comparator.

To Perry's message I will double check the caps are discharged and will update when I have soldered them.
 
Are these alright for the capacitor ratings? Both are 50v rated

Also these are the connections to the board, aren’t pretty but they make good contact to the board and to ground (checked with multimeter) Looks alright or should I be aware of anything? Just want a second opinion

Wires are to connect to the capacitors as the cap legs are too short to reach

Sawtooth on LA5
LA 3 and 4 showed oscillation

Saw this near output, could this be a cap that leaked or glue, etc?

This (photo) is on LA5 and speaker output, seems to be about 5v with gain turned all the way down, amplitude changes with gain by a little

Yes there is square wave on both high and low side

It was with driving signal into it

Half protect light is back

Gain changes amplitude still

Changing the subsonic messes with the wave a LOT and the amp makes a lot of weird chirpy sounds when changing it

None of the other pots did anything

Changing the switch to slave cleaned up the wave and wave gets blurry in master mode
