Electronics help needed on botched keyboard repair

Hiya
I snapped some toggle switches off my yamaha synth front panel. I tried to repair it myself and got some replacement switches and opened it up to do the soldering on the panel pcb. But I was only partially successful and now I have 2 sections of the panel that are unresponsive. Maybe it can be recovered but I’m a clumsy amateur with electronics and I’m not sure where I’ve gone wrong!
If anyone with more competence than me feels they might be willing to take a look I can bring it in at any time.
Many Thanks!!

Bring to Electronics night on Thursday? 7pm

Thanks Andy.
I can’t make this Thurs but I can the following Thurs (12th). Cheers!
