You are saying to resolder that two points.Welcome to AAC!
At least to places on the PCB appear to have lifted traces and possibly a broken wire on the lower one. It looks like someone tried to repair the board but didn’t do very well.

Not exactly. I am saying to repair them. I can’t tell why the lower one was jumpered using the lead, nor why if it now apparently broken, and I can tell if the upper one can be resoldered or if it’s pulled off its pad.You are saying to resolder that two points.
I will resolder it then try.Looking again at the lower joint, it certainly has the appearance of melting open which would be a symptom of some Other problem and not a cause in itself.
May I know transistors used in this circuit PNP or NPNI will resolder it then try.
