Sony C37P DC/DC Converter Problem.....

[la-2a]

Hello people, I'm in the process of bringing a Sony C37p back to life. I suspect the error (too little level) in the DC-DC converter. A question for the experts. Can anyone confirm the correctness of this circuit? Somehow I don't quite understand it. The conductor tracks don't quite correspond to the circuit diagram either. In addition, there are no names printed on 2 components that should actually be diodes. Unfortunately I can't measure anything even when it's removed. I marked it in the photo. I really appreciate your help and would be happy to be able to solve my problem.

Yes, it would make total sense for that to be another diode.
