Problems with Sony SLV-E600B

[Jmarcusse]

Hello,

My old, but not so tired magnetoscope is without picture. But song is ok.
Alimentations seems good with voltmeter.

I need drawing to go inside with my oscilloscope.
Does somebody can provide me all the drawings?

What do you think about losted codes ? In this model, is it possible?
How to write them again?

Thank for your technical proposals !

Best regards, JMarcusse in France
