Tracing the pins 1 & 2 from the optocoupler I found that pin 2 is directly connected to the collector of a transistor 2SD1302...
Checking with the schematics there is no such component. There is KTC3200GR ?!
I've already checked their datasheets, and they are way too different in terms of specs...so should i follow the schematics and replace the d1302 with c3200 or ?! 😕

Has someone replaced it before? That transistor would have to withstand nearly 100v and it's only a 20v transistor.
Use the 3200 if you have it. If you don't, use a transistor rated for high voltage.

Can't actually say if it was from the factory like this or somebody has changed it before. There were some not very good looking repairs done before me, so maybe somebody has done that...
Changed the 2SD1302 --> KTC3200GR ---> Holy Grail ! Success ! Win !
Works great now ! Many Thanks Perry !
