worked again on the set,, the diodes are fine, replaced T5, no real change. I swapped the 2SB51 with one in the vertical, somehow, an improvement, the sync is much better.
I realized that all 3 controls interact a lot, sync, frequency and drive. only one thing, the picture cannot be centered properly!?!?.
I could not find the reason why I needed to change the C101 to a much lower value but so be it, I have removed the PCB so many times, I must say that although this set is very sensitive and controls must be set properly, it is somehow robust, except for the poor quality of the copper on the PCB, the rest of it is rather solid and sturdy.
thank you for all your help, now I will work on the European version, it should be similar, I don't have the schematic for that one but it is in much better shape, I have raster and only the vertical has issues, I think that changing the lytics should do it.
