These are Jesus days...I found the problem. From beginning I replaced: - entire recap (solve flickering); - replaced flyback (nothing); - replaced ceramic capacitor in the neck board C206 (nothing); - replaced transistor on the neckboard, TR201-202-203 (nothing); - replaced ALL variable...

It's strange because the same connection with CA&G VI2100, Tatung VT2040, 2 MTC900e and MTC9000 clone (similar component distributions) work correctly. No earth issue and clear image.

I replaced all transistors BC558B, BC548B and vertical deflector TDA1670. Nothing to do, same issue.

I have a chassis with a first version of MTC 9000 with small white points in the screen, brilliant effect. (below a youtube video) I tried to: - replaced all electrolytic capacitors, total recap; - replaced ceramic capacitor in the neck board C206; - replaced flyback; - tested with another...
