Thank you so much for answering! Unfortunately the Hphase only moves the image position horizontally on the screen, not the image itself (I thought aswell that it was a RGB Centering matter). I’ve just noticed that in the service manual there is another parameter that I need to move in order to center the image, but I couldn’t find it (I’ve opened it up searching for knobs inside but I couldn’t find anything). Do you/anyone have any clue on how to do this? (the matter is explained in the image attached 🙂 )
