Macintosh plus screen centering issue

Recommended Posts

So I purchased a macintosh plus to fix my other macintosh (Which finaly after 4 months I figured out that the 1000 uf capasitors tolerance made them off set and didnt work correctly and that the tsm chips on both of my MBs are dead) so this new mac has started to have issues with the screen and voltage settings. The screen started to move to the bottlem left of the crt and the voltage was tripping the power and I would have to constantly change the voltage pot. So I ended up replacing the 2200 and 1000 uf caps. It fixed the voltage but not the screen issues. Even trying the horrisontal setting and vertical it would not move the screen back to the center. Im pretty sure its the fly back or the 3uf cap in next to the horizontal setting. But I want to know if anyone else has had this issue. The boot sound also sometimes drifts away too. Its sometimes quiet then sometimes loud. I cant upload a pic at the moment becuse my service is bad right now.

Did you try the centering rings on the neck of the tube? Those sometimes get loose over time and move around.

Those move the image diagonally when turned so it looks a lot like one of them got out of alignment on your machine.

Ok so thats fixed but I still am haveing another problem I should have mentioned. The brightness knob does not work what so ever and there is no cracks in the solider, the sound issues, and the focus ajustment barely works either.
