    Macintosh Plus. Very vertical image at startup

    Comparatively, between a Plus working and the Plus with problems, there are no differences in the voltage of the J1 cables: Red and blue = 5.10 V, Yellow and green = 0.12V from power on to 10mn of use.

    Macintosh Plus. Very vertical image at startup

    It is I who apologize, sometimes my answers are a little evasive, not precise enough and I thank you for your attention to my problem. What type of voltage should I find on J1? How do I adjust my multimeter? What cable should I check? I cannot change the FlyBack: that of my analog card is not...

    Macintosh Plus. Very vertical image at startup

    Thank you very much for your quick response. the welds were checked. It has also been tried with another cable. the cause of the defect must be something else, I suppose. Could this be a flyback problem? Because as it heats up the image stabilizes. thank

    Is there a schematic or an image where you can see all the references of the capacitors to be changed?

    Macintosh Classi II. No sound

    Thanks for the reply.   I am not an expert and I am afraid to cause a big fault.   I prefer to change only the necessary ones. In the future I will change all.   Best

    Macintosh Classi II. No sound

    Thanks for the answers. The computer works fine, only the sound fails. Could you tell me which capacitor would need to be changed to fix the sound?   I think it's not necessary to change all the capacitors Thank you.

    Macintosh Classi II. No sound

    Hello again everyone,     Greetings from Spain.   I have Macintosh Classic II; Is fully operational except sound. In the past there was sound, although it emitted hissing. Now there is no sound.   Could the reason be some specific capacitor?   Should I check another reason before?   I should...
