Hi everyone,
I’ve been lent a Macintosh Classic II that seems to have had very little use. I’m in Spain, where the mains voltage is 230 V. It probably has the typical capacitor problem, I assume. When it powers on, it doesn’t manage to show an image — I’m attaching a photo of how it looks.
I opened it and cleaned it thoroughly, and surprisingly it didn’t have much dust. I still haven’t removed the socketed chips or the memory modules to clean them properly — I’ll do that soon.
You can see a video of it powering on at this link: https://streamable.com/h1w9ef.
The photo shows how it was starting up before the first cleaning, and the video shows how it starts up now.
I’d like to know where to start.
I suppose the first step is to replace all the capacitors, although I don’t know if there’s anything specific to keep in mind with this model.
Do you know if it’s necessary to do any kind of repair on the CRT?
I appreciate any advice. Thank you very much.
Jorge.
