Help with Macintosh plus!

[Mac plus/se30]

I recently received a Mac plus, it appeared to have a fan mod but other than that nothing done to it, but the crt will not come on, and when I tried to reflux it it still would not turn on, and had a low flup flup flup noise and still would not turn on, I found the scimarics of the anolog board and found non of the voltages on the board mached, idk what to do , just give it to me straight, is it going to be a cheap fix or is not fixable, thanks

Howdy!  Welcome!

Sounds like the analog board needs some new capacitors.

Grab a copy of the Dead mac Scrolls and check it out.

Well what exactly have you done to the system?

Have you replaced any components?

No I have not, it’s looks Like it’s been recapped tho

Is anyone still out there that can help?

Have you made sure that everything is hooked up correctly between LB, A/B, CRT and Neck Board? If so, at this point I'd think posting high res pictures of both sides of the A/B and Logic Boards would be in order. Details of the fan mod might give some clues as to what might be awry as well.
