sounds like the analog board is resetting due to overcurrent, try recapping the logic board and analog boardIt won’t let me get it to boot up and it just makes a humming noise. The screen is black what should I do to get it to work
I'm certainAre you certain that re-capping both boards will fix the problem
Well.. It will certainly not work without doing this. If it is everything you need to do, you will have to find out.Are you certain that re-capping both boards will fix the problem
No I didn’t because I have not opened it upDid you measure the voltages at the floppy port?
There are a lot of parts on classic AB that can be defect. Most often: DP3 and DP4 (1N4148), TDA4605, CNY17G, IRFBC40. Could be that you have to replace some of these.
Recapping AB and LB should be done. Take the battery out of th LB.
What I am going to do is to have a computer repair technician open it up to remove both boards and send them out to a board repair companyNo I didn’t because I have not opened it up
Then it might as well be battery-bombed. The most reasonable strategy for you would likely be to trade your Mac to somebody here and buy a refurbished one instead..No I didn’t because I have not opened it up
Nope I will get it refurbishedThen it might as well be battery-bombed. The most reasonable strategy for you would likely be to trade your Mac to somebody here and buy a refurbished one instead..
Please explain why you are certain that doing a re cap will fix the problemI'm certain
Recapping is a required /necessary first step, but it won't certainly fix the machine, but it might. Other things can be wrong as well, but it is certain that the caps need replacing, as they always do on these machines and they cause damage by corrosion.Please explain why you are certain that doing a re cap will fix the problem

I appreciate all of your help but keep in mind that:To anyone who reads this thread I am not going to give you this Macintosh because I am going to have it repaired
Ok I am getting the boards re- capped for $175.00 plus postage and $95 bucks to open it up to remove and replace both boardsI appreciate all of your help but keep in mind that:
1. I am not experienced in board level repairs.
2. One of you mentioned certain numbers that must relate to certain electronic parts but I have no clue what they are
3. I prefer to pay a professional to make the repairs necessary
Thanks All
Why did you get it in the first place if this is what you’re going to do?What I am going to do is to have a computer repair technician open it up to remove both boards and send them out to a board repair company
ListenWhy did you get it in the first place if this is what you’re going to do?
It’s like you bought a classic car without checking under the hood, it got dropped off a trailer into your driveway, and now you’re wondering why it won’t start.
Then when people start giving you advice about the standard maintenance you need to do, you’re asking if each task will make it start when nobody knows what the damage or wear and tear actually is. And now finally you’re saying “I’m just sending it to a professional.”
