Mac Classic II Squeaking

Mac Classic II - The Squeaking Problem.
My "new" Classic II has a squeaking sound coming out of the case. Morphing into a very high frequented sound, annoying.

Does anyone know what is the problem with this Mac ?

It seems not to be the speaker (my first tip) because I removed it and the Classic still squeaks. I changed the Motherboard and the squeaking stopped. It seems that some of the capacitors on the Motherboard have not made it through the years.

The system on you Mac is defect or can not be found.

If you have the System Installations Disks try the "Disk Utilitys Disk" to boot the Mac, find "First Aid" on the disk and try to repair it. If that does not help, install a new system from Floppy Disk and it should work again.

I had the same problem on my Mac Classic II for some time, but after an hour or so the noise would stop ... I assumed it was because all the components had warmed up. I did not use the Mac for about a year and a few months ago when I switched it on the display was faulty ... mainly black with white stripes of variying length. I'm grieving for it, it's like losing an old friend. I assume it has power supply (EHT?) problems.

Hi, it sound like my problem. The capacitors on the mainboard are defect - they reduce the internals sounds on the board. They have a lifetime about 10/15 years and now going to die. Many Classic Macs get the problems in these days... Only one chance - replace the capacitors with new ones.

Hi, Your diagnosis seems reasonable for the noise but do you think it would also account for the screen 'blackout'?

Did your problem get resolved by changing the capacitors? If so was the work done by an agent or yourself. Also I assume there are many capacitors. Any particular ones changed?

I replaced the Motherboard :-) I still havn´t soldered on the MotherBoards - but it seems I will. You should chage all capacitors because if one dies all will. They have different voltages - I still look for a good list for the used capacitors... Can anyone help ?

My Color Classic just developed the same exact problem - at first I thought it was a failing hard drive. Upon closer inspection most of the electrolytic caps on the motherboard are toast - I will be replacing them with tantalum caps from DigiKey.
