Color Classic Sick :(

Recommended Posts

I got this Color Classic about a year or so ago. It would start up fine but it had this weird issue with the screen being one color until it warmed up a little. I decided to pull it out today and fire it up to see what would happen. I recapped the motherboard last year also.


Here is what I found out:

1. HDD Spins up, Chimes, Red Screen

2. Blinking Floppy (HDD must be dead now)

3. 15 seconds or so later, Sad Mac 0003


Turned it off and tried again:

1. HDD Spins up, Chimes, Green Screen

2. Blinking Floppy again (I think i'm going to find a floppy to boot this thing with)

3. Sad Mac again.


Found a floppy, but it didn't like it. I think the version is too old. The startup and death chime started to sound a bit odd after a few attempts. Maybe just my imagination.


Here is a video I recorded:



Obviously first thing I need to do is get a startup disk and see if it will actually boot from floppy. Whats with the sad mac though?

I was able to boot from a floppy. Sure enough it wasn't able to detect the hdd. I shut it down. Took out the motherboard to look at it. Put it back in. Hdd decides to work again... Monitor went from a yellow tint to normal after running for a bit. Hard to tell, but there is some flickering that comes and goes.

My color classic booted to a purple screen one day.  I sprayed some contact cleaner into the pots that are used to adjust screen size.  I have a tool that I can stick in the pots to turn them.  After I hit the pots with contact cleaner, and put my tool in, the purple screen went away.  I noted the position of each pot.  Then using my tool I turned each pot all the way to the right and left several times.  Then I returned it to the correct position.
I am sure you have other issues (bad solder joints?).  But it is easy to buy some contact cleaner and try this for starters. Just an FYI
