Dead Macintosh CC :(

[amstrudy]

I posted a while back about a Macintosh CC that came into my posession with serious corrosion. Someone gifted me a board that needed recapping, and I finally just got it back from maccaps. I plugged it into the machine, heard a slight whine noise, and got absolutely nothing when turning it on. No fan, no chimes, no nothing. When I take out the board and turn on the machine, the fan does turn on. Does this mean there's a short in the board somewhere? The guy from maccaps assured me that it was working when he sent it back. What are the next steps? Thanks!

EDIT: There is currently no PRAM battery as I am waiting for one to come in the mail. I'm not sure if that's a major factor?

Are you pressing the soft powerkey on the keyboard?  You need to do that as well as the switch on the back.

I don't currently have an ADB cable, but I am ordering one now. I've been thinking that the soft power should boot the thing, but the fan should start when the switch on the back is turned on, right? Is there any way to force a boot without the keyboard?

EDIT: If I push in the logic board while the machine is on (and the fan is running) then the fan stops. Sounds sketchy to me ...

No.  The noise when you hit the switch is normal, but the fan doesn’t start until the soft power is pushed.

also, svideo cables work for ADB

Ok, thanks for the info. I have a USB to Svideo/ADB convertor. For quick testing purposes is it possible to use a USB keyboard to power on the CC using this convertor?

 

[IlikeTech]

It is a usb to Svideo adapter?  Or is it an usb adb wombat 

 

[amstrudy]

Not sure. Here’s a picture.

Looks like a USB to PS/2 adapter.

Ohhhh I see it isn't the right adapter. I will go order an ADB cable then!

You can use any odd S-video cable if you have one handy...

 

[amstrudy]

Yeah, someone mentioned that earlier. I don't have on handy unfortunately.

Update! She turns on! Now to boot...

The CC fans do not come on when power switch is turned on with Logic board in.  You need to push the soft switch.
