CC doesn't boor with lb, but without is starts (fan) - PLEASE help

Hi Guys,

 

I know there are loads of topics. But i still dont know what to do.

 

-So the CC wont booth with my keybaord.

-Replaced the PRAM battery with new one.

-CC 'boots' without the Logic board. Harddrives spins (sound), no green light, no screen working.

-Logic board in, without Pram battery doesnt boot either.

-Didi the power in for a day, with switch on, nothing...

 

The logic board looks really good condition. No corrosion or anything.

Just a little bit dusty.

 

 

Do i need to clean the bord? I see board in water??? Sounds insane, but will that help.

 

Thank you!

So, when you flip the power

So, when you flip the power switch on the back of your Color Classic, the hard drive spins up even though there's no motherboard installed? That's not normal at all, and suggests you have a problem with the analog board. The drive and rear fan shouldn't start until the keyboard power button is pressed (with a working motherboard installed, obviously).

If you need to clean the board, use isopropyl alcohol, not water.

Yes, the fan strats, the hd does a spin... and thats it, when pushing in the logic board, it shuts down, or other times it stays on and nothing happends, and one time i heared the pram eroor, but screen stays blank.
