I have a macintosh color classic, a very nice and clean piece with no rust dust or any molding anywhere in it.. the only issue it has it is it doesnt turn on.. ive stripped it all down and cleaned it all up.. when its fired up without the logic board, it turns on fine, i can hear and see the fan running, i can hear the hard drive spinning well good.. it just all sound good but nothing on the display.. however when i put the logic board in and turn it on, i dont hear any fan or hard drive sound neither anything on the screen.
I have researched and theres only a very brief help on with this specific macintosh model as its just very rare.. I have read online where the guy advised to clean the logic board connectors to the other parts inside.. did that very well, replaced all capacitors, cleaned the connector inside the machine aswell. tried with or without PRAM battery, tried it with swapping the ROM SIMMS around, tried with the ram chips around.. still no help..
its very strange as it turns on without the logic board and it doesnt with it so it is the logic board for sure, and while the macintosh is running, i tried put the logic board in then and i do see the green light turning on at the front but thats still no help..
the motherboard is actually very clean compared all the other macintosh's ive dealth with in the past most probably because its the newer model then them.. see the image attached and any help would be deeply appriciated.. please dont ask stuff like whether ive left the machine on for a whole night as ive already read about that because it really doesnt help ..
Thanks
