Hi, Greg. Other replies are right pointing you to the motherboard. I would try the following in this order (from easier/faster to more difficult):
1) Take out the RAM SIMMs (if you have them). Try to boot the machine without the RAM - the Classic II has 2 Mb of onboard RAM, so if the RAM SIMMs are faulty, it will work without them. If the Classic II boots without the SIMMs, you have got the problem - try to clean their edges with an eraser, and if they don't work after cleaning, stay without them or go buy another pair. 2) If you aren't able to boot without the RAM SIMMs, try to pull out the ROM chips (the four large chips located in one of the corners of the motherboard) and reseat them. When you do this, take care to put the chips in the same order and position as they were before. 3) If the Classic II still refuses to work, wash the motherboard. Take it out, remove both the RAM SIMMs and the ROM chips. Then wash it by hand with warm soapy water and a toothbrush - some people do this in their diswasher, but I think that high presure water can damage surface mounted components. The objective of this is to remove the sticky goo from the surface of the motherboard, so use your toothbrush mostly in the dirty areas of the coard. When it is clean, let it dry at ambient temperature. Do not use an owen of any kind, and do not put it into the sun - those could damage the board easily. Let it dry for at least 24 hours, more if you live in an humid area (otherwise, moisture can still be trapped under the components). When this time has passed, you can put again the SIMMs and the ROM chips and plug it in your Classic II and see if it works. It would be nice to know of your progresses :-) .
