I was just able to pick up 2 Commodore 64 units. One
has monitor (1701) and
disk drive (1541) and works fine. The other Commodore (computer portion
only) has the Power light come on, but that's about it. It does not even
cause the monitor screen to be active. My question is, is there possibly a
simple solution as to why the C64 is not working? I have not opened it up
yet, and I'm not a real "techie", but I could do some simple internal
checks
if I knew what to look for. Thanks for any help anyone may be able to give
me.
Typical black screen problems on a C64 are 1) power supply 2) PLA 3) fuse
The PLA is described in this article:

Try swapping this chip between the two units and see if it changes things,
assuming the power supply is known to be good.
