If the usual PRAM/power manager resets don't work, it's time to trawl the 2400c mailing list, and research the repair of the SMT fuses (IIRC there are about six that can fail).

I successfully repaired two 2400c by replacing two SMT fuses on the motherboard, in different locations on the two machines. The fuses were fairly easy to obtain from an Australian electronic component reseller, but I had to get a friend to buy them for me as had an ABN/could set up a business trade account with them.
The 2400c I kept has had no issues with the fuse repair - it's specced to 240Mhz G3 112MB/40GB HD. Oh, and there is also the Cardbus modification which is pretty easy to do as well. YourMacStore in California still sell the 96MB RAM module for USD $59, which isn't too steep, in my opinion.
