Yep. Time to pull out a copy of Tech Tool Pro v.4, Norton Utilities v.3.5 or the Hardware Test disk that came with the iMac, if you have them. If not, PM me and I'll see if I can burn you a copy.
If it turns out to be also the PAV board, it kinda doesn't surprise me that much. That Mac is going on 13 years old and with how many times it's been powered up, restart and shutdown can put some stress on the HV components. You might be able to look here or on eBay for a matching replacement board. I'll look around and see if I have the service manual for tear-apart diagrams and diagnostics.
