Not so much a repair log but a bit of information.
The system booted to either a blank screen, to a blue screen with a couple of bits of garbage or to a screen full of random garbage
Pulling the SID chip let the C64 boot normally.
I always pull the SID chip when starting out testing for this very reason. Not sure why it does it but it can cause problems like this.
