"Repairing" a TiVo (if the problem is the motherboard and not the drive, fan, or power supply) these days consists of swapping it for another one.
I doubt there is anything to repair because I seriously doubt anything is wrong with the current TiVo to begin with. Read between the lines of the OP. A shiny new model came out and he wants it. He doesn't seem to care about getting his TiVo "fixed"; he wants a Roamio Plus.
Best Buy is out $200 and TiVo is out $500 for transferring the Lifetime service to the Roamio. I deliberately linked to that BBY forum post. Evidently plenty of people view buying extended warranties as a way to upgrade to newer and better models for practically nothing.
