Try resoldering the crystal besite the micronas chip, or if you feel adventerous swap one from another TiVo. I've experienced what you are describing and it is either dry soldering under the crystal or a dud crystal - sometimes heat sensitive.

Still, no great loss, have a wonderful collection of spares for the other TiVo's now
Shame if this is the case. Hate to see a good TiVo go bad. If you ever want to save it let me know. I'd actually be interested to know what went wrong with what should have been an easy mod for someone with your calibre.
