    I have a Tivo Premiere XL lifetime replaced with a 2tb drive and the fan isnt working. Works fine but worried it will burn out. Swapped fans and power supplies. No luck. Any suggestions?

    On the Premiere, the fan header has a trace running to Q13 and Q14. Perhaps it's the same as on the XL?

    Thanks for the response. To test it,should I strip the fan wire and touch to q13 and q14. I assume if it spins just solder it?

    No, trace back the circuit and try to understand it. See if you can figure out what those TSOT devices are. Check the header with a meter. If there is no voltage, trace everything back. Perhaps the TSOT device went bad or something controlling it. I don't have an XL, and the motherboards are different.
