Thanks to the advice on this board, I bought an old "donor tivo" on craigslist, and replaced my power supply. Much to my delight TCD240 was alive once again!!! BUT my joy would not last long. There is no response from any remote signal (I have the old peanut). - The donor tivo DOES respond to my peanut. - Yellow light on front panel never flashes. Just steady green. - Replaced front sensor circuit board with the one from donor tivo. Nope. - Replace batteries in peanut and performed both "resets". Nope. - I'm certain it's not IR interference. It's disheartening to have come this far (replaced hard drive, replaced power supply). But after 9 years of faithful service, maybe it's time to say goodbye to my lifetime series2.
