hey all, my kid powered off and on and off and on my series2 tcd140060 via the power strip switch (he's 4yr old) and i get a black screen, no boot. i removed the cover and found the harddrives werent spinning up. i used an AT power supply i had just for the molex connections and the drives spun up fine. however i think the tivo power supply pooped the bed to the motherboard also. only the fan spins with its own power but still black screen and the two lights in front like a normal boot-up but this is for over an hour with no grey screen "please wait for a while" just black screen. weaknees has the PSU for 50 bucks and i think i will try since i have 250.00 in lifetime non transferrable subscription to that box. i gather i cant take out the drives and install them in a new unit since the serial#s won't match voiding my subscription if i am understanding how it works correctly. if my symptoms sound familier and you have replaced the psu and it worked please let me know and i will get one tomorrow if anyone knows if i could just pop in the drives into a new tivo unit and continue my current subscription legally, please tell me!! since a new series 2 is only fifty bucks, the same price as the power supply. thank you all whom took the time to read this thread Steve. p.s. the TiVo in question is in my sig link for the upgrade i did.
