The ticking may indicate the power supply protection circuitry detecting an overload somewhere and shutting down momentarily, lather, rinse, repeat.Hello:
I've got a Tivo Series 3 HD with a bad power supply which makes a "ticking" sound when plugged in. I replaced the capacitors listed in this guide:
After doing this, it still ticks and the Tivo doesn't power up.
Any thoughts on what other components I might be able to replace before I need to just replace the entire power supply?
Or it may be something on the power supply itself.
Double check your soldering to make sure you didn't "bridge" anything.
Double check that you got the polarity on the capacitors correct.
Then try it with nothing connected but the power cord (no Ethernet, no USB, no HDMI or analog audo or video out, no cable or antenna in), no cable cards installed, and the hard drive disconnected.
