OK - I know this has been covered before but thought it worth bumping after a new experience.




So I was meddling with my Tivo and pulled the power cord from out of the back of the Tivo.




After meddling with all my gear I connected aerial, USB, Hdmi then stuck the power plug back into the Tivo. Got the dreaded Flashing Green Light of Death.




Unplugged everything, let the drive sit for a few hours and went through the same process. No surprise same result. Flashing Green Light of Doom




Googled all the "Tivo Flashing Green Light " threads and seemed like a fix was the old hot air blower over some chips. Not a simple fix for me since I am a bit tight for space getting the Tivo cover off and running the hair dryer. 




Thought I would try a different approach.


- Unplugged every thing off back of Tivo


 - key step!. Switched power off at wall and pulled power cord out of socket.


-  Let Tivo Sit for an hour or two (not sure if this step is needed)


- Plugged aerial, HDMI, USB and power cord back into rear of tive


- Plugged power card (with power switch off) pack into power socket


- Switched power switch on at socket


RESULT = solid green light 




Yah - Tivo back working again. Not bad for a modded older beast!

I think the secret is to unplug from the wall for about an hour .  I suspect it's to let the capacitors discharge completely.

I'd say you got lucky. Unplugging for an extended time may help, but from experience the problem will likely be out of tolerance RAM chips(s) and may return next time you have a power cut, or a time after. Heat applied to the RAM chips via a heatgun will usually get you back up again until the next power cycle, but the amount of heat needed varies quite a bit. You may have to try several times before success. Hynix RAM chips never seem to display this problem (if fitted) and some other brands do. Replacement probably isn't economic. I have hot air gear, but when a used replacement Tivo is around $20 these days, it's hardly worth the effort. 

Tivo upgrades to operate with the new OzTivo EPG, support and service. Over 300 performed here so far. See:
