Samsung, cablevision and tivo - weak or no signal message

SOURCE: program the remote

try the auto scan feature explained in the instruction manual for the remote

SOURCE: Tivo won't change my TV Channels anymore with direct cable

I re-did the guided setup in the Tivo under Messages & Settings/Restart-Reset System/Restart menu section in Tivo. Once I did that, it cleared this issue, even though I didn't have to change any of my settings thru this guided setup. I tried a reset alone first, but that did not fix it. Only this fixed it. We had lost both power and cable during a recent tree fall in a storm, and when both were restored, this problem started. I have a cable coax directly in the back of the TV (no cable box/IR etc) and the system is on a home wireless network. I actually have 2 identical Tivo's in the house set up the same way but only one had this problem. The other worked no different after the outage.

A similar problem happend to me. Buying a new remote fixed it - for about three weeks.

Maybe your new one will work longer.

Set up your infrared blasters connected from your IR port on the Tivo and by placing the two lead lights in front of your cable box so it (the cable box) can read the signal.  Then go to Channel settings accessed through Tivo Central and follow the questions. It will ask you to change channels until the remote is working correctly.  This all worked on a different "input" on my Mitsubishi TV (it has multiple inputs.  I have the cable input on a different "input" to make it work.  Hope this helps.  Call TIVO tech assistance because they are the ones who talked me through this.
