Advertisements Hi Everyone, For the last two nights, my Series 3 HD has been acting strange in that last night it stopped responding to my remote control. Yes, the batteries are good, the switch was in the correct position, and the remote has been cleaned internally several times in it's lifetime and is working perfectly (it was able to control the tv). Rebooting the Tivo resolved the problem last night, but the same thing happened again tonight. Rebooting the Tivo fixed it again, but for how long? No other IR in the room, etc. Nothing has changed recently. I just finished cleaning the remote (internally) again, but I know it can't be the remote if rebooting the Tivo fixes the issue. Right now the unit is working perfectly as if nothing ever happened. My Series 3 HD has a 1 TB WD Black Edition HD that has been working perfecly even after all these years. I have replaced the power supply once in the past. I'm guessing that some other component *may* need to be replaced at this point - likely related to the IR remote receiver. Soldering is not a problem for me. Does anyone know if this is a regular thing on Series 3 HD units after awhile? I did read through some other decades old threads on this topic, but they don't seem applicable. Any insight would be appreciated. Thank you for reading.
