I have a motorola DCT3412/2305 set-top box and a light silver remote with red ok button.
Remote has been working fine for ages now all of a sudden it's not. Remote still works fine for TV. I see light emitting from the remote through my phones camera. Tried using a few of the codes mentioned within this thread (01376 01982 etc.) but they aren't working for me. I don't remember the code I used to unlock it but it seemed to be locked because once I entered it in I got 4 blinks on the CBL button. I then proceeded through the set up codes again, and although every 5 digit code I put in gives me 2 blinks once done, the remote still fails to respond. I've also tried doing the resets (980 and 981) but not sure if they took. I read 3FG saying it was the last thing to try.
Anyway, I'm now thoroughly confused.
I haven't seen the model number for my box within the thread so I figured I'd create an account and post a reply to ask if there was anything I'm missing.
