I’m trying to configure the TV Source/Input button on the GTV-IR1 remote that comes with the Formuler Z10 and am running into issues. I’ve successfully set up the power and volume buttons to work with my TV using the learning mode, but the Source button doesn't switch input sources like it should.
When I previously set up another universal remote with this same TV (it's an Insignia / NS-55D440NA14), I had the same problem and ended up having to manually configure the IR codes for the source/input function. From what I understand, the Formuler remote doesn’t use IP codes, so I’m stuck trying to figure out how to make this work. This is particularly frustrating because the source button is the only reason I still need to keep my TV’s original remote around. I’d love to consolidate everything to the Formuler remote if possible.
I’ve already reviewed the following threads, but unfortunately they refer to the BT or an older remote model and haven't helped me: Source function on remote, Bluetooth remote control, How to program Source button on GTV-IR1?
Thanks in advance for any guidance.
