@droodle, it might worth jumping onto Whirlpool and asking there.
I've read a couple of threads on the topic and there are customers reporting that the Sony code worked for their TCL branded TV.
Has anyone come up with any updates or a solution for the remote codes yet?
I just bought a TCL 2018 model for the kids and can't get any codes to work with their Fetch tv box.
I've been waiting for a year now ans nobody has posted any news on this.
The Optus people simply say nice things but do nothing.
Like a recorded message using a real person.
I live in hope that my Dec 2017 TCL TV will one day communicate with my Dec 2017 Fetch box.
Amazing how nothing ever seems to happen to find solutions to these issues or provide an explanation as to why nothing can be done. I have a new 2018 TCL and no joy with the Fetch Mighty remote.
