We get the codes from the Fetch remote guide (last updated November 2017) which for TCL have already been published by a user in this thread.
If they don't work, please contact Fetch as unfortunately this is not something we can assist with.
Hisense codes are: 1363, 1314, 0208, 1026, 1073, 0698, 0891, 0780, 0009, 1069, 2098, 2341, 2371, 2658
Complete waste of time enrolling to the YesCrowd as all I ever get is 'no's.
No response to the TCL codes in 2 years.
I've given up on both TCL and Optus now.
Why bother? It's just a fake marketing tool.
It does look like Fetch have changed their Contact Us page since that post.
If you have a Facebook account, they respond to customer enquiries on their Facebook page.
The Fetch Remote Guide last updated 2019 has an updated list of codes.
If you still need assistance with this, if you have a Facebook account, they respond to customer enquiries on their Facebook page.
If not, via their website.
