Something must have changed, I just took out the Inteset 422-3 remote, made by UEI the makers of One-for-all remotes. Entered code 12049, while my TCL 43" Roku tv was on LiveTv, I have no antenna but there are bunch of free channels. The 10 key pad now works, it put up the same blue numbers as always but now it actually switches to that channel!!
You don't need to send to UK for a remote, look for the Inteset remote on amazon:[Link: amazon.com]
Or ebay for the One-For-All urc-7880: [Link: ebay.com]
