I have an RCA/Curtis RTU4300 4k tv that I lost the remote to, and I tried 5 different universal remotes with no luck, and an internet search has shown that I am not alone. In the manual, all I get is that it is NEC protocol with a universal remote code of A05F and then a 2 digit hex for each button, such as 5F for Power. I attached a screenshot of the manual.
I can not figure out how to use this, and I can't find info anywhere, as it all seems to deal with learning the codes from a regular remote, but not making them once the remote ihas already done a runner..,. I THIINK that I just put my code in front of the hex, such as "A05F 5F" for power, then convert to decimal? However, I get a 10 line number using the yamaha nec to decimal converter.
I am trying to do a universal remote with an ESP8266 to control my tv for now and maybe expanding in the future. How do I go about doing this? Primarily I just need volume, menu, direction buttons and some number keys to get into advanced factory settings. Thanks!
I don't know the specifics of NEC remotes, but

I do not have any specifics on NEC remotes, but I did find this:

Any chance of a link to the "yamaha nec to decimal converter" you are referring to? Googling it didn't return any useful information.
Thanks for that link. I was hoping this would have been s bit simpler, and seems as though I was quite wrong haha. I've tried combos of irsend.sendNEC(0xA05F5D); after seeing 6 digit capture codes and just inserting my info, but no luck. Amazed I cant find how-to's that don't require the original remote.

Hi there buddy, It's been a long time since you posted this. But I might have a solution for you question if you wanna try.
The remote you are using use an 8 bit address along with the 2 digit hex for each button.
You can try the address as follow:
You can try codes likes this; SVL 42 Celerio TV Remote IR Codes - Google Docs
A simple IRremoteES8266 is available for arduino IDE. You can use it.
Hope it helps.
