EFCs for Roku (TV version)

MaskedMan · Post by **MaskedMan** » Fri Jun 09, 2023 12:31 pm

So, this will be end of me searching Roku TV efc's, I just ordered a Amazon Fire tv Omni 50" QLED tv. Should be here Tuesday the JUN 14th. The Insignia Roku tv has already been replaced with Samsung 4k 75".

According to my IR tester, the Roku remote included with my Hisense TV uses a Goldstar code set. The tester also reports that its OBC hex codes are all < 80 and it reserves the high bit for a sustained key press.

On the UEI C4000 (for Spectrum), TV# 12183 uses the same code set so I decided to mine it for missing key functions.*

For those keys that I have OBC hex codes for, I have a map/algorithm to convert IR hex to an EFC. It works for every device that uses 6122 & 6122A formatting (so far).

FFwd had a different key** than my OEM remote, but I just loaded the correct one on top of it.

00235 FFwd
00169 Replay
00054 defunct shortcut
00058 defunct shortcut
00251 Spotify
00168 Sling
00166 Showtime
00170 Prime Video
00037 Vudu
00041 Rdio
00043 Vudu2
00036 Netflix
00105 Max
00103 YouTube
00228 Hulu
00197 defunct shortcut
00201 Play Station Vue
00199 Starz
00203 defunct shortcut
00196 YUPPTV
00200 defunct shortcut
00198 defunct shortcut
00202 DirecTV
00069 Crackle
00073 Paramount+
00071 Roku
00075 ESPN
00068 defunct shortcut
00135 Power Off (only)
00134 composite video
00004 HDMI 1 (ARC)
00008 HDMI 2
00006 HDMI 3

I have two OBC hex codes which are acknowledged but have no obvious effect on the TV:
IR hex 71 = EFC 00137 &
IR hex 7F = EFC 00010

And I have found no EFC for the antenna input by itself.

*TV# 11756 works for most Roku functions, but being a Vizio? code set, without OBC hex samples, it is harder ferret out missing EFCs.
**It [EFC 00038] had the unexpected effect of turning the audio & video off on antenna channels until a channel up or down was performed. The TV remained on, otherwise.

Actually, your Hisense Roku tv responds to two completely different IR code sets, the Goldstar matches the Hisense IR remote, but it also responds to UEI code 10463 which originally used by Admiral, Dynex and Sansui tv's.

Hisense & Sharp are the only Roku TV brands to use the Goldstar code set. All other use Admiral code set, and they include Tcl, Insignia, jvc, Philips, InFocus, Onn, Westinghouse, Magnavox, Element, Rca, Hitachi, Haier, and Sanyo Roku tv brands. So, a Hisense Rok tv IR remote wouldn't work on any of the above Roku tv brands, but all the above Roku tv remotes would work on your Hisense Roku tv.

Test all codes listed under Dynex in your C4000 Spectrum remote, it's the only code set Dynex ever used, unlike Best Buy's other house brand Insignia, which has used many code sets over the years. Then test efc's.

I have not tried 10463, yet.*
11756 has all but one useful keys, but no channel numbers. It appears to be a Vizio code set, correct me if I am wrong.
I only had to add two keys to 12183, but I added others.

*I have no OEM remotes to compare 10463 & 11756 to.

For 10463, Up & Down were duplicates of Right & Left and it had no player controls.

(I did not try the channel numbers.)

You mentioned on remote central your remote didn't have code 12049, but it's listed in the c4000 remote manual, that's a better code for Roku tvs.

You offered 14398 (which did not work).
12049 looks promising, but I have no OEM version to compare it to.

For 12049, all keys worked except Pause & FFwd (just like Goldstar #12183).
Last = Replay.
Pause = Replay2.

Pause can be copied from Play, but I need the correct IR hex or EFC for FFwd.

Do you have a working copy of the remote and an IR detector?

Now, TV# 11756 does not work. The Goldstar [12183] & Admiral [12049] codes still work, but 11756 only turns on the TV after a system reset and nothing else...

My TV settings say that it had a software upgrade yesterday.
I do not know if that accounts for the Vizio [11756] code set not working, but a second OK key [EFC 00055] in my Goldstar [12183] set is now the decimal point for OTA channel selection.

Yes, I always suggest code 14398/4398 for Roku tv first, it has the most efc available for Roku tv's.

Newer remotes have new Roku tv code that only works on Hisense and Sharp Roku tv's, that code is 14740/4740.

My Spectrum universal did not accept 14740.

More for Hisense/Goldstar, #12183,

00137 Power On (only)

(That was the unresponsive OBC hex 71 that I mentioned in an earlier post.)

Think about upgrading your remote, the Onn 6 is pretty cheap and has both 4398 & 4740 on board:

This one will do for now.
