I have a Hisense 50H7GB1 that I haven't been able to fine discrete power codes for.
I tried using codes for TV model 65H10B2, however neither worked.

I suspect that Hisense has no discrete power codes. However, there is a way to try all 256 possible codes. If the codes exist, you will find them using the procedure below:

- Save 3 copies of your existing Hisense rmdu file
- Make Functions using OBCs 0-100 in the first file, 101-200 in the second and 201-255 in the third and assign each to a button (Buttons tab is the easiest place to do this). I usually give them the same name as their code, i.e., OBC 179 would be named 179
- Add these three new devices to your rmir file and upload to the remote
- Pick each device and try every button. You can skip OBCs that are already known if you wish.

Make sure when you test that the TV is in the appropriate initial state. For example, to find discrete on, your TV will need to be off before you try the code. So it may require a few passes to fully test each code.

It is possible, but unlikely, that you will run across a code that resets your tv or puts it into some sort of service or test mode. So be aware of this risk.

This is what we call a brute force search and is the primary way unknown discrete codes are found.

Good luck, and please let us know if you find any new functions. I'm sure other Hisense owners will be grateful.

Any update on this?

I'd be very interested as well, I just purchased a 2018 75P7 (Australia) and cannot find any codes which work. This pdf here has codes: ([Link: hisense-usa.com]) but did not work for me, must be from an older range of TVs. I've called and emailed Hisense but haven't got anywhere yet.

I love this site!

I finally was able to find a code to work with a charter remote and a 55 in hisense roku tv...

TV Code: 12355 or 12049
Pace Cable Box: 01982
OK/Select Code: 00231

The KEY for me was suggested up above for programming the OK/SELECT code - make sure tv is off while programming.

"Make sure when you test that the TV is in the appropriate initial state. For example, to find discrete on, your TV will need to be off before you try the code. So it may require a few passes to fully test each code"

Then that remote doesn't accept advanced codes. I have tested 00245 on a remote programmed with tv code 12049 on my Roku tv, it worked. I mapped it to different key then ok key. Because my ok key worked perfectly.

You might think of new remote like the Walmart Onn universal 6, it take advanced codes like what posted in this thread.
