Im not sure if i missed it in the thread but are you able to show the checksum calculation formula it appears to be a completely different formula from commercial grade screens.

Thanks,

I'm not sure how this will look on the forum, hopefully it shows up correctly:

=DEC2HEX(HEX2DEC(100)-HEX2DEC(RIGHT(DEC2HEX(HEX2DEC(MID(D4,1,2))+HEX2DEC(MID(E4,1,2))+HEX2DEC(MID(F4,1,2))+HEX2DEC(MID(G4,1,2))+HEX2DEC(MID(H4,1,2))+HEX2DEC(MID(I4,1,2))),2)))

I decided to share what I have that partially works to see if it helps anyone. Please feel free to contribute if you see something wrong! The script works great sometimes and after the TV power cycling it may or may not work. If it does work, it works for the entire time the TV is on.

Code is here (work in progress):

I'm able to turn ON the TV with both the Power-On and Toggle commands, but unable to turn it OFF. Neither Power-Off nor Toggle seem to work.

TV: UN60F8000
Power On: 8, 22, 0, 0, 0, 2, D4 (works)
Toggle: 8, 22, 0, 0, 0, 0, D6 (works as Power-On only)
Power Off: 8, 22, 0, 0, 0, 1, D5 (doesn't work)

Any ideas?

The link doesn't work for me. I'm trying to gain control of the Smarthub features on a TV.

I have been using your code set for several years (THANK YOU!) but the new (Samsung 8000 & 9000 Series - 2016) models no longer allow direct navigation to Netflix or Amazon apps. Have you experienced this issue and if so do you have a work around?

Piggybacking on your post, I'm expecting a Samsung 2017 MU8000. Has anyone tried Duct Tape's codes (Thanks!) on the 2017's? More specifically the KEY_xxx ones, which I assume are the Smart Hub ones?

Dormant thread?

Here are the (only) commands that worked for me on a MU8000:

Power Off 08 22 00 00 00 01 D5
Power On 08 22 00 00 00 02 D4
Enter (OK) 08 22 0D 00 00 68 61
Exit 08 22 0D 00 00 2D 9C
Return (back) 08 22 0d 00 00 58 71
Menu 08 22 0D 00 00 1A AF
Info 08 22 0D 00 00 1F AA
Up 08 22 0D 00 00 60 69
Down 08 22 0D 00 00 61 68
Right 08 22 0D 00 00 62 67
Left 08 22 0D 00 00 65 64

BTW, the "KEY_..." set did not work for me.

And don't make the mistake as I did of adding a command termination suffix (0D 0A): in my setup, it made things erratic, not to say totally non operational.
