What model is your tv?

_{Sent with GitHawk}

[lebhacker]

it is UA32H4303

[eclair4151]

Hmm not sure. Unfortunately i dont really have any way to reproduce. I wish i could be of more help :/
But with this type of stuff if 1 byte is off anywhere in the chain the whole thing fails and finding where things go wrong is very tricky to do in person let alone across github. You could start by seeing what is inside the bytes variable since thats where the error is coming from. Bytes should be a hex number but the script says its not, so i would debug through the program if you can and see why bytes is getting a non hex value

[lebhacker]

OK later on this day i will share all the output for the script maybe we can find out where is the problem

wait what? The pin doesn't even show up on your screen? Well there's your first problem

[lebhacker]

will try to fix it hope this is my only problem !

[chimpzilla]

it is UA32H4303

This model doesn't support IP control as far as I know. It's only 5500 series and above. Same true of J series I believe

[Mannshoch]

Have the same error on my UE55h7
I get a pin. After entering I have.

[eclair4151]

Hmm, unfortunately as i stated above i have no way to test or actively maintain this lib so your sorta on your own here. Sorry :/

[Mannshoch]

Found a workaround.
After TV prompt the Pin I have to kill the script and restart it.

The script is working if the Pin is prompted on TV when I start the script

[AngelofromTurin]

hi model tv h6203
i tried the script but response me:
current state stoped
pin NOT on tv...

[simonwanghub]

UA78KU6900JXXZ can support?

[eclair4151]

No that is a K series tv. check out this lib
