I am working on a 3D TV LG 47GA7900, working on External

Customer Question

HI, I am working on a 3D TV LG 47GA7900, working on External Control Device Setup. In the 47GA7900 Manual, External Control Device Setup, page 5 it claims the Communications code is ASCII code.
My example is from Page 7 of the External Control Device Setup Manual.
The manual leaves me lost, it is a mix of ASCII and Hexadecimal. So here is the question, is this correct a mix of ASCII and Hexadecimal, Turn on the TV Code:ka 01 FF20? Or is this correct turn on code, all Hexadecimal: 6B61 01 FF20?
If it takes time to figure out, you can email **************.

Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

The 'K' could not possibly be hexadecial. Hexadecimal letter notation only goes from A to F. Not G, not H, not I, not K.

So: That 'KA' is presumably just that: a K, and an A.

Unless it's a misprint. ([*sigh*] obviously not a cheering thought.)

The 'correct' turn-On code, is probably wrong. It has five hexadecimal groups. But you can try it.
