[lukashalm]

Hello, does anyone find out what is the keycode for enabling In Start menu on LG's 2012?

i found undocumented code range 418-470 that has response 200
most of codes displays only message with X (http://i.imgur.com/neWjzKL.png)

So just to be clear, there's still no way to get into the service menus on the newer LG TVs?

[zer0ring]

I've a 42LA6230 & the best I've managed is:

NB: This script only worked for me from Windoze box running Python x86 when connected directly to LG Soft AP, steps below should get you connected just fine

1. Start Soft AP on LG TV & connect PC to LG Soft AP
2. Open script in Python & choose Run > Run Module
3. Enter the Pairing Key shown on screen into the dialog box (OPT: add to Python script & save for re-use)
4. Enter the codes above for the respective actions, but not the one and only thing I want: EZ_ADJUST;

My need is to enable Pass Through of 5.1 (6ch) audio from HDMI input to TOSLINK Optical output. At present any AV containing 5.1 sent to HDMI on the 42LA6230 TV is down-mixed to 2 (stereo) then sent out via TOSLINK Optical. Which means I can enjoy any media I want on my TV so long as:
a) I am happy to use the stereo speakers in the TV only, or
b) I am happy with only stereo audio on my HT surround system, or
c) I am happy to physically swap the TOSLINK cable from one source device to another each time I change what I am using

Answer to {a|b|c} = No

Many have stated that it is a simple on|off toggle in EZ_ADJUST to enable 5.1 pass through from HDMI to TOSLINK, but access to the service menu is required. I very much appreciate the work done to get this far, hopeful there may be something more we can do to expose/access the innards of LG TVs? I can't can believe they'd just hobble a function of the technology for market control.

For HDMI connected devices, in order for the TV to pass DD 5.1 you will need a service remote. In the EZ Adjust menu go to tool option 7 and change the EDID setting from PCM to AC3. TV will reboot and you will have full 5.1 pass through.

In newer tv models or old tv models with updated firmware, service menus like EZ_ADJUST may no longer be accessible through LAN. However, a suitable infrared remote control may still work. I have not tried it.

[mrchnk]

can confirm that custom ir-control works for EZ_ADJUST and IN_START with my LG 47LM640T (firmware 04.62.10). i have made ir-control using just 2 red diodes and send command using headphone jack and specific audio files

[zer0ring]

Can confirm access to EZ_ADJUST menu on 42LA6230 running software version 04.28.13 SDK Version 03.03 using Logitech Harmony One remote in following manner:

1. Install MyHarmony software for Logitech Harmony One
2. Add your Logitech Remote
3. Add a device from manufacturer LG and model 47LE5300-UC*
4. Choose Buttons and select LG 47LE5300-UC* in the select box and click Go
5. Drag EZ-ADJ from Commands menu on right to an unassigned button
6. Save & sync the configuration to your remote

EZ_ADJUST menu can now be accessed simply by pressing the assigned button.

*NB: EZ-ADJ command was not available for my model LG TV (42LA6230) but was for the model specified in the steps above. Python script works excellently for most other commands, just not EZ_ADJUST or IN_START menu invocation commands, I may likely use this in a RPi touch screen controller project, thanks for developing it.

Can confirm as of 2018 MyHarmony still offers EZ-ADJ for the model that zer0ring specifies.
