I have an LG 55LH40 connected to a hybrid which I'm hoping to get working effectively with LinuxMCE.
1. Ensure that your LG TV has the same commands as device template 2126. Check your manual. As far as I can see (looking at recent LG manuals) most LGs share mostly the same RS232 commands.
My ignorance prevented me from effectively performing this request. After much looking around the LinuxMCE wiki I guessed that I had to basically jump down to the 3rd, 4th, and 5th entries in the list to confirm the commands. My manual and the commands are different as the 6th entry notes some of the necessary changes.
Why not just create a new device template based on the existing template rather than modifying the existing template? The LG 55LH40 has an additional HDMI port (#4). Should an entirely new device template be created? According to my manual, 18 TVs are controlled by the same commands.
2. Change the Plug and Play script on your MD in /usr/pluto/pnp/20_LG_TV.sh to point to device template 2126. It should look like this.
Does the hybrid use the same script? I updated the script and disconnected the serial connection and reconnected but the connection was not acted upon. I also tried using the TV portion of the Setup Wizard but it failed to detect the serial connection as well. I can send commands directly to the serial connection and I know it works because I can turn off the TV and then turn it back on again.
I will do everything necessary to get this to work because I bought this specific TV because of the RS232 interface. I also want to ensure that the next time I decide to reinstall from scratch that minimal configuration will be necessary and can all be done from the Setup Wizard.
