I've modified existing generic LG lcd TV template with neede Ruby codes, but I have yet to talk to developers how to enter them in LMCE - so it will probably not be available soon...
Basically I based my work on this one :http://wiki.linuxmce.org/index.php/LG_42LB5D
I followed the instructions in the link and can not get it to work. I know my serial port works becasue I used to use it for a CM11A X10 controller. I have a null modem cable between my Hybrid Core and LG 37RZ55. I have tried sending test signals to it but with no response.
