LG TV discrete tuner commands
I'm trying to control an older model of LG TV ( 55" ) and the only available way is through IR ( no free RS232 ports in my
The customer has tuned some DTV channels as well some ATV ( for cameras ) and Radio ones.
What I need is to send discrete commands for any band ( DTV/ATV/Radio) but I cannot find any of them.
I'm sending the discrete ANTENNA command, which is working as expected when the TV is on another input like HDMI1, AV2, etc. - it gets the TV out of the external input - but switches it on the last selected tuner source ( DTV/ATV/Radio).
In case the TV has already been switched on a tuner source, the ANTENNA command switches the TV to DTV->ATV->Radio->DTV->ATV->Radio->DTV->ATV->Radio and so on....
I do know that there are discrete RS232 commands for all of the tuner sources. Has anyone of you found the corresponding discrete infrared ones for LG TV's?
