There were some that I know work for different menus by I really only gleaned these from the main menu screen. I poked around changing just the command byte and found some more updated codes that were not included in the spreadsheet (SMART TV functions and such). The spreadsheet is a little more straight forward (and a bit robust). The PDF you attached is inline with the attached spreadsheet. I've seen 2 different protocol types for Samsung TVs in my search. I used this spreadsheet to program a Samsung UN40H5203 I bought a month ago. I've found this protocol posted here by the guy with the One Piece avatar (Luffy), sorry that I don't remember your name :P. But I'm curious if they also hold true for the LE40A656 series and the LE32A330 series. Looks like the above HDMI based system will probably work with the TVs you have as long as the TV signal is being provided by a PC via HDMI, not sure how the app would handle multiple TVs but it could lead to a very impressive solution giving you large amounts of centralized control over existing HDMI distribution.Been trying to find them, have found some. If they all take input via HDMI then there may be a way to control them via that witha program like this Probably not cheap but a decent looking cnetral control solution. With the above TVs you are right in thinking that IR is the only way, cheaply you could wire up one of these in each room with the switch wired back to a spare network port or something.Ī better solution could be using one of these IRTrans Infrared Control System which would allow you to send different commands to the TVs.
Looks like those TVs are extremely limited in their connectivity options, some models have serial ports that give you full control of them which is the best solution.
