has anyone ever successfully send rs232 commands to there tv from an arduino? Ive seen all kinds of arduino rs232/serial stuff but nothing tv specific.
sorry what I meant was send commands from the arduino to the tv such as input selection or power on/off
AS RC said, you would probably have more luck controlling your TV with a Arduino by having it emulate the IR remote control commands. Or do you require some application where the Arduino must 'listen' to something the TV outputs?

well whats the purpose of the rs232 jack found on the back of most flat screens

Are you sure that is an rs232 jack, and not some digital video interface jack?

ya thats what it says on it. TVs with RS232 | AVForums

check this out, pg46 talks about it
No i do not have an lg but the manual for my does not give you such info, there is rs232 information all over the net what I am trying to figure out is if the arduino is capable of sending such commands and if someone has done it I would love to read about it.
ok thanks
its no secret its a TH-42PX80U I wasnt looking for a copy and paste solution, it seems like getting the commands is the easy part. I was just trying to figure out if the arduino is capable of communicating with a tv via rs232

Answer to the more general question is, yes, with the proper external hardware such as: SparkFun RS232 Shifter - SMD - PRT-00449 - SparkFun Electronics
