LG LCD TV(LD35 Series) Remote Control
Few weeks’ back I have purchased new LG LCD TV (22LG350).This model got USB port and RS232 serial port. You can attach you storage device like USB pen drive or external hard disk to play pictures and music. But unfortunately there is no option to play movies from you storage device.
Technically, It should be possible to play movies(with movie player) as you play music with built in music player in LG TV. After going through several posts and forums like http://lgusb.wikispaces.com/ , I discovered that you need to just change one flag from 0 to 1 in some hidden menu known as EZ-Adjust menu. Information on Divx flag (in EZ-Adjust menu) can be found on lgusb web site.
There are several tips to reach at EZ-Adjust (Hidden menu) where some suggests to buy universal remotes, IR hack and firmware upgrade/downgrade. Since there is RS232 port available on LG TV and manual suggest that this is for serial communication with TV. Actually TV has operating system “saturn6” and you can communicate with OS via serial port.
So I thought to build Remote control for LCD TV running on my Laptop and communicate with TV via serial port (RS232). The source code for this application is attached here and setup for this application is here. If .net framework 4.0 is already installed on you system you may download executables only.
What else you will need to run this.
1.Cable (RS232);
2. USB to Serial Convertor (If your system doesn’t have COM port)
Before running this application you need to identify the com port on which your TV is connected. Run the application, select correct COM port and click on button “On” (Communication).
