This blog is dedicated to all those who use Display Express systems to control TVs. Here, we’ll summarize the “controllability” status of popular makes of TVs, and we will update new facts and gotchas as we discover them. For example, a few sets need to be set in in a special mode, or an energy-saving mode needs to be turned off for RS-232 commands to operate. You’ll notice there is some flux in control and features in the industry, so feel free to contact CR Support when you’re planning an install – we are happy to research makes and models.
LG TVs
G control code is one of the best, our current code can lock and unlock TVs, as well as select inputs. If you select an input, send a TV input command to return to the current channel – sending channel command won’t switch to the tuner automatically.
LG sets will lose the lock state when power is lost. Our ICC1-232 controllers will automatically restore the lock and power state when power is restored to the controller and TV. If the TV was off when power was lost, it will keep the TV off until it receives a power on command, and will restore the locked state.
LG Consumer TVs Have RS-232 Control Again!
New LG consumer TVs have brought back the RS-232 port that has been missing for a few years. Sets with the port will show an RS-232 mini-jack when you click Tech Specs on the product page. The new port is found primarily on new Web OS TV in sizes 32” and up. Models with the port include:
UH 610 and 616
UH 6030 – 9500
LH 700, 570A
LF 595B
LF 5300 – 6350
LH 570A, 700
LH 5700, 5730, 5750
Note that the port is non-standard; the TX and RX connections are reversed from our standard CC-COM 3.5 – when you order the CC-COM 3.5 for these models, we will include an adapter that fixes the issue. If you are making your own, the stereo plug need to be wired as follows:
Tip – TX
Ring – RX
Sleeve – GND
