I live in my new motor home full time. I have an HDMI matrix switch to connect my Dish receivers and computer to all of the TVs using HD Base T. The motor home came with LG TVs and an LG Blu Ray home theater that powers the speakers built into the living room ceiling. The living room TV is a model 55LH5750. The home theater is a BH6730S. The TV is connected to the Blu Ray home theater by both an HDMI cable that I added, and an optical cable. Both are about 30 feet long.
According to the manual for the TV, it is supposed to control the home theater using ARC and CEC.The problem is that it rarely works properly and is unpredictable as to what it will do. When I turn on the TV, here are some of the things that can happen:
1. The home theater turns on and the TV sound comes through it and can be controlled by the TV. This is what is supposed to happen and it seldom works that way.
2. The home theater turns on and the TV sound comes through it and CANNOT be controlled by the TV.
3. The home theater DOES NOT turn on and the TV sound comes through the built-in speakers.
4. The home theater DOES NOT turn on and the TV sound doesn't come out at all because the TV is sending the sound to the home theater which is off.
When one of the undesired behaviors occurs, I will attempt to turn on the home theater manually. when I do, one of the following occurs:
1. The sound automatically gets redirected to the home theater and the I can control it using the TV remote. Like number 1 about, this is what is supposed to happen, but seldom does.
2. The home theater comes on, switches to the optical input and the TV sound comes out of it, but I CANNOT control it using the TV remote, but I can control it using the home theater remote.
3. The home theater comes on, goes to its home menu and automatically switches the input of the TV to the HDMI connection to the home theater.
4. The home theater comes on, but the TV doesn't switch the sound from the built-in speakers to the home theater. I can switch them in the TV setup menu.
Two other LG TVs have LG soundbars connected with optical cables. The TVs and soundbars interact so that when I turn on a TV, the attached soundbar automatically comes on. I control the soundbar volume through the TV remote. This happens without fail every time I use them. The TVs control the soundbars using a feature called 'LG Sound Sync (optical)'. This feature doesn't work with the home theater.
So...Here's my question. Is there a 5.1 amplifier that would use the sound sync feature (I don't know if this is an industry standard with a fancy LG name) that I could use instead of the home theater to control the speakers that are built into the ceiling of the motor home? Barring that, can anyone suggest a way to make the connection between the TV and home theater reliable?
