LG LHT854 Theater System Logo
Posted on Dec 20, 2008

Sound goes off

I have an LG LHT854 home theatre and a LG 42LG50 TV.
I purchased a Logitech Harmony 670 Remote. I have it programmed, but when the TV powers on, the Home Theatre also powers on, which it should do. However, the sounfd goes off after about 3 seconds. The sound will only stay on if I wait about 2 seconds after I power on the TV to power on the Home theatre.  Any suggestions? Thanks

You probably have too much power running to your power strip that you probably have your xbox, playstation, tv and home theatre system plugged into, try using seperate wall outlets for your tv and home theatre system

Setting up my Wii system using Harmony 670 Remote

Hi,

I just thought you should know the Harmony Remote is only able to control any device that uses infrared control. Unfortunately the Wii console uses Bluetooth technology which means the Harmony Remote would not be able to control it.

Hope this helps you!

Need a new LCD for Logitech Harmony 670 remote

Logitech does not sell replacement LCD screens for Harmony remotes.

I would suggest buying a broken remote from eBay or somewhere cheap. However, keep in mind that attempting to repair your remote will void the warranty.

Hope that answers your question.

Need program codes for harmony 670

Your Harmony remote does not use codes. In order to program the remote, you must download the Harmony software, which you can download at http://logitech.com/myharmony. Once you have the software installed, you will be prompted to create an account and complete the setup.
Hope that helps.

I just bought a Harmony 670 Advanced remote, but no instruction manual. How do i program it to my TV and DVD? please help!

I can help you with your Logitech Harmony 670 remote control.

The Logitech Harmony 670 remote control is programmed through the
Harmony Windows Setup Software.

Once installed, you will simply run the program and select the devices you would like to control from menus. This program finds the right codes for you and loads them into your remote control.

I hope that helps.
