I have just bought a LG BH9540TW Home Theatre that I want to connect to my LG 42ls3450 TV but the TV does not have an Optical Out port. What's the best way around this? Thanks for any help.
Since your TV doesn't have any audio outputs at all you can't get sound out of it. If you use a set top box you can connect directly to it. You have both optical and analog audio inputs on the LG HTiB.
