Hi everyone. I'm having a frusterating experience with my LG 55LW5700. I've had it for a week now (purchased at cosco) and for the life of me can't get it to output in 5.1 digital surround to my Sony Stereo. Here's some background info...
- Using HDMI cable from my comcast cable box to TV
- Using HDMI cable from my XBOX 360 to TV
- using OPTICAL output cable to my SONY Receiver.
- TV speakers set to OFF (which greys out all audio adjustments for tv)
- If i use the optical cable directly from cable box (or xbox) to tv- I get 5.1 surround so something is happening during the input / output from the tv
This is the same setup I used when I purchased a Vizio 55" LCD 3D - and had full surround sound from comcast box and the xbox(which later returned to Costco because the terrible 3d mode).
I called LG's helpdesk and after the guy had me fiddle with a bunch of settings in the SETUP menu - he put me on hold and came back saying that the TV will ONLY output a 5.1 surround sound signal if I use a CO-AX cable from my comcast cable box to the TV and said my current HDMI cable is messing up the "direct connection" of audio and that it will only send a PCM signal. I can't wrap my head around this but basically he said my tv is covered under Warranty and a service technition needs to come out and will make an update to the tv so HDMI cables can be used - but I will risk having Lip-Sync problems from my comcast cable provider.
Has anyone ever heard of such a thing? Is there a firmware update that can fix this? I absolutely love the 3d imaging the LG has and I'm doing everything I can to resist the temptation of giving up and returning this for another brand of TV.
Please help - with specific instructions (or links) if this topic has been covered before. I spent 30 minutes browsing this website for the answer.
thanks -
Brian
