Hi guys So I just replaced my lightning damaged Sony with the LG 55UK6950PLB. Love the TV so far but was wondering if I am missing something with regards to DTS/AC3. I have the TV connected up to my (slightly ageing) Denon AVR1906 receiver which is DTS and Dolby Digital capable, using an optical cable from the back of the TV and into the receiver. I've done checks with my Xbox to make sure the receiver is configured correctly (the receiver displays "Dolby Digital" when connected through xbox optical) Two problems that I have. When using the integral Freesat tuner in the TV, none of the channels seems to output in anything other than stereo. My receiver only ever shows its "NEO 6:C" mode, which I believe is it's attempt to interpret a 2 channel input. I get the same using the integrated DNLA browser in webOS. DNLA server is Plex running on an iMac and connected into the TV with ethernet cable. I've tried numerous sound settings in the standard menu and even changed the EDID type in the service menu on the telly but that makes no difference either. Has anyone got any ideas on what i need to do, if anything, to get this TV to output at least a dolby digital signal from the optical out on the back. Thanks Mark EDIT : I found the following on another forum, I hadnt done the final step. Is that safe to do? "If you can access the service menu go to option 7 and change it from pcm to DTS. Then go to edid d/l and press start. "
