Quote:Have you tried getting an LG service remote control to access the EDID section in the service menu and change the setting from PCM to AC3? The procedure can be found by Googling LG and EDID,AC3 or in earlier posts for last years's models. I have a one year old LG 55LX9500 and it worked fo me.
Accessing the Service Menu
To access the Service Menu.
1) You must have either Service Remote.
p/n 105-201M or p/n MKJ39170828
2) Press “In-Start”
3) A Password screen appears.
4) Enter the Password.
Note: A Password is required to enter the
Service Menu. Enter; 0000
Note: If 0000 does not work use 0413.
Service Menu: Downloading EDID Data Pg 1 of 2
1) Press “ADJ” key, E Z Adjust (tool option 1)
. 2) Select menu,
Either “PCM EDID D/L” or AC3 EDID D/L
3) Highlight “Start” then press
4) When Writing appears downloading in
5) Downloading Complete
Note: When AC3 is downloaded, PCM will be N/G and when PCM is downloaded AC3 will be N/G.
This means that when AC3 is OK, AC3 audio is priority.
Before I did this, I contacted LG, who told me that a local LG rep would come to my home and do this free of charge. But I wanted to do it myself and am glad I did. It's great having 5.1 Dolby out of the sound system.
