LG webOS Smart TV
LG Smart TVs usually run the webOS operating system. If it is older, they may run Android (Google TV), or SmartView. ZENA forensics has made an analysis on a 55SK8000PUA tv.

Partition structure
Four EXT4 partitions can be found.
7-zip revealed a SquashFS at the beginning of the image.
The Squashfs has a Linux-style folder schema and seems to contain the WebOS files.
I decided then to run "binwalk" on the image: the tool found 6 SquashFS file systems.
Overall I found six SquashFS, extracted by binwalk and four EXT4 partitions, extracted by MobileRevelator and TestDisk: Partition 0 (/mnt/lg/uhdcp), Partition 1 (/var/db), Partition 2 (/mnt/lg/cmn_data) and Partition 3(/media).
SquashFS files
The six SquashFS files contain the stock LG WebOS. The "/etc/issue" file contains the operating system version. In the dataset it contains "webOS TV 3.5.0".
Partition 0 (/mnt/lg/uhdcp) and Partition 1 (/var/db)
Partition 0 (/mnt/lg/uhdcp) and Partition 1 (/var/db) don't seem containing useful data from a forensics perspective.
Partition 2 (/mnt/lg/cmn_data)
Partition 2 (/mnt/lg/cmn_data) seems containing the most interesting files from a forensics perspective.
