What you do with this information is your own responsibility. If you brick your TV trying this, it's not my fault. You should probably have some electronics experience if you want to attempt this.
This is going to involve opening your TV and attaching wires to the pins of an integrated circuit. If you're not comfortable with that, this is not for you.
This document is a work in progress.
LG TVs since at least the era of NetCast and "Global Platform" (webOS predecessors) have had the notion of a debug level, generally called "debugstatus". There are three modes: DEBUG
, EVENT
, and RELEASE
. TVs normally operate in RELEASE
mode. DEBUG
mode enables a variety of logging and other debugging features in webOS, including access to the bootloader console and debug menus via serial. EVENT
is similar to DEBUG
, although it may not enable as much logging and has other relatively minor differences.
