All models
TV volume down & OK on remote only does a basic IC self check. It does NOT Reset the TV.
It does not clear channel programmed settings, picture settings, channel labels, LOCK mode settings, or password.
Using this method, it shows the unit firmware version (Peaks 1.050 and GenX 1.00) and it checks IC communications ONLY.
This is more useful to identify the firmware version without having to decode the info in the setup menu About/Version screen.
NOTE: This procedure does
not reset the TV
