The problem is that somone who doesn't understand this problem should
accidentally press one of those buttons by mistake. Also it's annoying when
it does happen.

Luckily it does not appear that the remote actually lets you change any of
the settings once you're in Service Mode. The only way to change a setting
is from the buttons on the TV itself. I guess it would not hurt to write
down all the settings just to be on the safe side.

I didn't tell the wife though since she is one of these
folks
who thinks anything beyond an ON/OFF button and a way to change
channels/volume
is a waste of time so the service settings would surely throw her for a
loop.
