LOL, no crap.
Accessing the Service Menu will only void the warranty if you mess something, just going in and peeking around will not void anything. Generally they are no default values from set to set, most times they are different IIRC so if you change them, they are changed. Settings in the service menu also have nothing to do with break in. It's not an egg, just turn it on and use it, you wont break it, but turning it on and off is a little overboard.
I have some questions regarding resetting the TV settings. Does doing the master reset in the setup menu clear any changes made in the service menu? Also can powering the unit on and off to check setting retention in the service menu do damage? I am worried because over the course of about 20 minutes I powered the unit on and off about 5-10 times trying to check if any changes were retained. Does accessing the service menu void the warranty and could someone please provide the default contrast values in the service menu for THX Cinema? Can settings in the service menu do damage to the unit if it is still in its break in period? Thanks again in advance, you guys are my best resource to learning the ins and outs of this unit. I am worried sick about damaging this TV and as of today I think it is outside of its exchange period. The TV only has 61 hours on it and has been powered on 49 times. Is this bad? Also could with that few of hours could a change to the contrast do damage? The contrast is the only variable i could have possibly edited, can this corrupt the firmware? Sorry about the sporadic nature of this post but I am incredibly stressed and worried as stated before and just need some feedback to put me at ease.
