I replaced the bulb a few days ago on my KDS-50A2000. Before resetting the bulb timer to 0, I went into the service menu to see how many hours I had gotten out of the old bulb. Unfortunately, as careful as I was to only press "2" to scroll through the settings, I accidentally pressed "3" a few times, changing some settings. However, I did NOT press the sequence to save the revised settings - I just turned off the set. Could someone please confirm that this did not mess up my settings? The only change I have noticed is that my black level is a little bluish, especially around the edges. However, this edge b leed might be just a result of the new, brighter bulb.
As a possible check of this, could someone point me to a listing of the default service menu settings for the KDS-xxA2000 sets? I'd like to check those settings vs. the ones that I might have changed. (I have changed a few settings per CNET recommendations, but only through the normal user menus.)
