Welcome to the forum.
It sounds like you have the unit in shop mode. To fix this, you have to do one of these two things:
1. Hold down the menu button on the television (not the remote) for 10 seconds. The screen might flicker or display "Dymanic", and if that's the case, you're where you want to be. (If it says Shop Mode, then you've put it in shop mode). Shop Mode is toggled on and off this way.
2. Same as #1, but push the volume up button once, release, and then hold down the menu button for about 10 seconds.
Keep me posted!
mMy mode setting always returns to dynamic from what ever setting I try to keep on it (ie movie) also I have to change this setting every time I tun the set on. I hate the Dynamic setting, the only way it will stay current while the t.v. stays running is to use the "E-Mode".
What am I missing here?
