Ok i just got my new tv the other day, i have messed with the brightness and other settings to where i want them. I have ALS turned off, DNR on auto, color temp on medium. But for some reason, the tv becomes lighter and darker while im watching tv and dvd's. Its mostly with darker colors its adjusting. This is really anoying and to tell you the truth it looks horrible when it adjusts from darker to brighter. And it doesnt even stay lighter that long it will change and then change back real quick. I though thats what the ALS was for but that feature is off. Any ideas?
