If the browser is defective and resets do not clear it up, you have a good reason to return it as DOA (defective on arrival.)
We recently purchased a Samsung 55" 6500 smart tv. We love it, great picture and other features. My problem is with the browser. Now I know it isn't a PC and I don't expect it to act like my PC just to be clear. The tv browser only comes up with the colors reversed. All web pages have a black background with white or yellow lettering. What makes it truly unusable is that the pictures on all web pages come up looking like a film negative. Remember film? I have called Samsung support and let the person access my tv by giving him or her the code to do that and they were unable to fix it. I have gone through all the screen settings but cannot get the browser to change. Am I missing something or do I need to demand an exchange on this tv? We bought the tv at Best Buy and purchased their five year warranty plan also.
