Hi there, I purchased a 49 in. Akai rear projection HDTV about a week ago and am still trying to learn how to adjust everything. I have 2 problems was hoping someone here would know what I should try to fix the problems or do I need to return it? First problem.... I am able to adjust everything except the Brightness, it is set on -64 and will not scroll either way, up or down. All the other ones will adjust but this one. Second problem is a biggie.....The whole picture is now centered on the t.v. There is a block down the right side of the screen that has no picture and you can tell that the picture is off-centered. Is there anything I can try to adjust to fix this or did I just get a bad t.v.? Thanks for any info you can give me, Kim
