Subscribe
I just purchased my new TV, an Akai 27" flat screen and I really have been pleased with it. I do have one problem with my picture quality, the lower the channel number is the worst the picture quality. Example channel 140 looks great but channel 1 is not that good. any suggestions, tips, help. Im running my antenna through my cable box. Is their something I can buy for improved pictured. Also my fine tuning didnt help that much.
Welcome, gmal2003! The DVD Talk "Main" forum is for discussion of DVD releases and related topics. I'm moving your thread to the Hardware Forum, where it will be more at home.
And I'm closing this thread as it appears you are posting the same thing in multiple forums. That's a no-no around here.
