Has anyone else had this problem? While watching television, live or recorded, HD or SD, the picture will flicker with a darker cast, then back to normal a few times. Then it will get progressively darker, darker, darker, then gone. After a couple seconds comes back. I have had this off and on for past week, one time requiring a restart. I use component cables only in a direct connection to the television. Acts like when a cable is just barely making contact (have had it with PS2 plug before). Anyone else anything similar? I would REALLY rather not send this thing back. Oh and I am on the old software here in the Midwest.
