I just took delivery of a Toshiba 50H82. I calibrated it with Avia and to say I'm disappointed in the picture would be an understatement. Cable looks pretty grainy, which I expected. Directv looks equally as bad. Lots of artifacts and dark colors just don't seem right. Last night I played around with a few DVD's and these all looked equally as bad. Brighter scenes looked pretty good, but anything with lots of dark stuff was awful. Black and near black colors appear to be full of artifacts and sometimes have other colors such as red or green mixed in with them. I'm beginning to wonder if my expectations were too high, I have a defective TV or maybe I just need to call in the calibration experts. Can anyone recommend an ISF tech in the south east Michigan area? Any other Toshiba owners have some advice to help correct my problems. Thanks.
