Pioneer SD P5071-K has a dark picture, though, a good one.

My tv has a dark picture. Everything else seems to be fine. To view the set, I must position myself, just right, in a relatively dark room. The picture is still a straqin to view under these conditions. I've called the repairman, he states " well, it's gonna' be $189 for the service call, I'll give it a good cleanin', that'll add about $100 to the bill, after that we'll see how she looks. Ifin' she's still dark we'll try a few other things. So, it'll be $289 to start, that might just getter' done. But don't worry, Mister, I'll stay at it 'til she works or I gotta' go eat supper!". WHHAAAT? Well, could you please give me some advice. All else works well. Thanks in Advance! Jim
