Hi. Earlier this year, my father gave me an old Mitsubishi 46" widescreen HDTV (I believe the model number is either WT-46805 or WT-46807...the TV's manufacturing date was sometime in 2001). Recently, the TV has been distorting the picture upon power-up so the picture looks "concave"...that is, the top and the bottom of the picture are bent inward. This also creates some ghosting effects. Usually it stops after a few minutes, but sometimes I have to turn the TV off and then on again to get it to display properly. I also have it hooked up to Dish Network (regular package, not HD). Does anyone have any idea what this could be, and if so, can you please explain it in as non-technical a way as possible (I'm not very good with in-depth tech stuff)? It seems weird to me that a TV that's only 4 years old would be having problems already. Thank you for any help you can provide.
