Well, after 4 months of perfect operation, my Panny PT53WX42 has a major problem. All of a sudden, everything has a blue tint to it... it's happening across all inputs, so I know it's none of my source devices. It's somewhat noticiable in normal viewing and VERY noticeable when the screen is dark or black... screens that should be all black are basically blue. It's as if one of two things are happening -- either the blue gun is working at twice the intenseity, or the red gun is working at half the intensity. Obviously, it's still under warrantly and I've got a call into my local Ultimate Electonics service department and they are supposed to come and check it on Wednesday... has anyone else heard of this problem? Could this be an indication of bigger problems down the road? Should I insist on getting a replacement versus getting mine repaired? The guy on the phone said they might go in and try some adjustments, but I don't just want them making service menu adjustments for what seems like some sort of mechanical problem, do I? Oh and before anyone asks, I have NOT messed with any of the mechanical or service menu tweaks... so I know I didn't cause this problem myself! Any suggestions or thoughts would be appreciated.
