I need some Pro advice here. I bought a Toshiba 51HX83 a few weeks ago, got it delivered only to find it possibly defective. Future Shop claims they can’t find another (factory sealed) unit and don’t know how long it will take to get one. Now they have, of course, offered my money back which is nice. Or I can take delivery of a Hitachi 51F500, which dollar wise, is a cheaper unit (I’ve read all the comparisons here in this forum). I’m not all that convinced I’m getting the best possible pic from the unit. I have a non-HD satellite receiver and have noticed when flipping between channels that there is a large (faint) white ring on the all black screen. The ring is the full height of the display and pretty close to being dead center horizontally. Another image problem is color depth. By that I mean; no blending of color shades, there is a pixilated boarder on large background images that have varying lighting applied to it (does that make any sense?) It’s kind of like setting your computer vid-card to display only in 256 colors. Does this sound like it can be remedied with professional calibration? Who services S-W Ontario? I think the last thing I want is a FShop sales clerk muckin’ around with this set. How does one go about finding a Certified ISF Technician in their area? And how about some more info regarding these AVIA disks I seen in a few posts? Thanks for any & all help.
