It's incredible and extremely concerning that they no longer have parts to fix these TV's. Even if they offer a full refund, what are you going to buy with that money? Nothing comes close to the VT60 that's currently on sale, except for the F8500, and that one is hard to find and not cheap and comes with its own set of issues.
My own 65VT60 (which is about 16 months old) acted weird last night. It was displaying a very faint, sightly flickering horizontal white line in the lower black letterbox bar while watching 2.35:1 movies. I would say ionly 2 or 3 pixels high. REALLY faint. It was intermittent and seemed to go away every time I switched from HDM 1 to TV/Cable. But then it would come back. Again, very faint (my wife could not even see it) but annoying and distracting since it ruined the "floating image" effect on a 2.35:1 movie. Those blacks are quite dark, as we know, so any variation in light output is immediately evident to the trained eye. I thought perhaps the disc was defective, or there was a fault in the encoding or transfer of the movie (the original "Casino Royale"... NOT the Daniel Craig film), since the line looked like time-code data or something you see in crappy local broadcasts from a no-name station, the type of data that used to be invisible due to overscan in the old sets. I switched from HD Size 1 to 2 and back, and it was still there, so it wasn't the disc. I then turned the TV off but still no luck (the line came back again, it would go away when switching inputs, and then come back). I finally turned my Oppo 103 off and on again, watched about 90 mins of other 2.35:1 blu rays afterwards, and the line SEEMS to have gone away. Perhaps it was an HDMI handshake issue (never happened before) or the Oppo just needed a re-boot... Not sure if the Oppo or the VT60 were to blame. Still, comments like the above REALLY concern me. I would be heart-broken if my VT60 needs repair and there's nothing that can be done about it. I even bought the 3-year warranty, but it seems that wouldn't help at all. I just hope that this thing lasts enough time for OLED to become affordable in a 65" size... Very, very upset about Panasonic not keeping enough parts in stock. I'm really sorry about your case, David. I hope you are able to work out a solution you are happy with. Please keep us posted if anything changes.
