Possibly buying a 65" VT50 Floor model...any issues?

I want to replace a couple of TV's this year. i had planned on the Panasonic 65" VT50 then the ZT60/VT60 was released. Anyway, I need to replace one now. I saw a "floor model" at a great price (I know the owner of the store). The TV has just been on the floor for about 2 weeks and is the last one they have. I tried to get a new one but Panasonic Canada has no more available, sold out and now discontinued. Are there any issues to be concerned about purchasing the floor model? Anything to check for? This will be for upstairs family room. I do plan on the ZT60/Samsung whichever i feel I is best for my HT room when they are released in May.

THX.

Thanks for the suggestion. What slides do you recommend and where can I get them? Does the buzzing come from the front of the panel or rear of the panel?

THANKS!!

So I had the sales guy check the hours on the panel. It came up as 2000HRS! Certainly not a 2 week old "demo" panel. Haven't talked to my buddy that owns the store yet, Story I got from the sales guy was there were two TV's that were on display and they must have sold the other that was 2 weeks old. Do I believe that?...No. Small custom shop i don't think would put 2 65" VT50's on the floor at the same time.. I am disappointed, but happy I found out. Thanks to all the great info here and help from members. I will post back after i talk to the owner.

Yes I will still check the panel out. . It is a 30% discount or $1.250.00 off of Canadian MSRP. I think still is a good deal.

Ok So here is the update on the VT50. I went to the store and the first thing the sales guy did was apologize for the mistake on the panel age. He explained what had happened and the explanation made a lot more sense and he was sincere. The owner called me and also told me what had happened. Anyway....I ran the slide as instructed:

1) There was a very slight buzz on the "white" slide that I could hear up close 1-2 feet away if I was close to the side of the set. Straight on I couldn't really hear it. backing up to 6 ft I really heard nothing. Buzz was lower on the color slides I could not hear from 3 feet away in front.
2) There was some definite "burn in" down in the right hand corner on the white colored slides. It said Dolby True HD. When I switched to the grayer slide it was still there but very faded. Very very slight on yellow slide and none on the darker blue and greens and I could not detect any burn in on black.
3) The sales guy told me that he was not sure how long the demo disc was running on this particular set. He said it may go away and there was a "wipe" function that may help, but could not guaranty that the burn in would disappear. He said that the test DVD with the Dolby True HD logo label was fairly new to them and doesn't think it was used for very long. I could not detect the burn in during movie playback unless I really was looking and only very slightly on certain scenes if I really paid attention, none the less it is there..
4) the picture looked very good otherwise.
4) The slide colors were uniform, No lines or strip showed up on the right side.
5) all in all the set looked good except for the burn in logo which because i know it is there I will always be looking for.

Do you think the burn in logo will fade or go away? Is there anything that can be done to eliminate this?

The other curve ball that was thrown at me was I looked at a Samsung ES8000 LED. The picture was bright and the colors were so vivid and the black looked pretty damn black. I am not sure why people say that LED black are not good..I though the blacks were very good on the Samsung. However, there was a huge difference between the 6000 and 7000 series... those blacks ,looked dark gray and bleeding was evident on the 7000 and 6000 but not on the 8000..Never been an LCD fan, but the Samsung looked real nice. We kept on switching back and forth with the same source material and they both looked good (VT & Es8000). I did notice some motion blur with the LED. It got me thinking now VT50 or ES8000. If the burn in issue can be dealt with I think I would go for the plasma and VT50. I know that both sets had no calibration so hard to compare settings. I can get the VT50 at a good price. The LED I can get about 15% discount on the Samsung, but it will still cost more than the VT by about 200 bucks. any thoughts? THX

Thanks Yukon Trooper. I suspect it may be IR and not burn in as well. I asked the owner to run a day of regular content with no logo or black bars. If he agrees, I will check again after that day.

Burn in after 2 days? not just IR? was the TV on vivid mode or something?

So the update is...they sold the demo to someone else. I guess I was too much of a PIA. No worries I was able to find a brand new one. I think it is the last one in Canada since Panasonic Canada is sold out and I called 15 dealers within 60 miles. I got a tip on a wholesaler that may have one left. i called and they had 1. Bought it and got a 20% discount off MSRP saved $850. Delivering on Thursday. Thanks to everyone on this forum that took the time to help and advise.

MSRP in Canada is $4199 I got is for $3,350.00. I got then to through in a $200.00 12ft Monster HDMI cable ( I know Monster is way overprices...but it was free)

it was a wholesaler here in Canada.
