Why off? IT is the RFI reflector<:-))

I have the Samsung 40" which was all we had room for in the 
entertainment center.
The TV antennas are mounted on the tower at roughly 90-95 feet. The only 
interference was on channel 12 when operating on 2-meters with the 
stacked pair pointed in the same direction as the top 100" long UHF 
antenna with an antenna mounted preamp.  Even then the RFI was not bad, 
but that was on analog.  So far with digital reception, same antennas 
and same power there is no indication of interference to the TV set.  I 
hear nothing on the ham bands up through 440.

I stay as far away as possible from Sony with their attitude toward 
customers.
Also I much prefer the new LCDs over plasma as viewing angle, 
brightness, and contrast are no longer problems in the higher end sets.  
(Try before you buy).
