I just recieved and older panasonic 50" plasma display for free model # TH-50DHP3 I cannot find any info on it. Can anyone tell me anything about it? Also I think I am totally screwed it only has bnc inputs, Will they do 1080i. So is there anyway to hookup a high def cable box or blue ray to this tv? Should I just sell it and get something new? tv and picture are in great shape was just serviced by a panasonic dealer in MA. Thanks for any info its will be much appreciated!
