I have an old Zenith projection, 50",, Sad thing is, the picture is fine,, No sound on half the channels and every week I lose one or two more. I've looked, called, till blue in the face and cannot find a repair outfit that can fix or even simply look at this.. I figure another month and there will be no sound regardless of channel selection. So, I started reading a little bit, usually on BB/CC and box store pages. What type TV do you need? None mentioned replacing bulbs. Of course they won', there wouldn't be any sold. The plasma I know is out,,, The room we use is avg I guess at 25 X 20 in size, so 50 -55 inch screen is ideal,... An LCD would work with less problems than DLP? SO far I like the Sony wega 1080p sxrd whatever this is,,..
