i don't think there are any crt tvs that are 42" in size because how big and heavy it is. it might not fit through the door with sizes that big or bigger than that.
unless its a rptv (rear projection tv) then it should be able too. sony did makes 40" crt tv maybe like 20+ years ago though. i think your panasonic tv is probably 36" as its biggest. nice to know it has component video input. is it one in component video input or does it have 2 component video inputs if you don't mind me asking?
