Curved TV screens-don't get this either since movie theaters haven't used curved screens in years.Often TV makers try to duplicate what theaters do-same with the 3D.Wearing the goggles and watching 3D gives me the "HEEBY-JEEBIES"Some folks do get ill from it.Guess another reason it disappeared-but wait--when that next Hollywood 3D blockbuster comes out-folks will ant 3D sets again!Just wait!3D Seems to come and go.Children don't like wearing the glasses,either.Wonder if 3D is staill a thing in theaters.Don't see it promoted so much now.The 3D in theaters works better with digital projectors than analog film ones.With digital sometimes the person acting as "projectionist" leaves the 3D filter or wheel when showing a standard 2D movie-the viewers get a dim picture!At one time I used to fix TV's but gave up when sets no longer had replaceable parts like tubes and plug in circuit boards.You could work on those older machines-but later ones---forget it.Loved some of those "consoles" that there was nothing in there but the CRT,and a couple circuit boards and a speaker-most of what was in the pretty particleboard "wood" "cabinet" was air!My Hitachi CRT HD RPTV is still doing fine-from 2000! will replace the set when it dies.Give me more waiting for prices of new sets to go down more.
