Hi, I've got a HS-50 which has been great for 2 years or so, but last night when watching a full screen film (16:9) that there is some light green banding along the bottom of the screen! Its only done 250hrs so not sure what this could be? It could have been there for some time has you can't see it when watching wide screen films (with black bars) which is most of the time. Anyone had this problem??? Cheers, Neil.
