I have a Paperboy that has always seemed to have the "jail bars" on its monitor, which has a 4900 chassis. I capped it a while back, and it really didn't do much. Recently, the flyback was changed. It has the same bars and also a strip of brighter color on the left side, which is not foldover.

Anyone have any ideas what to do to fix this?

Thanks.
