I've read various threads about the vertical lines problem on Panasonic TX-28PL1 TV's - unfortunately I read them AFTER I bought the TV ! The picture's great, however bright images and fast movements cause straight vertical lines to shift slightly to the right. This is most noticeable when watching the news (where they have a picture in picture) or a studio based programme, but hardly noticeable on other programmes or DVDs. Problem is very noticeable when displaying menu boxes, the right hand side of the menu in particular is not straight - it bows and blurs. When in 4:3 mode, I can actually see the black side bars wave and wobble up and down the screen. Also they are slightly curved at the top / bottom. What should I do?? 1. Reject the TV and request another ? The picture is great and I think I might stop noticing the problem + I'm worried that a replacement may be worse! 2. Request an engineer? Can the problem be resolved? Help and advice appreciated.
