I bought the KV-28LS60 after reading a review saying how good the set was. When installed along with my Sky digibox and Panasonic video, I noticed that when the Sky TV guide was on, the dark blue bar at the bottom of the screen curved upwards in the middle. I then checked terrestial teletext (in case it was due to the digibox) and found the same problem. It can also be seen if there is a straight line showing in a TV programme/film. It went back to the vendor for their engineer to look at - no fault found. Sony said it could be down to radiators/electrical goods etc near the set, but the only things near it are in the stand as said above. I have spoken to a friend who is a registered Sony engineer who said that the set is within spec, but admitted that he could see the problem. I would appreciate any help given as I think the set is otherwise great, if only for this problem.
