Had to return my FZ200 for another one

Had a problem that developed with the EVF in that it had vertical lines that were very annoying and just not right. I took it back to the store and luckily they did have another one in the store so got a new replacement. Hopefully this won't occur again. Wondering if anyone else has noticed a problem like this or know why it would happen? They were very thin vertical lines all across the EVF and in not particular pattern.

Mine has a very thin black line about dead center in the EVF running up from the bottom to about the halfway point. It is only really obvious when I shoot a solid bright colour and diopter is set right on sharpness wise. They look like dead pixels as they start to break down into individual black dots near the center of the EVF.

But I will take the camera back to the store to see what they say about it.

That is basically the way mine started and then got worse and worse. They hadn't seen this before at the store. When I took some photos this morning the EVF was basically covered with thin lines. Good luck with yours.

Took mine back to the store yesterday, no hassels they replaced it immediately with a new one that was good so far. Guess we'll see if this is a problem that develops vs one that is immediately obvious.
