I've had my Z4 for a couple of years now and now I'm noticing several faint vertical lines. It almost looks like a screen door and is very annoying. Is this something that can be fixed easily or does the Z4 need to be serviced?
Go into the Setting menu and click the Panel adjustment option on page 3. It sounds like you're developing vertical banding, and if that is what is happening, you can eliminate it there.
