Hi, I just started seeing this strange behavior with my EM-5. I'm seeing purple horizontal lines on the LCD and EVF. It's particularly acute when it's dark, or when I have the lens cap on. The pictures taken also seems to have some horizontal banding. Is this a firmware/software issue or is my sensor hosed? Has anyone experienced this before? I've had the EM-5 for over a year, so it's out of warranty. So, I want to try to see if it's a real problem before sending it in. Thanks.
