Over the past couple of days I've noticed a pink hue/glow/shadow in the middle of my TV (model number: Ue55mu6120). The problem occurs on all sources/on the preinstalled applications. The television is only a couple of years old, but is out of warranty, meaning I'd like to know if it's fixable myself. Software or hardware related. It is a minor but increasingly annoying problem. Thanks to anyone who can help.
