I have the tint on my 500m, but I remember seeing it a longg time ago. Honestly, it's a non-issue if you watch the TV with *any* amount of light in the room. The room basically has to be pitch black for me to see any of the redness.
It's difficult to even use the word "tint" because that would imply the red color adulterates the whole display. In reality, the red only shows up on black in a completely dark room, and even then, it's subtle.
