Rainbow spot....

[EDTIVA]

I have 3 Nino's 210, 300, 500... and all of them seem to get this rainbow spot on the screen while it is on or off... It appears like it is moisture under there and you can move it around. ANyone know what this is, Velo guys do you know? I am tempted to take one apart, but just dont know if I can get down to the level where its at... it appears to be between the protective original plastic and the actual LCD. Any thoughts?

I'm a Velo guy <g> but don't remember ever seeing a rainbow on one or hearing anyone else say they did. Does the Nino have a color screen? The Velo, both models, is black & white only.
