Yellow streaks on white screen sony lcd

[sfris]

3 vertical yellow streaks/blotches most noticeable on a white background, IE hockey game. Sony lcd kdl46z4100 2 years old. Could this be a screen surface issue, or is this more likely a bad screen. How best to diagnose.

It's very possible you have a screen delamination. Time to call the warranty folks.
