Unhappy Stuck pixels on Xperia Ray

Okay, tried stock ROM coming from a custom ROM. And I still have these weird black lines on the screen. Is there a fix or I must go for a new phone or display?

And can anyone tell me where can I find a new display for Xperia Ray?

Device : Sexy Xperia Ray in red
ROM : Smooth Xperia Ultimate HD 5.0
Kernel : Superb Lupus Kernel
