Texas Cx Cas Display Pixel problem

Hello everyone.
My Texas Cx Cas calculator has a problem with your display.
Your image has whiteness and pixelated, make it impossible to see a calculator informations on your display.
Attached has some imagens of the problem.
Someone knows how to fix it?
If i put on Texas Student Software the calculator works no problems, because it see the virtual display on computer, working no problem.
The problem looks only on display screen.
