object not rendered correctly when i take camera away from object in unity vuforia

I am rendering TV object on image target. it is working prefect in webcamera in pc. but then i compiled and installed in my android phone.

it is rendering fine when camera is too much near to target but i take it far, all texture become bright yellow type.

All material are in asset folder and most shaders used are "Standard"

Screenshot : 1. when camera is near to target

Screenshots 2 : when camera is far
