Screen problem

[apollowings]

Hello,

Recently - and I have no idea how, my screen has done completely white.

Resetting the phone, connecting it to the PC and removing and re-inserting the sim card have all been fruitless.

Is this problem fixable or would it be an idea to send it back to the factory? 

Thank you one and all! xxx
