Fuzzy writings on high def images

Hi !

i've got an Xperia Z ( C6603 model ) everything was fine until some strange problems began :

-in some menus everything works perfectly without having problems infortunetly when reading email or big paragraphs the words are simply fuzzy , i've tried the restauration with Sony's tool but seems that's not a hardware problem

- also now i can't take pictures,specially when i take pictures the screen is as fuzzy as ever ..when i zoom in the trouble is less important

but the pictures themselves after being copied are simply clean

Wish you can help me fix this problem and give me your point of view

thanks ^^
