getting DIAGONAL lines in your lcd?

Why am I getting diagonal lines in my LCD that can only be seen when holding the LCD at an angel?

The lines that you see on the LCD after refurbishing the screens comes after the last step of putting it in the autoclave. So basically what is causing it is the ​wire that you are using to separate the glass from the LCD is causing micro scratches in the LCD and when you put it in the autoclave it forces air into those micro grooves causing the polarizer to separate from the glass. The good news is if you just set that screen to the side for 24 to 48 hours and then retest it on your testers then 9 times out of 10 they will all be gone. So don't worry about the diagonal lines and just retest your screen the next day and you should be all good to go.
