My iPhone 4 is having a yellowish C shaped tint on left side of the LCD.How can I fix it?

Its been a week that I'm seeing a yellowish tint on the left side of my iphone 4. Its C shaped i.e its not all over the screen.Is there a way to fix it. Please suggest some Do it yourself method as I do not have access to repair stores.

Sounds like hardware failure. No way to DIY fix. Take it to an Apple Store?

Actual LCD damage, most likely pressure-related, get a store fix or even new phone.
