My Samsung M550 screen has turned white..how can I fix?

M550 samsung screen has turned white - cant fix - no repair places nearby and cant afford new phone. Is there any temporary FIY solutions I can do, until I can find a repair place. Can still make outgoing and receive incoming calls. This has been a great little phone. Unlike some others, ive had no problems until now. Im in a rural area. So im hoping phone doesnt stop working completely. To anyone that can help, thanks.
