my motorola W490 phone screen keeps going white.?

[babii_gurl_x91]

About a month ago (if that), I woke up one morning and my phone was being really slow. (The phone is a Motorola W490) After awhile it froze completely. I took out the battery and put it back in but everytime I would close my phone the screen would either be white, black or be white with red lines on it. I can't recall having it near water and the water damage sticker is not red. I finally figured out that if I leave my phone open and never close it, it will not freeze. However sometimes I would forget & close it. The only way that it will work again if I do that is to take the battery out, put the charger in, my screen will light up & then I can put the battery in and it will work fine (unless it gets closed again) Any ideas on what I can do? And the phone is already over 2 years old and this is the 6th phone I've gone through so I'm not allowed to get a new one right now. Please help!
