White Screen on u740

I was recently using my u740 and just all of the sudden the screen turns white. It is like this in both horizontal and vertical modes. Although the front display still works. I have not dropped it or anything so i do not know why it would do this. Can someone help me please?

If it is a Verizon Wireless phone and you have bought it in the past year, it is covered under warrenty. When mine loads it will start with a white screen before it goes to my pic on the main page. Did you try setting the background on the main page, change the wallpaper and theme, if nothing works, like I said take it back if it is still under warrenty.

If Your screen shows a: white vertical line on a black screen or, a white horizontal line on a black screen:
Your TV vertical or, horizontal power transistor or, chip is getting too hot.
A vertical line indicates the horizontal circuit is at fault, a horizontal line indicates the vertical circuit is at fault.
To troubleshoot: Turn on your TV untill the line shows then: after about a minute, remove power (unplug) the TV, remove the TV back cover, carefully using your finger find the too hot transistor or, chip; or, use component coolant; spray the too hot component with a component cooler repower the TV, until the screen comes back to normal. To fix: apply white sylicone coolant cream to the back of the too hot transistor or, chip. or, if there is room, a small fan can be wired in to cool the part. Radioshack sells the cream and, also a "component cooler spray" that should find and, fix this problem, also; with power removed you can, if you feel it is safe; carefully (with only one hand) feel the part; it will be very hot! (it could burn your finger!) Do not touch anything else! (this will not hurt the tv; when the picture comes back on (the offending part has cooled) you have found the problem part.
