Sony KP-57hw40

Hello, I am hoping that someone will be able to help me a little.  My tv plays and sometimes the tv blinks blue and then the screen will turn completely blue and then the tv will shut itself off.  This does not happen all the time, but i would like to fix this as the tv is very nice and works fine other than this issue. 

 

Also if anyone would have a service manual for this model that could email me a copy it would be greatly appreciated.  my email is [email protected]    thanks everyone.
