Re:
Witch part of the screen you loose?if is the bottom or the top it could be a problem in the vertical IC circuit if is the left side or the right side is a problem on the horizontal deflection circuit(very rare),try taping on the set when it does it and see if the pix reacts ,if it does one way or the other you have loose conections and some resoldering need to be done.If you are familiar with tv circuitry you will have no problem.If you are not be safe and call for help.
