This could be a problem in the vertical sweep circuit, as when the vertical circuit fails, The video or screen will blank out so the picture tubes do not get damaged. In this chassis, I have seen the convergence IC's cause this, or the capacitor in the sweep power supply that feeds the voltage to the vertical IC has failed and blew out the vertical output IC. If you have no solid state repair experience, play it safe and call in a trained tech to assist you in this repair. Good Luck.

Check the info from this website to see if you are able to fix your TV. You should turn the blue screen control down slightly counterclockwise. If that did not work, then more likely you have a video amplifier IC defective or a blue CRT.
