Do a google groups search for Sony blanking video, sony AKB, Sony blinking video, etc.

Odds are very high that the picture tube is simply below specification and the AKB circuit can no longer compensate, hence the blank or blinking video at turn on. Very common failure on older Sony sets. Proper fix is a new picture tube, not cost effective and many times no longer available.

If a slight increase in the G2 voltage to the tube temporarily corrects the problem, it is the tube. Time to start shopping for a new tv set.

Very common Sony problem, not odd at all.

Very common indication of a failing CTR. Not cost effective to fix. Sometimes temporarily fixable by increasing the CRT screen voltage. Maybe it's time to consider. New set.
