Making some headway, but puzzled. Okay, I have video now, but don’t understand why. The base resistor of Q402 in circuit read low. So I had to remove it to test it. It broke installing back in the circuit. R414 a 51K resistor is now open because it’s broken in half. So I have video, but if I jumper in a new resistor my video goes away again. Any ideas Sony experts? Have to wonder if ABL circuit is shut off with the resistor being open in the circuit
