Same problem. Overall green hue to the otherwise fine picture.

If I swap connectors j7202 an j7302 on "A" board and the problem changed to the Blue tube. So I suspect the green gun circuitry is overdriving the gun and causing the tv to shutdown.

symptom is when tv is powered on the screen goes bright green and the tv shuts off then flashes red led 6 times. This repeats each time you attempt to turn on tv

I solved the "green screen" problem by making adjustments with the focus block. These adjustments are accessible by removing the front panels.

Green hue on KP-43Ht20 Sony rear projection tv

Behind the front cover you will see a little plastic box with six phillips headed dials. They only move 180 degrees. The three on the bottom control color richness and the three above them control focus. Turn all three of the bottom ones to the left while the TV is on, then gradually turn them to the right until you get the color you want. NOTE if any one of the three bottom dials are too far up the TV will shut down and will continue to turn off after about 10 seconds after start up until the offending dial is turned back a little.

5 times blinks is error code for No Good White Balance and you said that picture is very green.
As you know TV is approx 7 years old so it needs RGB gain adjustments.
If you are TV tech person or know about TV repair, let me know to guide you further. Or contact local TV repair shop to fix it.
