Hi Guys
Your problem here has to do with the amount of aging that happens to the three colour tubes - red, green and blue.
Blue actually ages slower than red and green. What actually happens is the green tube deteriorates and due to green being the predominant colour for brightness causes the blue tube`s flyback lines to appear - especially when switching between inputs or when the video is blanked.
No replacing the blue tube will not solve your problem as the tube is actually the best one of the three.
As someone mentioned there is a way to adjust this by removing the speaker grill assembly in front of the set. Doing the service mode adjustment with the remote is not the right way to solve the problem - you would be adjusting the colour gain and off-set values and would seriously be compromising the white balance of the set.
On the left hand side behind the speaker cover you will see a black square block with six adjustment points. Look for the one marked SCR BLUE, Switch the set to a unused input so the blue lines become visible. Now adjust the BLUE point counter clockwise until the lines disappear. A small adjustment should do it, Switch back to a picture and make sure the whites are still white.
This should sort your problem. I would however suggest asking a Sony service centre to do this for you. This is a dangerous thing to do as you will be working close to the 35Kv supply the the anodes of the three tubes.
I hope this answers your question.
Goo luck.

When your tv shuts down after too much blue screen, how does its standby light flashes?
There would pause in flashes of this light, so count it and let me know to help you out.

hello High voltage
shutdown. The high voltage has exceeded 33k and the unit goes
immediately into safety shutdown. Check power supply regulation and
horizontal circuits.
