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.

Please mention how many times standby light blinks on your KP-57WS520
There would be bit long pause between blinks so count the blinks and let me know to help you.

SOURCE: I have a sony KP-57WV600
Let me know when TV warms up does it go to standby?
If yes, standby light would be blinking, let me know how many times it blinks?
And if TV does not go to standby mode, does picture remain with red tone?

I have an RCA big screen older model television/I started with the same problem then the tv will no longer come on. Blinks 3 times and makes a fuzzing noise then does not come on.
