A:

The problem you are having is called convergence. Your TV has 3 picture tubes inside and the convergence circuit aligns the tubes to make a single image. This type of repair requires soldering skills and equipment. For a technician to come out and perform the repair would cost about $350 or more depending on any additional adjustments that are needed after repairing the circuit.

A:

I believe the line you are talking about is the retrace lines. They would be a zigzag pattern across the screen. The blue screen is being caused by the blue picture tube inside the set. The tube would need to be replaced, but there are no new tubes available for purchase.

Q:

my sony kp-57hw40 tv projection is only blinking red 9 times and wont turn on with no sound either...whats up???

A:

Televisions problems are much more complicated with the models today and few attempt self repair. The number of blinks is usually an error code. You may find information on this in the owner's manual. I located the manual and attached to the link below. Hope this helps while you wait for the expert.

The 9 blink error you are getting is typically and audio error. It could be anything in the in the audio circuitry causing the issue. A tech would need to make some internal checks to be able to tell what part of the circuitry is causing the problem.
