My sony tv KP-61XBR300 no turned on and blinks 4 times red light stand by.


This code means the vertical output circuit isn't working. If the set doesn't come on at all (no picture or sound), it's usually due to power supply problems. If you get sound but no picture, it's typically because of bad solder connections or parts failure in the vertical output circuit. My suggestion would be to have a professional servicer give you a repair estimate.
