Aside from the parts you mentioned check the vertical connection to the yoke (usually yellow and green wires), it may have a cracked solder joint or it could be burned. Also check the yoke for a broken vertical winding.
If the line is yellow with no other colors you may also have a bad color gun or drive transistor. If all color guns are working the line should be white.

Why are green horizontal lines are appearing, too much yellow colour and green light blinking red?


These horizontal lines are vertical flyback lines and would indicate
one or more of the tubes cathode drive circuits are defective.
As the picture is predominantly yellow this would indicate excessive drive to red and green guns. Check the red and green video output stages especialy any clamping diodes.regards from Vintie

Sony KV-27S42 no sound and audio blinks four times


+13 & -13 requires for Vertical Deflection IC and produced by Flyback Transformer, these volts will be produced IF Horizontal deflection circuit works properly. so try to check H-Out Transistor and its necessary volts / signal. Pls also mention correct Model Number to provide you more help.

Sony tv model no. KV - 19 APR 2


This is for a different model, but I had thin horizontal lines in red and had to adjust the tube for red. You may have a similar adjustment on your set.

The 6 blinks mean no horizontal. Check the horizontal circuitry. I'll look up your specific model later and post more details.

Sony tv no picture only horizontal line


The probable defective part is the vertical IC. If changing that does not resolve the problem, check the capacitors in the same circuit. Also, check for the proper voltages at the vertical IC. If the IC is not being fed its power, it won't work either. I don't have a listing for your specific model. If you can post the vertical IC part number (LA7837 for example), I can list the voltages per pin.
