    Same problem - I have a Sony kp-53v45. Ticking appears to be coming from the Flyback. (With cover removed) A small light with a black cover over it near the flyback with a lead leading into the flyback on the motherboard (diagnostic indicators?)  is flashing with the beat of the thump noise indicating a possible short? Sounds like flyback transformer attempting to power up and shutting down cycling over and over fast. Picture tubes never light up. Is this a problem with the input side or output side of the transformer? How can I diagnose this tv set further? Any hep greatly appreciated! - Scotty

No Picture / No Sound


What was happening before can put you close to what when out. If you had color problems or sound, or even picture going small. these are symptoms that causes the set to go out. If color look in the convergence area and look for blown fuses and bad resistors. If just went out the look at horizontal output transistor.
