Any set can be repaired it is the question of the cost and the availability of the parts.

The fuzzy lines with static noise is probably from an arcing in the high voltage multiplier or in the flyback windinngs. I am very sure that the flyback assembly with the high voltage multiplier, and most likely the horizontal output transistor will have to be changed just to start. It is also possible that there may be some failure in the power supply as well.

The set would have to be serviced by an experienced TV tech. As for the cost, it will be a bit expensive.

No sound on Sony Triniton Model-KV-35V35


This sony had problems with tuner and a little small sound board that stands up on the main board. If you know how to solder you could repair. If not you need help from tech.
