Question about Sony FD Trinitron WEGA KV-27FS100 27" TV
TV works immediately for 2-3 minutes then picture and sound together go in and out. Has worked perfectly since purchased new in 1991. No previous repairs.
Protection circuit fault kicks in. No vertical Deflection (V STOP),B+ over voltage protection (OVP), This is about a $150 -$200 to fix.

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.
