Sony wega trinitron(1999) KV-36FV15 Moved tv now audio no video


Seven blinks, pause, seven blinks, etc. means "Horizontal deflection stopped" and indicates a serious problem, probably on the D or DZ board (whichever is applicable).

If this is the case, the TV will have to be serviced by a professional.

I hope this helps :)

Sony Vega Service Codes


KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.

There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.

If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.

Problems with Sony FD Trinitron WEGA KV-36HS20


The set is going in to the protect mode.

There are some components that have become thermo sensitive from age and use. After the defective parts come up to their operating temperature they go out of specs.

Most of the time this type of problem comes from the power supply. Sometimes it is from another board that is causing the shut down.

The fix is to start by replacing the power supply for a start. If there are still any faults, the tech will try the boards to zero in on the defective one. Once he locates the defective board, if it is not worth to service, he will leave the new board in the set.

This type of repair can be in the average range between $200 to the $500 range depending on the exact fault. This is providing that the fault is not inside of the screen itself.
