The power supply board is failing. There are twi integrated circuits in the horizontal drive circuitry that have to be replaced. The original integrated circuits are the same type and you will see written on each..."MCZ3001D" and need to be replaced with Sony # 670581001 or the "D" board with those parts on it needs to be replaced. The cost of the entire board is high-about $375.

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.
