There is two possible defects in your circuit.
However, if the led blinks for about 10 times your tuner is defective 90% of the time.
To be sure if it is a tuner or an IF circuit. Isolate the tuner first then the IF circuit.
you can check this using a scope.
Although to be 100% sure of this we would need the Chassis type as Sony use different fault codes on different chassis.
