I have a Sony KV36FS120 that will not turn on. No relay clicks, but get 9
blinks on standy by led.
Is this the diodes in Power Supply?

I believe 9 blinks is zero-cross.

First Attempt To Turn On In Service Mode (Display,5,Vol Up,Power) If It
Turns On The Problem Is The Zcd Circuit. Replace (Don'T Check) D647 (10erb20/
Nte 125) D690 (27v Zener) Q605 (2sd744) This Should Fix Most. If Not Try
Following: D640, D641, Q691, Q690, Q606, T603 (Noise On Sec Winding)

True, replace ! do not check! D6301.on the G board. Can use 1n4007 Or ECG 125 I preffer the first.
Also if D 6116 is on the board replace it with 1N4007.

Any bad solder connections on the SMD in the Zero det. circuit will kill the signal.

Also check the relay Driver Q691 (2SA933) and D647 (10ERB20) this diode was a no start up problem. The MCZ's 3001 Ic 's could be bad.

This may get you going.
