Sony Bravia KDL-42W655A TV five blinks error code

Hello, how are you doing?
I´m troubleshooting the Sony Bravia KDL-42W655A TV and I need the schematic. I had tried to find it, but with no sucess. Could some  one help me find it?
I had found the service manual, but there is no schematic  in the service manual.

I´m having a problem that is indicated in the led error system like five blinking. As per the service manual, it recommend to start testing the 12,5 V at the FPC connector, and my board does not have this voltage,  it has mV at the fpc power connector pins. I  need the schematic to understant which is the path I need to follow for verifying the 12,5 V and udnerstand in which point it is missed.
Do you have any suggestion or this model TV schematics?

thanks
Houari
