Television and Home Theater

Sony Trinitron KV-27S30 with black screen and blinking 4 times. 

Need some help on this one.  I have traced this to no 13v feed to IC541.  No 13v from the flyback.  I do not know what feeds the flyback transformer.  I am having difficulty chasing the power supply voltage in the wiring diagram.   If anyone has feedback on this, I would appreciate it.  I do not want to just start throwing parts at the unit.  I did find one terminal on the flyback that  showed 146v.  Appreciate any advise.

Thanks

Hello guys great site. I have a Panasonic projection PT-47WX53G that when hit power button the standby powers supply clicks on you can hear the audio hiss, when channels turn you can hear the mute in the audio hiss telling you that the tuner is functioning, but however the HV circuit comes on for 2 to 3sec then shut off. When it does this you hear the relay click on then off. Please help I am an Electronics tech that specializes in Home and Car Audio. 1st attempt on TVs. I have the tools and safety equiopments.
