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
Ed
That is not a good USA model number, somthing is missing probibly after the 27 part.
