Good evening friend, check the source voltages and insurance is being protected by OCP if you have that circuit or by XRay, I recommend you check the circuits of those protections greetings ...

hello buddy: try changing the R814 of 0.68ohm x one of 0.47ohm ... or you can try welding a R of 1ohm in parallel with the R814 ... then you see if it no longer goes off ... if it goes off change the R805 of 0.33ohm in the primary of the source x an R of 0.22ohm ... the R805 is between pin3 of the STR-w6735 and mass of the primary of the source .... when the R805 of 0.33ohm It is devalued, you can turn off the TV erroneamemte ... control the voltage of the + b ... must be in the 133v in C814-820 -... comment results ... ok .... greetings!
