Sanfalla tell me if it is bridging with a 1K resistor I entered 5.3v of standby and power ON.
Ok I tell you this source of power starts by connecting the resistance to the SUB ON pin so it didn't start me before.
The test was performed again and the voltages remained stable. The fault would already pass in the main.
Well I share the experience after doing tests at the source and following the error of failures in the service manual and the help in the forum all pointed to the Main which was changed but followed the error.
Finally I decided to review everything and not focus only on the fault marked by the manual. I check the LEDS and surprise 3 LEDS out of service maintenance and SOLUTION.
