Does not come out of standby does not turn on | Q1003 mosfet | I checked the 5 volt voltage at the power supply and it was normal. I checked the reset power detection circuit. the voltage was low at 3.3v on pin 3 of the ic1005 regulator, I replaced it and it didn't solve the problem. Following the line I verified that the voltage was coming from the q1003 ci mosfet 9933b pins 7 and 8, I replaced it and the solution was resolved, the voltage returned to normal and the TV turned on normally again. | ADRIANO MIRANDA |
