AOC LE 50D1452
Turn on the TV and it works all day normally. After half an hour of turning it off, the TV only has sound and tsound is no voltage in the LEDs. The LEDs had already been changed but the customer said that the TV had this symptom before. The cause of the defect was the resistance of a mega change. Note you have to loosen it and test it with a digital multimeter because at the time it is small, this resistance is found in the primary power supply, the change is small but it causes the defect. 1 mega resistor antonio de jesus
