The stand by LED lights up dimly, however, the TV does not turn on. Sometimes it even turns on, but it freezes on the screen logo. In our case, it didn't even turn on stand by | After opening the device, measure the voltage at 5 volts. If this voltage is low or pulsating, release the connector that goes to the main PCI, measuring the 5v again you will notice that it (5v) has returned to normal. if this happens, look for a 330ufx16v electrolytic capacitor, change it. In 90% of cases the TV returns to normal operation. | A normally orange capacitor, turn off the TV and place your finger on it, it should be burning hot | Eletrônica Muniz |

It doesn't turn on, it doesn't have 12 v, the primary power supply doesn't work. it only has approximately 158 v in q1 (7n60) | Z1 shorted (smd y8w33 zener 22v), photo p1(817) with leak, if it doesn't work, replace ic1(mjp 31) | If you don't have the SMD zener, put 2 11v in series. the ic that generates the pwm mjp 31 = ld 7531 = ku1 31a. The scheme I got was different. Good luck. | Oséias |
