Turns on, works for a few minutes and turns off | Measure and monitor the 3.3v voltage of the power supply. It was observed that after a few seconds with the TV running, the voltage dropped to almost 0v and returned to 3.3v, causing the TV to go into standbay. | Replace the ci u201 on the power supply board. | miro maciel |

TV arrived with a greenish screen at the top and the image jumping to black and white | After checking all the components, I didn't find a defect on the kinescope board, so I went to analyze the power supply board and found the rt801 to be faulty. Its function is to magnetize and demagnetize the power supply tube and coil. | Replace the 2-point RT801 thermistor for 1 3-point one and go out for a hug! | Jailson Lima |

TP-2052N
|
When cold, the power supply was pulsing and the speaker was hiccuping. | Change the power supply capacitors c913 and c911 | When out of the socket, put a jet of cold air on the c913 c 911 capacitors and see if the power supply starts to pulse, then heat these capacitors with a thermal blower, if it turns on, then just replace the capacitors and go for it. | lucas-venzke |

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 |
