When connecting to power, the red LED flashes, the relay engages, releasing all voltages, but the TV remains dead. | Communication failure between the processor and the RAM memory. | Failure in the banks of 22Ω resistors, inside the shield, in my case, r656 and r659 | Davi.sls |

On and off without stopping | Shorted screen | It has 11 trails and isolates 7 trails on the small flat on the left side, in some it works perfectly, not for everyone. | NILSON TVs |
| SONY |
ADP-160AR AA

Without 12 volts | When you turn on the power supply, it goes up to 5v | Ic 81 ( das2 ) | DEO ELETRÔNICA |
| PANASONIC |
TC-55AS700B
LA51 |
Does not turn on, backlight flashes and activates standby LED protection flashes red 1x | See possible problem with the rulers, each bank of LEDs lights up with 43v. If the LEDs are ok, check the power supply board. Tsound are 6 smd tr on the power supply board responsible for regulating the negative of the LED banks. One of them may have a short circuit, measure carefully as they are pnp transistors | Replace the shorted transistor 2sb1181 or replace the power supply lacquer if you can't find the transistor to buy | rafaelmoraes99 |

It works for ten minutes and then the power supply drops to around 50v (note: only with the lid in place) | Strg8656 heating up and having problems, replacement of the strg8656 key switch, but as I didn't have the same one, I did a datasheet search and verified that the strg5653 had identical pinouts, and even heats up less than the original. | fabiusmax | |

Backlight off, LEDs are all good. | Power supply board, defective LED driver circuit. | Electrolytic capacitor e108 with altered esr 330μF x35v 105º. | RNSPTEC |
| LG |
32LE5300

Turns on, f16 appears on the display and then turns off. (false cooler error) | Voltage of 37v normal in c3300 but without audio and it was not the output. pin 40 of ic2006 could not go to zero if the cooler is spinning. | Transistor q2006(nb) was open, which led q2008 and q2010 to give negative voltage on pin 40 of the ic2006 processor. After exchanging the q2006 for a bc817 it started working again! | Ruizyn |

No audio. | The solution I found was to loosen the pins of the R and L audio connectors on the board, and using a 10uf/16v capacitor in series with each of the pins, I connected a wire directly to pin 12 of IC1 TA7176. and problem solved! | MARCONES DE ARARIPINA -PE |
