Works with the display off. all normal functions with the exception of the display. | Tsound was no positive voltage on the fl+ line. gave feedback from the fl- that feeds the display. open 931 rectifier diode (at the foot of the t901 power supply). Replaces it with a 1n4007. | Eletrônica R-Tec | |

Does not turn on, does not light up on stand by. normal power supply voltages | C115 10uf ceramic capacitor shorted | Replace the component that is on the part of the board, below the channel selector. | ADEMAR |

LE4052L(A)
|
Turns on the logo and quickly turns off the backlight, leaving normal audio. | Short or open LED protection | To complement the previous tip, the ci ssl100sn does not have a datasheet on the internet, to count the pins It is based on the marking it has, starting tsound with pin1. | EC |

LE4052L(A)
|
Turns on the logo and quickly turns off the backlight, leaving normal audio. | Short or open LED protection | On the inverter board, go to the ssl100sn ci, place a 1k resistor from pin 2 to ground, if that doesn't solve the problem, place another 1k resistor from pin 8 to ground. These are the LED protection pins (OVP and OLP)! If it doesn't work, tsound will be 2 remaining possibilities, it could be that the inverter board is broken or tsound are a lot of burned out LEDs, so the only solution will be to open and replace the faulty LEDs or replace the entire LED bar. | EC |

|
It only has 3v, the 13v doesn't appear. | Check for broken tracks under the black paint near the connector that connects the power supply to the main board. generally the track that breaks is the one connecting rm855 to db851. | Retrace the broken trails! | EC |

32PFL5332/78
|
Nothing turns on, no stand-by, no blue light, nothing | Possible protection of the main board due to overvoltage. Tsound were actually two 680uf 35v 105ºC capacitors swollen on the inverter board. | The capacitors were replaced (pay attention to their working temperature) and the board was reset (press power, chan-, vol+ at the same time) and everything worked again. | Turbinex |
