Burnt output, cold solders due to heating and incorrect connection to the line signal input | To test, connect one board at a time using the ground as negative and disconnect the wire with the 22k resistor that makes the bridge, don't forget to discharge the capacitors with the 5wts resistor to change the tda 7293, any carelessness can damage the input part of tda sign | Tda 7294 didn't work, I put the tda 7293 it worked perfect, in the pre zener diode 5.1 volts and c.i. tl 072 (tsound are two identical ones on the pre board, the larger one is from the echo effect) | RICARDO <small> |

Duplicate image | Take off flets | (solved) good afternoon everyone, I discovered how to solve this problem by removing 4-5 tracks from the flét cable that comes out of the v-board - with the gold colored cable, take off about 4 tracks on one of the sides, if the image still has a problem, you can take it off on the other load, to reconnect the ones that weren't, place a rubber between the metal protection and the flet wsound it was disconnected to secure it, insulate the underside of the v-com board to avoid posing a short to the housing, mine worked fine, it worked perfect, thank you | silio serpa |

Power supply relay knocking, no voltage vs and goes without 5v, it also applies when it works and keeps turning off for no apparent reason ok | R122 r123 r124 1004 or 1mg remove clean glue replace, check voltage with digital multimeter on each one, tsound should be 90v on each one as it is a divider | Luiz Técnico | |

TV had sound, had black light, but dark image, main board and power supply, t-com good. | Display board with shorted capacitor, c103 | Turn off one of the flets to find out which side has the problem. whichever side is bad, has half of the screen white. and just replace the 10 midro caspacitor | ELETRONICA MOISES |

After a lightning strike, this TV arrived at the workshop completely inoperative, I changed the ci 601=srtw6554a, it turned on the standby but very weak, not even the relay set the secondary voltages, all low | Q605=2sc1815 | I replaced and ran to another one | Antonio Carlos (Eletrônica Renascer) |

Channel -b with number works correctly, sound cuts out and heats up output transistors, incorrect bias adjustment even without signal the transistors heat up too much. | Defective ci-tl072, ci-1002 (in my case I replaced the transistors and resistors) and some capacitors with low capacitance (47x100) and also a 27vx1w zener diode | Replace the mentioned parts | Edmundo |
