This TV has a normal image using the varicap but tsound is no sound, it stays muted and doesn't say anything! | Ic761 ic762 ic851 ic740 | Changing the ic761, ic762, ic851, ic740 changing them all is impossible, you have to replace them all. I replaced the elis and the TV said normal. God be praised! | Sinailson furtado |

Turns on, turns on standby, but does not give power. | In the secondary part of the power supply tsound are some coils that were glued with factory glue and after several years, they oxidise on the foot and cut contact, in my case it was the 15 turns power supply that did not release after the coil, I just had to clean it again and solder the coil terminal, be careful with this power supply that has a 36kΩ resistor close to the power supply's secondary integrated circuit, as the glue detonates the terminal and if it opens or changes, the 39 volt power supply at the output rises too high and burns the board sound system, then it got a bad sound card, blown capacitors, it's definitely a loud power supply and the unsuspecting technician forgets to check the power supply. Another detail, when testing the open power supply, with a voltage of 39 volts at no load, discharge the capacitors before connecting to the output board, because if the caps are loaded, when turned on, it usually burns the board again.... | Check the power supply, replace capacitors, and clean glue | MIGUELTV |

It works for hours at a time and the LED flashes 5 times | Poor contact in the flat cable when connecting the main board | To make sure tsound is bad contact on the flat, place a piece of insulating tape wsound the flat will be tightened to improve contact on the connector if you decide to leave or replace the flat cable. | Ricardovideoesom |
