After several repairs to the power supply (primary sector) the device re-armed the stand-by power supply, however the main power supply had no feedback circuit correction (it reached 150v and permanently disarmed until the capacitor discharged) | Micro with defective I/O port disconnecting the feedback correction from the main power supply. | Just remove the smd transistor "7573" near the +b filter capacitor to solve it.

Customer said he used air to clean, probably resulting in cold welds | I resoldered the entire power supply board, I replaced the 2 capacitors next to the 390uf/25v power supply output, I placed 2 of 1000uf/25v | After all this I still needed to inject 13v into the power supply output after that the TV turned on and tsound were no more problems | Petrukio |

Turns on without image - back light turns on normally and has sound! | Possibly defect in the v-con flat or in the LCD itself | I tried updating the firmware and it didn't work, after removing one cable at a time from the v-con flat that goes to the tcon, it was possible to find out which side of the LCD was defective. palliative solution: a 0.3mm insulating tape was placed on the 60-way flat cable, isolating two pins, 14e15, so the TV set returned to having a normal image. | ReparoSmartBR |
