It didn't turn on, it stayed on stand by | Ci of the aoz1031 main board, just change it and it will work again, to see if it is the main board, disconnect the cable that goes from it to the power supply board, if the screen turns on it is a sign that the power supply board is good. | Alice eccel | |

Burning leds | Voltage of the LEDs with 210.5v | Replace the leds and replace the value of r9113 to 1.2r (voltage drops to 184.5v ÷ 60 leds = 3.075v for each led) | Evando Viana |

It turns on immediately and restarts (in a loop) sometimes it works normally. | Short on the 1.5v line (1.5v voltage only with 0.98v...) causing the shorted dft smd capacitor c1170. | Replace the c1170 for another identical one. good luck... | Evando Viana |

Turns on the red LED, when you press power, the red LED goes off and comes back on, sometimes the green LED starts blinking | 5v step down supply on main board | Responsible ci, I replaced the mp1484, with a small replace, since this ci has the gnd pad, I had to scrape the varnish off the board to create an electrical and thermal connection, improving heat dissipation. | Davi.sls |

Without image, with sound. | Burnt out LED bus. solution to change them all, nearest LED 2835 6v (40 pcs). Difficulty positioning the reflectors, but it looks good. Modification to the original 145 V bus power supply, very high. removing the 1r smd resistor from the line drops to 135v. | Replace all LEDs, 2835 6v, remove 1r smd resistor, close to the connectors and the voltage drops, with current. increases the useful life of the les. | Giovani Pires Bitencourt |

Standby only. If you insist on unplugging it, it turns on with green screen characters and locks. If you insist more, it turns on and works for a while. | As1177l regulator (close to the main IC) 1.5v changing between 1.1v and 1.4v. | Replaced and resolved by maintaining 1.5v turning on and off normally | |

TV with a whitish image with tremors and the LCD blinking. | V board with, breakout components. | The line of smd capacitors cd 12, 11, 10, 9, 8 and 7 with resistive leakage of 48r, causing the failure of the cd7 cpacittor smd 5μF, which was the cause of the leak in the line | RNSPTEC |

No image (blue), white image, locked image, sometimes connected with green stripes. | When you flick the TV the image comes back, one of the flats, on mine on the right. cold solder on the acf, on the side that presses on the v-com | Tsound are 2 screws that hold the v-com in the housing, if you loosen it, that solves it, in my case I still prefer to solder with tin only on the side written 0821-a (on the flex) the 14 pins | lucian oliveira 61991271532 DIGITAL TECH |

Turns on, standby comes on, press power, the TV turns on, writes Toshiba and very quickly the logo goes off and the LED turns green and stops functioning, it does not obey commands, nor does it accept turning off, in other words, it stops operating..... | So I was unsure if it was a backlight, as I had a new kit and had the cable that goes to the rulers, I tested it from the outside without having to disassemble the TV and confirmed that the defect is in the LED panel itself. | I had already picked up a 48" that did this but I didn't remember that the defective kit makes this model act as protection and stops the processing. | MIGUELTV |

The sound increases by itself, tsound is no point in changing the keys. green LED flashes intermittently. | Two smd transistors that are on the infra red board, replace the two npns, q101 and q 102. | paulo cezar esteves | |

When turning on the power, the green LED flashes quickly for a few times and then the red LED starts flashing in a loop, once and pause, once and pause.... | So error 1, I put a LED kit on the outside without opening the TV and it resolved it, then the LED bus failed. | Replace panel/led kit | MIGUELTV |

Tv philco ph32e32d cutting the sound or no sound | 100ufx16v ca815 and ca804 replace solution | This TV arrived at my workshop without sound, I updated the software and resoldered the board in the audio processing area but it didn't solve the problem! So a friend gave me this tip that I want to share with you! defect, no sound or the sound is choppy! | GEMASI |
