Does not turn on standby LED on | Measure the power supplies in my case it had 3v3 standby, 24v and 2v4 poweron, it was stuck on that, on the main board it only had voltage of 1v5 and 3v3 | On the signal board the dc dc converter responsible for the 12v was defective they would be u206 and q200, after that all voltages returned to normal except the 1v1 voltage and the dc dc converter responsible for this voltage was also bad which is composed of u205 and u207 | Ariel Santos |

No image, backlight on and screen slightly bluish due to the brightness of the LEDs. | Def. on one side | Follow the tips on the forum, disconnect one of the flat cables from the t-con, (attention you will need to make a continuity jammer from the r354 to the other side, the r351 in the r354 leaves 12v and enters the r351, you have to pass through it if it doesn't burn at t -con , after the repair, keep the jamper and. | valdir ,Macajuba-Ba |

No sound in any function, dead audio, no low signal in the Audio stage | Fet smd of position q3 (a03401) on the main board with its "power supply" output with only 7 volts, the correct one is 12 volts. | It was just a matter of changing it and the problem was resolved. | MIGUELTV |

PHT550

Totally inoperative | Fuse f1 open and resistor r54 toast (open) | I replaced the fuse and connected it with a series bulb. the fountain began to crackle. I turned off the device and after checking the power supply capacitors, I found only the r54 was toast. In this region, the manμFacturer added glue to secure the power supply's electrolytics. Even though the glue is dry, tsound was probably a current leak. I replaced the resistor and everything went back to normal. As a precaution, I also replaced the following electrolytics that tend to replace over time: e1, e3, e5, e9, e10 and e11. | Técnico Rodrigues |
