| PHILCO | PTV55Q20 | 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 |
| PHILCO | TV21M SS TUBO | Only on standby. | Burnt fly back bsc25-0233y can't be found anywsound. | Replacing the original fly back with a bsc25-0230z, changing capacitor c453 from 272j/1600v to 562j/1600v and also c457 from 153j/1600v to 183j/1600v and increasing the vertical IC and horizontal output heatsinks. | Max Andadra |
| PHILCO | PH24M LED A | Turn it on and off | Changed flash memory, solved, it started to turn off at times, if you press volume it turns off, it doesn't accept power off, it works for several hours, | Replace button board functions or remove key pin, disabling keyboards and maintaining sensor. | |
| PHILCO | PH28863D | Dark screen | Burned out leds | Changing the LED bars, problem solved | Will Rogeres |
| PHILCO | PTV32D12D | I'm sound | Headphone jack | Replace | CARLOS SILVA |
| PHILCO | PB500BT | Not switching auxiliary input on plug p2 | When opening the jack I saw that the switch was disassembled, I reassembled it and it returned to normal | Paulo Teixeira | |
| PHILCO | PH24M LED A2 | 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 |
| PHILCO | 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 |
