| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PHILIPS | 15PF9936 17PF9945 23PF9945 | TV doesn't start, red LED is on but doesn't turn on | Ver resistores 68r/5w psu | Replace for 68r/10w | Mário Martins |
| PHILIPS | 42PFL3403 | Doesn't work, power supply doesn't start | Diodo smd zd103(20v), u101(fsq510) | Mário Martins | |
| PHILIPS | 14PT110 14PT112 14PT220A | Half screen and with characters stacked from top to bottom | Change without testing vertical ci tda3653 | Closed from the right to the middle of the screen, normal sound, on the left side a good image and only characters appear when the TV is turned on. The channel number appears stacked from bottom to top. After leaving the channel number, tsound are no more characters such as menu, brightness, etc. You can't even enter service mode as it doesn't appear on the screen. It is unimaginable to think that the vertical ci could cause such a defect. replace tda3653 without testing, put new one. | cesar |
| PHILIPS | 14PT110 | Half screen and with characters stacked from top to bottom | 1st change tda8360 and if that doesn't work, change it without testing vertical ci tda 3653 | cesar | |

| SOM GRADIENTE | AS200 | Doesn't start. display off. | Transistor t500 2sd1766, on the transformer board | Replace t500. In my case, I didn't find it with the same reference, and I put a bd135 in its place. and just invert the position on the board. | MARCONES DE ARARIPINA PE. |
| SAMSUNG | CL14C600KJ | TV, stopped when turned on, the LED does not light up and without +b | After the power supply stage I detected r821 - 100k open special 5-band resistor it could also be r821b that works in parallel | José Santana,,, Sergipe | |
| SAMSUNG | T24B350 | Does not turn on completely inoperative | Change voltage regulator strw 6053 s and 47j / 1kva capacitor that is on the IC terminals | Denilsonti75 (epinfor) | |
| SAMSUNG | 24B350 | Does not turn on completely inoperative | Change voltage regulator strw 6053 s and 47j / 1kva capacitor that is on the IC terminals | Denilsonti75 (epinfor) | |
| PANASONIC | SA-AKX80 | Does not turn on completely off | Power supply ok, the defect was r1042 0Ω open and ic1002-tps54240 shorted very close to it schottky diode code 36 = ss36 smd and also replace ic1003 -tps54240 shorted and schottky diode code 330 = sr330 smd with leak, device was replaced it was ok working | Defect resolved | Andre Técnico Posto Autorizado Panasonic |
| PHILIPS | 40PFL3805D/78 | TV completely inoperative | C502 on the power supply board shorted (100pf/1kv) | Replace the same | Deivid Vanzuita |
| PANASONIC | SA-AKX80 | Stereo arrived, completely turned off, pressing the power button does not turn on, nor does the LED on the display light up | Defect in the power supply, in the line that feeds the integrated circuit of the power supply c21 - 1nf 50v smd changed, the sound was changed, the display turned on | Defect resolved | Andre Técnico Posto Autorizado Panasonic |
| PHILIPS | FWM208/55 | Locks functions/slow and does not tune | Crystal with corrosive glue and washing the PCI under the CD | Ângelo MG | |
| LG | 42LV345C 42LV3500 42LV3700 32LV3500 LC420EUN ABDV3 | No image, just white horizontal bands. When disconnecting one side of the t-con flat, that half of the screen turns white. the same happens on the other side. | It makes you think it's a screen defect but tsound was no oxidation on the flats and no heating of the screen flats. | The defect is in the t-con. the ic boils! replace and run for the hug! | PL ELETRÔNICA |
| ELSYS | RECEPTOR OI MESMO NADINSAT | Update bar directly on the screen, updates and updates again | Nand next to the processor, ml01g200 defective, | I took another one from a scrap yard and it started working again. | davi.sls |
| SEMP TOSHIBA | TV1030 TV1431 TV1415 TV1451 TV2015 TV2016 TV2016 TV2051 TV2086 TV2157 TV2158 U18 U18 | Noise at the power supply killing the voltages (all) | Q865 | Replace | Alextecnico |
| SAMSUNG | UN40J5200 | Enlarged image. It looks like a zoom was made and it doesn't go back to normal. In a close up, people's noses appear upwards. It is not possible to access the screen footer. | Screen defect. | Screen replacement. | arock |
| AOC | 32W053 | Does not turn on, LED blinks | When checking the power supply, it showed normal 5v and it didn't have 12v and 24v and the main board sent the voltage to the "ps-on", the defect was in the voltage doubler, it was supposed to have 300v and it only had 160v | 0.1 resistor and doubler c.i fan. | Sylvox |
| SAMSUNG | PL43F4000 | 5v from the power supply pulsing stand by off | Defect in the 2 blue capacitors cq804 and cq805 | 2 blue capacitors cq804 and cq805, both 2.2nf x 1000v, next to the diode matrix dq807 and dq808, replace them even if they are good. | SILNEI |
| PANASONIC | TC-20C7 | Vertical with approximately 10cm in the middle of the screen (you can also notice the shrunken characters) | Cause r422 of 21k close to ic401 (vertical) this resistor usually separates. This television is a champion in terms of component rust. If the aforementioned resistor is normal, check the other resistors close to the vertical ci. | Norte Eletrônica |
