| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PHILIPS | 32PF7520D/10 LC4.3E AB | Doesn't work. power on led turns red but does not turn on | Power supply does not work, check 68ω/5w resistor on the power supply board | Andrade Sequeira | |
| PHILIPS | TCI-A10S-B 94V0 TCI-A105-D 94V0 L03.1L | I just ironed it and removed the solder and the TV turned on normally. | 3.8v missing on pin 17, it was 0v after a while I found the 2428 capacitor soldered with the 6426 diode | I just ironed it and removed the solder and the TV turned on normally. | genilson |
| SONY | KDL40R485A | Restarts 3x and goes to standbay and LED flashes 6x | Capacitor 39/50v | Replace smd electrolytic capacitor on 39/50v main board | Eletronica Cunha Pedrosa |
| ONEAL | OCM590 | It turns on more with a noise like a thump thump very quickly on the speaker | The two power supply diode in short d7 d9 in the power supply | Replace all the power supply diode, they are 1n4007, ready, the box was original as it left the store | Reis eletrônica |
| LG | RP14CB25A MC-059A | When plugging the TV into the socket, the standby bye LED flashes directly and the power supply's large capacitor remains charged as if it were the str | Z851 6.2v | ELETRÔNICA MUNIZ | |
| SONY | SHACK5 | Dead power supply | Ic501 | Hello. tsound was a defect in the shake5 sound with the power supply ci ic103 burnt, replaced it but the ic 501 was also bad I think its code is fa5612 which doesn't find anything it goes up the same but the fa5611 finds information and appears to be the same, it doesn't sell in bh but sells the fa5591 which is also from the same manμFacturer and same “pfc” function, I made the replace and it is working. Here's a tip. | Átila |
| PHILIPS | 33PT574A | It doesn't turn on, the LED keeps flashing and the power supply oscillates between 60v and 120v and it doesn't start. | Replacement of the 2540 100/25 capacitor | Buiu57 | |
| MAX-A55TD | SAMSUNG | Sometimes it turns on, then it doesn't turn on again, only with the panel LED on, if you remove the cable from the socket it won't work again | D06 in4148 that feeds pins 13 and 43 of the micro controller. | Just remove it and leave it without it, the voltage is 3v and it works great. | guinga sdia goias |
| LG | 50PJ250 | Shorted power supply board, activates the relay and in a matter of 2 seconds it disengages. with standby on | Cold soldering | Breno gonçalves | |
| PANASONIC | TC 29FX30L | Turns on and then turns off | Shorted diode d511 between flyback and vertical | After the replace everything was ok. | George Pontes |
| SAMSUNG | 29 TUBO | Colored scratches on the top of the screen, starts with few scratches and progresses over months. | Capacitor c304 | Replace capacitor c403 100μF 50v | Renato RPA SJC SP |
| MICROSOFT | XBOX ONE | The power supply turns on the white LED, but then turns it off | Insufficient power supply for the power supply drivers, low value electrolytic capacitor, near the STB power supply driver IC altered | Replace the two electrolytic capacitors close to the stb power supply ci | davi.sls |
| LG | RP-21CA85 MC-83C | TV arrived with little contrast, I checked the power supply and found a defect in the d502 power supply close to the r550 | Oxidation | D502 I put 1n4148 and run to another | eletronica miranda |
| SEMP TOSHIBA | DL3971(B)F | When you plug it into the socket it turns on and the channels work normally if you turn it off on the control or keyboard it turns on but the channels don't work so you have to unplug it again | When it doesn't work, turn off the channels, leaving them on standby, if tsound is 1.8 at the u206 output and just remove r10 of 100Ω | falcon eletronica | |
| SAMSUNG | UN46D7000LG | It doesn't turn on, but it hits the relay. | If we disconnect the cable that goes from the power supply to the main, the TV turns on and the LEDs light up. then the main board or tcon is completed. | I disconnected the cable from the tcon and the TV turned on, it turns out tcon, but in this case, oddly enough, tsound was bad contact in the flat cable fitting on the tcon, it actually turned off the TV as it moved in this fitting, I cleaned it with propyl isodine and eraser and just ran for a hug. | MIGUELTV |
| PHILCO | PH42E53SG | TV doesn't turn on, doesn't have 3.3 volts | Zener diode d 203 of 18 returns short | multsom | |
| PHILCO | PH400 | Low sound, but everything works. You can barely hear it, even with the volume turned up to maximum. | In this case it was IC8, an 8-terminal IC, close to the DVD motor connections | Replace the ic8: f16-100 hip | Romildo Behrend Schwartz |
| PHILCO | PH400 | The device doesn't turn on, it just turns blue on the front, on the volume button, but it doesn't activate anything. | It was discovered that it was a diode, which is on the IC side of the DVD motor drive, wsound tsound are 3 in the middle of 2 larger transistors: d33 | Replace the d33, even if it is good in terms of measurement | Romildo Behrend Schwartz |
| PHILCO | PH400 | The blue volume LED keeps flashing and the device does not turn on. the 5v and -21 power supply is oscillating, below what it should be. | After much research, it was found that the 33nf capacitor cb8 was responsible. | Replace for another good one, even if it doesn't show a defect. It is close to the photo coupler and the DVD motor connections. | Romildo Behrend Schwartz |
| PHILIPS | 20PT524A | I'm sound | Microns that are on the audio board. | Luan LG Philips |
