| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PHILCO | PH28N91D | No picture | Causing pd10 diode | Swap and run for the hug | Daniel, eletrônica ideal |
| PHILCO | PH28N92D | No picture, good LEDs | Diode pd10_ SS310 shorted | Daniel, eletrônica ideal | |
| TOSHIBA | TV2051NAV U18 U18 | Doesn't turn on | Microprocessor | Cleandro da Silva bertolete | |
| PHILCO | PCX1600 VEX.PH.HOME.048.REV.0 ABRIL/2019 | mute box | micro activating the Mute, probable defect in the micro. I can't find the ic, I replaced r106 from 1k to 10k and the box started working again on r106 | JOSIVAN | |
| LG | MS3047G | Does not turn on unlit panel | 2.2mH inductor open on the electronic board | lucafer | |
| PHILIPS | 50PUG6654 0000 | normal sound but no plot | broken display | I isolated the last 8 lanes on the left. Dormiuuu... good luck! | Jhone Eletronica |
| CENTURY | MIDIABOX B4 | Doesn't turn on | IC U935 - Defective SD6835, no power supply at pin 3, the defect is not the resistor R1425, the defective IC that kills the voltage at pin 3 VCC of the IC. | replace of IC U935 - SD 6835, can be replaced by SD6834. | Renne |
| PHILIPS | FWC507 | Display off | Resistor 4.7 position 3211 transformer board. | JMC Eletrônica e comércio | |
| PHILCO | PTV42E60DSWN | The LED bars do not light up, sometimes they turn on normally. When cold it was defective, heating the capacitors it would work | replace of electrolytic capacitors 100uf x 100v cb2 and cb17 at the output of the led drive power supply | Sérgio | |
| MACKIE | PROFX8V2 | Low gain on microphone inputs or noise on gain potentiometers | Replace 1N4148 SMD diodes, they are all on the board and tsound are p10 and XLR connectors. | ||
| LG | CJ65 | does not turn on and all power supplys are ok | 24mhz crystal x500 if the crystal heats up the sound turns on | replace 24mhz x500 crystal if you don't have the original, adapt a really large one | Beto2828 |
| SAMSUNG | CL21C650ML | When connecting to the socket, the LED flashes 1 time and remains off, +B goes to 130v or 140v and drops to 0v, power supply capacitor charged | Resistor(s) R821B, R821 or R819 | check if one of them is open or open and make the replace | DTEC-ELETRONICA-Massapê-ce |
| SAMSUNG | UN46F6400 UN46F7500 | Hitting relay | altered leds | ||
| PHILIPS | 32MF605W | No sound, picture ok. | No Vcc Voltage on the audio processor. Check voltage regulator 7006 | Aaron Fresno | |
| VIZIO | V047LFDHTV10A | Backlight works but no picture. | Fuses ok. T-CON failure | The only solution was to replace the T-CON | Aaron Fresno |
| TCL | 50P755 | No sound | ADVDD voltage below 3.3v, on pin 9 of the AD82088 sound integrated circuit, oscillating around 2.7v. | The easiest solution I found to solve this defect was to add a resistor in the RDX102 position of 0R, it is on the right side of the sound integrated circuit, close to the heat sink, thus restoring the necessary 3.3V voltage. | Eletrônica Renova |
| VIZIO | M3D460SR | Noisy picture and, when it has been running for a few minutes, it turns white, | 1.2V voltage regulator on T-CON (U205) faulty | Replace voltage regulator | Aaron Fresno |
| VIZIO | M3D460SR | Noisy picture | 1.2V voltage regulator on T-CON (U205) faulty | Replace voltage regulator | Aaron Fresno |
| PHILIPS | 50PFP5332 | Dead, LED flashes 6 times | Check C601 e C609 | Aaron Fresno | |
| VIZIO | P50HDTV20A | Hang up | Power supply problem | Replace all capacitors C201, C202, C203, C227, C271, C272, C282 and C283 in the power supply. Also check C261 and C275. | Aaron Fresno |
