Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SONY | ADP-160CR | Does not turn on, turns off during operation | Optocoupler IC43 1004 | Replacing the IC43 LTV1004 optical coupler | APL Technology (47) 99209-2255 |
| SONY | ADP-160CR | Sometimes turning off, sometimes it doesn't turn on | Replacing the MOSFET transistor Q31 NX7002K | replace o transistor mosfet NX7002k W4r | Adriano - APL Technology |
| PHILIPS | 42PFL4007G/78 715g5172-m01-001-004b | The TV turns on stuck on the logo, sometimes the channel starts, the command freezes and restarts. | U415 (G1084) replaced on the logic board | U415 replace | Beto , eletrônica box 4 |
| SAMSUNG | UN40F5500 | Good supply, main does not give signal. None, short on the 3.3v line that feeds the EPROM | replace of ic201 "near optical connector" and ic202 transistor "case" further right | Rodrigo cofferi | |
| PHILIPS | 32PFL3017 | HDMI inputs and digital channel tuning failure. | U502 open and U501 shorted | replace them | BARBADINHA |
| TOSHIBA | TV2096JMS U14R | Snoring in speakers | C613 220uf/25v shorted | Replace c613 | Marcelo Rodrigo Quinelatto |
| CHANGHONG | LT2618 LS15 | Doesn't start stay in standby mode. Power LED turns red. | Without 24v power supply. D841 shorted. | Replace D841 | José Félix |
| PANASONIC | TC-40DS600X | Goes into protection. turns on, image appears for a few seconds, error: LED flashes every 3 seconds | Problem with the backlight line, the problem is just one LED | The problem is in just one LED, however, the BD8289F controller goes into protection | A. Carreto |
| SAMSUNG | UB32C5000 | Dark screen | Check rd20 and rd55 on t-con | A. Carreto | |
| SAMSUNG | UB32C5000 | Dark screen | Intermittent t-con voltages max17122 and max17121 | Replace ics | A. Carreto |
| ATVIO | ATV49-UHD CV3458H-A50 CV3458H-A50 | Reduce backlight voltage | To reduce the backlight voltage, simply remove resistors PR109 and PR1 near the audio jack14 | When removing the resistors, the voltage change to 86v, minus 6 volts | A. Carreto |
| AOC | LE42H158I | Turning off backlight | bypassing the protection: on the inverter board there is no resistor in the R8159 position from the factory, many say to put a 10k resistor in its place, but the brightness of the LEDs is very low. I put a 20k resistor and it was perfect, great brightness and the backlight no longer turns off | ZW ELETRONICA | |
| LG | DV497H | Does not turn on or takes a long time to turn on cold days | C121 1000uf/10v as high ESR | C121 Replacement | Ederlin |
| TOSHIBA | MS7513MP3 | Volume control does not work. when turning the control, nothing appears on the display and the volume does not change. | Capacitors hc707 and/or hc708 (100pf) with severe leakage. | Only one capacitor was leaking. I replaced them both and everything went back to normal. | Técnico Rodrigues |
| LG | 47LG70YD LJ83A | The ST BY LED blinks but it doesn't turn on | Power on voltage values on the power supply board with strange voltages after photocouplers. | SMD transistor pnp Q505(sbt2907a) with leaks. Replace it. Note: PFC did not up even forcing power on command. | NelsinhoPira |
| TCL | L43S4900FS | Appears TCL LOGO and disappears, audio ok | After replace the LED kit, correct current reduction, remove resistors r314 24k and r341 12k, insert only a 15k one. | ToniTec | |
| SONY | FST-GTK11 | USB doesn't work | Cristal x1102 on pwb USB d169g01 | I put another one that starts with d169 it was good | orlando lott |
| STANER | SR-315A | Noise when increasing line volume, as if the potentiometer was bad | Broken trails close to ic3 pin seven, tsound are two islands just check it out and go for a hug | ||
| SONY | KDL-55W805 B | Turns on, show a symbol on the screen circling and turns off | Turn off WiFi TV card, if it turns on normally, replace this PCI | Tele Radio | |
| PHILIPS | 43PFG6825 | TV turns on, has sound, turns on the LEDs, but tsound is no image | Smd capacitor on t.con c28 board shorted | RJ Eletrônica |
