Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | UN32F4200AG | doesn't start | SHORT CAPACITOR | replace OF CM801 (101K 1KV) | ROGERIO |
| TCL | 65P735 | When turned on, the logo flashes and the screen turns off | Short circuit in rectifier D601 (MUR3200) at the power supply | replace | SANTOMEL |
| SAMSUNG | UN40H5500 | Burnt backlight | After replace the LED bars, the LEDs blinked non-stop. After analyzing the LED driver circuit, it was verified that the 0R resistor (JP827) on the Ci driver 7014x side was replaced to 30ohms. | replaced the JP827 jumper resistor and the backlight worked normally | Ricardo Dapper |
| PHILIPS | 65PUG7406/78 | Does not turn on standby off | C322 c328 shorted on main PCB | Replace c322 or c328 | |
| HBUSTER | HBTV-32D05HD | In stand by the power supply becomes high and the capacitors are damaged. | When replacing the 470uf capacitors, also replace the two 47ufx50v capacitors in the power supply primary. | Ricardo | |
| SEMP | 2015 U18 | White screen and reduced frame | D840 Zener that goes on the base of the q840 did not go to the 5v for the micro | Jaspion | |
| STANER | SR212A | Low volume potentiometer good | Capacitor and oxidation | C22+c34 dry without capacitance both 10nf 25v in my case I put 10nf 50v | ELETRÔNICA MUNIZ ABRANTES |
| PANASONIC | 49ES630B | TV turns on normally with sound, no picture, but LEDs on | T-CON Board Defect, shorted board | replace capacitors c135 and c136 on the t-com board | Eletrônica EMB |
| LG | 55LD650 - SA | Sound and picture in slow motion | replaced processor clock. | Soldering of L208, R211, R212, C229, C230 and X903 crystal | Osvaldo AB |
| PHILCO | PH49F30 | Stuck on screen, please wait | firmware | Download the update firmware file. With the pendrive connected, plug the TV into the socket with the power button pressed, keeping it pressed for about 10 seconds, until the LED starts flashing quickly. | Davi.sls |
| SONY | KDL-40R485A | The picture appears and turns off, the LED flashes 6 times | protection activating due to weak or altered led or bad display | disabling the protection solder a 1k or 10k resistor pin 31 of the ic9500 BD9397efv to ground disables the protection | Beto2828 |
| PHILCO | PCX5600 | Does not turn on, low battery | It turns on, but as it was out of battery it then turns off... no signal when connecting the charger cable | Replacement of the power supply board Photocoupler (U3), and replace of the SR3100 diode (D6). | Innovast |
| SAMSUNG | CL14C600KJ | The picture only appears when ajust screen level | One of the rgb Zener diodes | Francisco Alves Ferreira | |
| PANASONIC | TC-L42E30B | Turns on with a dark picture on one side and turns off | Defect in LED buses and inverter board | replace the LED bars, in my case tsound was also a problem with the inverter, I solved it by re-soldering all the resistors on the inverter board | ITALOPACZ DOORNEL |
| SAMSUNG | PN43H4000 | Does not turn on, voltages appear and drops | C5802, (22uF x 50v) with low esr | Stiltec | |
| SAMSUNG | QN55Q60AAG | Flashing screen and with stripes | Shorted CKV line | remove the 10 CKV resistors on the left side of the display, it worked perfect | ITALOPACZ DOORNEL |
| PANASONIC | SA-AKX710 | The device turns on, lighting only the colored LEDs and then turns off. | power supply, SMD diode (with flashing) connected to pin 15 of IC1501 | Diode replacement. NOTE: I didn't find the specifications for this diode, I put a board cutout on it and it worked. But based on the characteristics of wsound it is positioned in the circuit and the diode impedance test, I came to the conclusion that it is a fast diode, with a higher voltage and is not a schottky. If anyone discovers a specific diode that is correct, please repost a tip informing us to help everyone. | Gênios Eletrônica SJ |
| LG | 42PC5RV | No sound/no sound | Capacitor c824/c318 | Just make the replace! And left by; barbieri | Cleber |
| ACER | ED240Q | LEAGUE WITHOUT picture | 12V DISPLAY LINE SHORT | D201 DIODE ON SCREEN SHORT AND FUSE CLOSE TO 3A OPEN. | TECNOBRU SBC |
| LG | 42PJ350 | Does not tune channels | 22Ω resistor connected to pin 71; from IC 602 or the bad IC itself, in my case it was the IC | Replacement of IC 602 or resistance connected to pin 70 | Cabeça |
