Tcl Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP TCL | NãO LEMBRO | Lower LED current | Increase resistance connected to pin 6 of ci gb98 bg98a | Davi.sls | |
| TCL | L32S4900S | Does not turn on, no stand-by | Power supply | Diodo hbr5200 (ds2) | Brackmann |
| TCL | 50P65US | LED current reduction | To reduce the current tsound are two resistors connected to pin 2 of the IC LED driver, one with 91k and one with 39k, just remove the 91k | Above tsound is a reduction tip but it is wrong the pin mentioned is the din pin, it is not reduced on the din pin but on the iset pin of the ci which is the current monitor pin | Ariel Santos |
| TCL | 50P8M | Voltage reduction | Resistor 39k | R608 between the ci feathers of the led | Wesleyborges7 |
| TCL | L32S4700S | Doesn't start | Change 3.3v regulator the same one measures 2.4v | Lucas Venzke | |
| SEMP TCL | 50P615 | LEDs don't light up - it seems like the LEDs are defective, but in this case it wasn't | Sb3200 diode in position ad603 - I didn't have one like it so I put a mur460 in its place | George Luís | |
| SEMP TCL | 50P615 | LEDs don't light up - it seems like the LEDs are defective, but in this case it wasn't | Sb3200 diode in position ad603 - I didn't have one like it so I put a mur460 in its place | George Luís | |
| TCL MULTILASER HISENSE | 43C350KB | On, the standby LED keeps flashing alternately between green and red and it doesn't go away | I checked the "open" LED bus, as I didn't disassemble the TV, only through the LED tester I could see that the LED circuit was open, that is, the TV acts as protection because tsound is no consumption/load on the LED bus. with an external bus with 6 volt LEDs (3 strips of 7 6 volt LEDs) I simulated the consumption on the TV and then the TV started working and I could see the image with a flashlight.... | LED panel defect, I didn't find it in any supplier. The LED panel of this TV is American Hisense, I found it on Aliexpress, follow the link right after (on the body of the rulers it is described: hd425y1u71-t0l2 2020092801 svh430ag9): pt aliexpress. now that I disassembled it I could see that the kit is made up of 03 rulers with 08 LEDs each ruler and they are 03 volt LEDs... ok... the code on the body of the rulers is: crh-bxbt43y13030080309urev1.0 and also hd425y1u71-t0l2 +2020092801+svh430ag9, but I don't advise anyone to disassemble this TV, it's infinity edge and think of a train that's bad for changing and for it to be perfect after the replacement... mine did but I promised myself never to get this model to replace again led..... | MIGUELTV |
| SEMP TCL | L43S3900FS | TV does not turn on LED ST BY blinking quickly, 12V power supply with only 6V. | Capacitors in the power supply primary: cw922 10uf /50v and cw920 22uf/50v, replace directly. | Eugênio | |
| SEMP TCL | 32S OU OUTROS MODELOS! | Blurred or inverted image after changing the card | Home key+062598+key with the three lines+ID of the original board, do this quickly and wait for it to restart | Rodrigo cofferi | Rodrigo cofferi |
| TCL | 55P725 | The backlight doesn't turn on, but the bus is fine. | AD602 diode shorted. (mbr3200) | To replace. | Persio (TVCompany) |
| SEMP TCL | 32S6500S | The TCL logo keeps restarting, the Android logo doesn't even appear | Update via pen drive | Cece eletrônica Brumadinho MG | |

| SEMP TCL | 32S6500S RT41PB-AG | TV with sound without image | Burned out led (1 led) | Replace of the complete, new bar kit and chain reduction. I replaced the two power supply resistors with just one whose value was 0.144ma. | Cesar762 |
| TCL | 50P6US | The logo appears and then turns orange with yellow bands that then go out. It appears to be the display but it is not. | Check on v-com r075, r076 and diodes d001, d002, d003, d004 | Jacinto Araújo | |
| TCL | 40S6500 | No image | Backlight with burnt out LEDs | Changing the LED strips and reducing the current by reducing the pulldown on pin 6 (iset) of UR01 (ob3365cvp), rr09 (12k) reduces the acceptable or rr08 (24k) reduces it considerably. ATTENTION: removing rr35 and rr36 does not reduce the current because they are 0Ω negative interconnection resistors according to the diagram available on this website. | ZENER Serviço Técnico |
| SEMP TCL | 43S615 | The TV turns on, the backlight turns on, the screen stays dark blue but no image appears. | Check if the 12v voltage on the ads501 smd diode is below 12v | Auterated 1m2Ω smd ar523 resistor. May God bless you all! | Eletrônica JM/Júlio |
| TCL | L32S4600 | LED burning even after reduction of 270k resistor modification tip | Inverter sending 77v | Remove the resistor and place a 680k one, 12 6s LEDs in total series: 72v, inverter is at a maximum of 71.2, protecting the new bar or replaced LEDs; | Valdecir Schena |
| SEMP TCL | 32S6500S | Totally inoperative total stop | Shorted wifi sign | Just replace | Eletrônica Rakelle |
| TCL | 32RS520 | Lower LED current | Remove rv112(6.8r) and rv113(2.2r) and replace it with a 2.7r resistor. consumption will decrease to approximately 60% of the original. | Romar |
