Tcl Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| TCL | 32S5300 | LED connector in the 50 Volt range | DR01 Diode Replacement | Osmar | |
| TCL | L55L4900FS | Reduce LED current | Not set R623, R624, R625, R626, R627, R628. | Remove 2 150Ω resistors and 560Ω resistor. | Mau3000 |
| TCL | L43S4900FS NT563 | Lower the voltage on the LEDs to increase the useful life of the LEDs. | Remove 2 270k smd resistors that are in parallel RB812 and RB813 and place a 150k resistor in their place. | After the replace, the maximum voltage per LED bank must remain at 72v, which is ideal for this model. | rafaelmoraes99 |
| SEMP TCL | 32R5500 | Reduction of LED current | High voltage in LEDs | Remove resistor RV113, 2r2 | Beto |
| TCL | 43S615 | Locked on logo | Download program to pendrive | Put the TV on and let the rest of this plague of bad TV solve the virus, I believe, bad TV Good luck | Eletrônica publisom RN |
| TCL | 43S615 | Doesn't turn on | Water from rain near fransformer, transistor near fail. | Replace transistor | Eletrônica publisom RN |
| 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 |
| 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 | |
| TCL | L40S4700FS | Restarting | System nand memory corrupted ->download this file: https://electronica-pt.com/su/1c/ external link. | Indicated pendrive settings: 1. pendrive formatting: fat32 (default) 2. extract the downloaded file to locate the update 3. the pen-drive can only contain the update. Before starting the procedure, check if tsound is only the update file. To carry out the software update procedure, follow the steps below: place the update file on the pen drive; disconnect the TV from electricity; connect pen-drive to USB port; press the power button on the television and keep it pressed for approximately 10 seconds; plug the TV into the socket with your finger still pressed and wait until the update screen (loading bar) appears; After this screen appears, you can release the power key. | Allan da Macro |
| TCL | 65P65US | LED current reduction | Remove r628 and r629 which are connected to pin 2 of the ci, and place 01 of 47k in their place, note: the 2 resistors are in parallel | reginaldo moronte,eletronica junior caldas novas | |
| TCL | 65P735 | Remove r628 and r629 which are connected to pin 2 of the ci, and place 01 of 47k in their place, note: the 2 resistors are in parallel, remembering that the 55p65us model can do the same procedure | |||
| TCL | L55S4900FS | LED current reduction | Retire o resistor r623,coloque r624 560,r628 150,r627 150,retire r625,retire r626,retire j12 e coloque resistor 560 | By doing this it will decrease by approximately 4 volts per side, this is enough to not heat up too much | reginaldo moronte,eletronica junior caldas novas |
| SEMP TCL | 49SK6000 | Turns on normally but the LEDs from the bad LED print do not light up | Pdin pin in power socket burned out | RJ ELETRONICA | |
| SEMP TCL | 32S5300 | Voltage of the LEDs at 67v, causing premature burning. | Replace the rr08 of 2r20 for one of 7r5 and the rr09 of 3r30 for one of 5r10. | By exchanging the rr08 and rr09 the voltage from 67v dropped to 60v, as each LED works between 6 and 6.4v the voltage remained within normal limits for the component. | Gabriel G.T. |
| SEMP TCL | L39S3900 | Doesn't start | Broken fountain | Ci power supply driver is em8635, the equivalent is ld7537 | Davi.sls |
| TCL | 65P735 | No image | It looked like a burnt out LED bar | Shorted diode on the board that rectifies the LED current (just replace it with another equivalent) | reginaldo moronte,eletronica junior caldas novas |
| TCL | 32S6500S | Dead TV does not turn on standby but with some voltages fluctuating | Power supply, check if tsound is pfc voltage around 300v, measure capacitor cu05 to make sure the oscillator is being powered by 5 to 6v, if everything is measuring, check voltage on top of capacitor cr01, it must be 12v! If you have 8, 9v, just change TL431, position US51, close to the photocoupler! and run for the hug! | Rafael Sena | |
| SEMP TCL | 40S615 | TCL appears and turns off | AD603 diode shorted | Diode near the LED connector shorted, just replace "mbr3200" | WELL |
| TCL | L32S4700S | Decrease the voltage of the LEDs | R 797 (0r) r792 (0r) remove and insert one of 10r each | Every day I thank God for another day of life. | Eletrônica Bastos Elísio Medrado BA |
| TCL | L32S4700S | Decrease the voltage of the LEDs | R 797 (0r) r792 (0r) remove and insert one of 10r each | Every day I thank God for another day of life. | Eletrônica Bastos Elísio Medrado BA |
