Brand | Model | Fault | Detailed Problem | Solution | By |
---|---|---|---|---|---|
SEMP/TCL | 55K1US | Dark screen only sound | Led bars | Changing LED bar kit LED voltage was 118v. when the right one would be 108v each led is 3v I removed r772, r773, r789 the voltage dropped to 106v | Valerio |
SEMP/TCL | 55K1US | Dark screen only sound | Led bars | Changing LED bar kit LED voltage was 118v | Valerio |
SEMP TCL | L49S4900FS L49S4900FS | Television does not turn on completely inoperative does not light stand by led fuse burnt out due to shorted regulator | 2 regulator 50wn1k0 shorted replace with tk7p60w | If the TV had a blown fuse, check these regulators on the board, position QW3 and QW4. After the replace, the TV started working normally again. | Eletronica15 |
TCL | L48S4700FS | Turns on and alternates colors (white, green, blue, red, etc.) | Clean all ribbon cables | Amarildo Callai | |
TCL | L55S4900FS | Power supply burned out and the new one only works on 220v | I bought a new one on Aliexpress but it only works on 220v | I solved the problem by changing the r431 resistor to a 56kΩ one (resistor code 563) | R10 Informática E Eletrônica |
TCL | L55S4900FS | LEDs burned out | Change the complete LED kit and change the power supply by removing 2x 15Ω resistors reference R623 and R625 to lower the voltage and not burn any more LEDs | R10 Informática E Eletrônica | |
TCL | 65P65US | Does not turn on, customer complained that he heard a pop. After opening, several broken and burned components were found on the power supply board. | Cause: c414(220pf 1kv) or c302(220pf 1kv). It is recommended to apply 2kv. | Sequence of components that fail: c414(220pf), c302(220pf), u401(ld5537 or 8537t or 8535), r403(330r), r402(330r), r419(68r), r420(2r7), r421(22r), d401=mc2838 (50v 300ma). | EC |
TCL | 49U7800 | Changing the backlight and reducing the power supply | Continuing the previous tip; to reduce the backlight power supply directly on the power supply board, replace the smd resistor r619 (47k) with a 10k resistor. After that you will see a reduction of around 5v in each of the two backlight power outputs. | EC | |
TCL | 49U7800 | Backlight defect; method of reducing power directly on the power supply board; | After changing the backlight, reduce the backlight power supply. | EC | |
TCL | L40S4900FS | LED burning | Power supply changed with extra voltage | Remove resistor r341 12k and r314 24k (underneath pin 2 to ground) insert 1 of 15k | JUNIOR PORTALTEC ELETRONICA CATALAO |
TCL | L32B3303 | When turned on, "initializing" appears and doesn't go through, nothing else turns on | Defective 25q64 memory | Read 25q64 and write to another memory | Edson SP |
TCL | L40S4900FS | Restarting | Update software | It was disconnecting when using YouTube and Netflix. follow steps to update the system using the tcl guide | Axcell assistência |
TCL | L32S4900S | Led current deduction | Modify resistor that is between gnd and pin 6 of the ub801, thus reducing it from 81.1v to 76.6v | Remove the 270k resistor and install a 360k one, | Paial.eletros |
TCL | 32S6500S | Reduce LED current | Remove the rr08 from the circuit | naelson silva gravata pe | |
TCL | 50P6US | TCL appears and goes off, leaving vertical yellow or orange stripes on the screen, it seems like it is a faulty display. | Shorted vcon protection diodes | I followed the tips from previous friends and it worked. (thank you!! (check the 100r resistors (r075 and r086) of the vcon on both sides, if they are replaced it means that the protection diodes (d001 and d002 - left side) and (d003 and d004 - right side) are shorted , remove diodes and leave without and replace resistors) | CDS_DIAS / LED TECH |
TCL | 55EP660 | Very bright screen | Replace eeprom | ERP-ASSIST | |
TCL | L32S4900 | No image, sound ok | Ceramic capacitor shorted on the screen board | Matias ERP | |
CONVERSOR SEMP TCL | DC-2008-H | The LED turned on, but tsound was no image | I removed the vga heatsink and heated it with a hairdryer for about 5 minutes | And it worked normally again, these factory solders have little alloy, so over time they lose their alloy, mad just heat it up again and it's gone. | Kohlmann |
SEMP TCL | DC-2008-H | The LED turned on but tsound was no image | It was the VGA with cold soldering, I removed the heatsink and gave it heat | With the hairdryer for about 5 minutes and it worked normally again | Kohlmann |
TCL | 32S6500S | Totally inoperative | Capacitor smd cdd1 de 10u | Replace the same and run for the hug | Eletronica kerkhoven |
