TCL32S6500S
TV turns on, initializes and turns off, returning to stand by. Note: the LEDs were goodThe defect was in the LED controller circuit. voltage too high, arming protection. I changed the calculation of the return control resistors. and the tension dropped and the TV stayed on. OKJS Eletronica (Nilsinho Rodrigues)

Does not turn on, does not come out of standbyLocks up, doesn't turn on with the remote control or with the power button on the TVWith the TV unplugged, hold down the power button on the TV and plug it into the socket until the TV turns on, then reset factory settings with the remote control. reset password (0000)Eletrônica Valdecir

It has sound and no image!Burned out led bars.Replace the burnt bars or LEDs and to lower the voltage on the LEDs, remove the r634 3r resistorevandoviana
SEMP TCLL40D2900F
It has sound and no image!Burning LED bus. solution: reduce the voltage that was 85v on the LEDs by removing the two resistors (0r) next to the LED bus connector, the voltage dropped to 73v. replace the LED bus with a new one.evandoviana
