SEMP TOSHIBA	DL4844(A)F -	League. STBY LED lights up, does not accept C.R. commands. and keyboard.	N806 shorted and n804 altered, en pin less than 2.4v, normal 3.1v or more, depends on the circuit.	The components n806 and n804 were replaced.	Cesar762
SEMP TOSHIBA	40L5400	It turns on normally, the logo appears and returns to standby.	Several LEDs burned out, the complete set was replaced. problem persisted.	Defect in the 3.3v regulator 1117-33 silkscreen in this version n808 marking 2.9v. replacement made and problem resolved
SEMP TOSHIBA	40L5400	Does not turn on, does not oscillate primary power supply.	Short circuit in the 6v8 smd zener diode in the primary power supply position VDW904. If the TV still doesn't turn on, also replace the CI PWM Fan6755W		rafaelmoraes99
SEMP TOSHIBA	DL3244(A)W	Does not turn on, stand-by turns green but does not start. without +b 12v	Transistor npn smd vw971 (2n3904)	Transistor responsible for powering the power supply, replace it with any NPN 40v 500mW.	Beto Eletrônica
TOSHIBA	2051U18 U18	Low sound	Cause speaker	Speaker replacement	Cícero Santos
TOSHIBA	U19 U19	When you plug the TV into the socket it wobbles and makes a ticking noise very quickly.	The defect was the c448, I replaced it and the TV works again		AssisTec - Manari-PE
TOSHIBA	1451 U19	Horizontal burning	R512	Replace r512	Cícero Santos
TOSHIBA	42XV600 0000	TV inoperative without stand-by	Strz2589 e r851=AR,AR	Replaced, slept....	Jhone eletronica
TOSHIBA	TV2084 U13	On off on	Unknown		José Erismar Rocha
SEMP TOSHIBA	48L2490	TV works for a while, makes a noise through the speakers, scrambles the image and then turns off, remaining stuck in standby	Replace the two ci fr9889 position n801,n802		William
TOSHIBA	TV2977(A)SL	Standby LED is on and does not turn on or start.	Driver transistor q402 (2sc2482) shorted	After changing the TV ok.	George Pontes
SEMPTOSHIBA	2134 2134	Knocks relay but doesn't start	Make sure you haven't put the headphone jack in the right place, because you might be putting it in the memory location and it keeps shorting out the data + and data -, so it won't turn on.		Eduardovaz_
TOSHIBA	TV2177(A)SL	Rainbow effect	Ic301 vertical shorted, replace the same, tda4865aj		Seen store
TOSHIBA	TV2177(A)SL	The TV would turn the LED on and off, hit the relay as if to turn it on and the LED would go out.	R604 changed, replace the same		Seen store
SEMP TOSHIBA	2159(O)FS U19	No contrast	R227 and r226 open	Replace them	Daniel
SEMP TOSHIBA	DL4061(A)F DL4061	It turns on right away, turns off and stays in this loop	Corrupted data	Update software (insert pen drive, hold down menu key and plug in)	Junior - Tecnoprom
TOSHIBA	2134 BSL OU CSL	Heating and burning vertical output because +b is above 114v	Replace the 220k r633 which must be changed for a 200k one	The 16v and -16v are above this voltage, put a 200k resistor on r633	Fábio
TOSHIBA	BSL OU CLS	Heating and burning vertical output because +b is above 114v	220k r633 changed	The 16v and -16v are above this voltage, put a 200k resistor on r633	Fábio
SEMP TOSHIBA	LC3246WDA	TV works normally for 1 hour, turns off lamps (or turns it off and on again)	Invert board (but the power supply also does it)	If, when plugging the TV into the socket, the power LED turns yellow then red, the board inverts (just replace it) if it turns green and then red, the power supply board (turns off the protection system)	Eletrônica Manauara
SEMP TOSHIBA	DL4061	LEDs were broken in some rulers. After changing the complete kit, the TV would sometimes fail to turn on or when it turned on, all the lights would light up, but after a few seconds it would randomly turn off.	I used the tip from my friend "juci" burned out leds reduce the voltage of the leds remove r13 (150k) and replace r 12 (6k8) and put 10k	I replaced the circuit as my friend Juci suggested and the TV no longer turned off. It was acting as protection on the LED drive circuit.	MIGUELTV
