TOSHIBA	2934BSL SK91	TV turns on normally with a buzzing noise at the power supply as if it were a flaybek leak, sometimes loud and sometimes low	C633 is not shorted, it is cracked without capacitance	Replace c633 561k x 2kv	TIÃO SERRA
SEMP TOSHIBA	LC4058(C) F	Dark image (no brightness)	Power supply with ripple, c 878 220mf x16v, cw963 22mfx250v and cw961 22mf x250v, all sold out.	Replacing them.	CalixService
SEMP TOSHIBA	DL3277IA	When you press the power button, the TV turns on but the LEDs do not light up!	Zadbukh won	Replace the 27v zdp5 zener diode and the 1r rp77 and the TV will be working normally. God be praised!	Sinailson furtado
SEMP TOSHIBA	TV2098 U16	TV generates, reduced image with vertical lines below. 70v low power supply	D873 general purpose diode 1n4148 open		Ricardo silva (PA)
SEMP TOSHIBA	32L2400	Normal image, but with hoarse sound (as if the speaker was torn)	Capacitor c224 and c226 exhausted	Replace them, if the defect persists, replace c236, c211, c212, c217 (0.47μF smd capacitors)	Ev antunes
TOSHIBA	40L2400	It doesn't come out of standby, it just stays on the red LED	N807 3.3v defective, replace this regulator	As a precaution, also replace the n805 3.3v regulator	CARLOS ALBERTO
TOSHIBA	32L2400	Turn on standby, press power, write Toshiba on the screen and then return to standby	3v3 regulator on the main micro side was giving 3v0		Lucas
SEMP TOSHIBA	32L2400	Red LED on, does not turn on, voltages are as if the TV was working on the n807, it cannot have 3.3v on stand by	Replacing the ci dc/dc n801 which was bad	Swap n801	samuel leite
TOSHIBA	TV 2098 U16	Crazy, messy menus, inoperative volume or poor channels not tuning	Rewrite memory, I put it in virgin it didn't work correctly. ideal to write with correct data
TOSHIBA	TV 2098 U16	Time it turns on, time it doesn't turn on.	This solution seems obvious but it isn't.	Carry out complete resoldering. In this case the defect was some soldering in the oscillator, even though it didn't appear to be cold soldered. It was just a matter of resoldering it and the defect was resolved.
TOSHIBA	TV 2098 U16	Turn on STB LED and die	The TV turns on the LED stand when you press power, the LED turns off and no longer lights up, the secondary lights are reset	Defective fly beck. Just replace and receive????	Josimar
TOSHIBA	LE3973	When you plug it into the socket it goes to the green LED as normal and goes to the red LED.. pressing the power button several times goes to the red LED. When you press it again it goes to the green LED but it doesn't turn on..	The defect is very simple, you remove the eprom memory and replace it again and the TV will turn on normally... good luck		Diego de Lima Costa Nova Timboteua Pará
SEMP TOSHIBA	LC3255(A)WDA	It doesn't work, nor does standby light up. only the VD503 LED (red) on the main board lights up.	L803 open and c812 or 814 (smd 10ufx16v) shorted.	Replace capacitor with another equal one. replace l803 with another equal one or place a 0Ω resistor.	EvandoViana
SEMP TOSHIBA STI	DL3954	Disappear image after a few minutes. without image, with sound and backlight.	Defect in the display's tcom, specifically in the c.i cm501, after a while of use it cuts the voltage lx2 on pins 13-14.	Replace o c.i cm501.	Darci Denzer
SEMP TOSHIBA	DL3975 (A)	Turning off after 15 minutes	Replace u9 al1117-3,3v cp10 100mf 16v	Replace without measuring run hug	Luiz Macário
TOSHIBA	32L2400	TV doesn't turn on with red LED.	Shorted capacitor c 820, at the input of regulator n803, which produces a voltage of 1.5v.		MARCOS
SEMP TOSHIBA	LC3241W	Doesn't start.	Internally damaged relay and exhausted electrolytic capacitors	Replace the relay (12v x 250v) and the blue electrolytic capacitors (22μF x 35v and 50v)	Darci Denzer
TOSHIBA	2988LMS LEM8/FS6	TV had normal stand-by, when giving the command on the button to turn on it turned on with the vertical closed and it was noticed that the semp logo appeared and then it turned off	"d301" this diode is naughty, don't trust the multimeter reading when it comes to it...	Replace d301 without measuring.	Edfesom
TOSHIBA	32L2400	No image. the logo appeared and erased in 2 seconds. just keeping the audio.	To avoid return, I changed the current of the LED bars. I placed another resistor in series with the r765 (2r2 + 5r6) smd. the 91.2v voltage dropped to 86.2v, and the 271ma bar current dropped to 174ma.		Eletrônica R-Tec
