Make	Model	Symptom	Problem	Solution	By
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
TOSHIBA	1482	Lines at the top of the screen	C308 100ufx35v	Replace without measuring c308 100μFx35v	ASL ASSISTENCIA TÉCNICA TONINHO
TOSHIBA	1482	Turns on with noise in the power supply transformer	C877 47x50v c868 47x50v	Replace-them	ASL ASSISTENCIA TÉCNICA TONINHO
SEMP TOSHIBA	DL4053 (A)W	Does not turn on, nor does the stand by LED	Measure n805 middle pin with the negative housing, if it is shorted it was already a processor. If it's not shorted, tsound's a solution!	Replace nw910 and nw955 both are shorted primary and secondary power supply sector. I hope I helped!!	Maike Sorriso-MT
STI SEMP TOSHIBA	LE4050(B)FDA	Turn on the logo and turn off the backlight, sound is normal.	Tsound is a way to disable the protection of the ssl100sn ci, to do so, place a resistor (1k) from pin 2 to ground, if that doesn't help, also place a resistor (1k) from pin 8 to ground.		EC
SEMP TOSHIBA	DL3244	TV without image, but had backlight	Defect in the v-com, shorted capacitor was killing the 15v of the avdd,	Replace capacitor c25 with another of the same size	Tec. Daniel Schmidt
TOSHIBA	TV1451NAV U18	Vertical closed or semi open with lines and greenhouse c306 because the voltage rises to 25v and normal is 15v on it.	82k r306 open, bad contact or altered.		Hndrsn
TOSHIBA	2078FM CCP3400	White screen with no image, no control or keys	Remote control sensor kb01		Dalton
TOSHIBA	32EL933G 32AV933	Does not obey the command or the main keyboard	Corrupted firmware unsolder the eprom and program it, note programming it on site may give an error		jotira
