Make	Model	Symptom	Problem	Solution	By
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
SEMP TOSHIBA	LE4056(A)F	Does not turn on; When connected to the network, the green LED lights up and goes out	Corrupted flash memory	Re-record the flash	Julian C Braga (Hitech)
SEMP TOSHIBA	LC4241W	Does not turn on, without voltage of 5v and so on, does not hit the relay	Capacitors c866, c842, c843 all 22uf/50v open	Touch the same	Julian C Braga (Hitech)
SEMP TOSHIBA	LC3246WDA	Does not turn on, LED changes from red to green, but no image	Power supply without 12v and 24v	Check resistors around the IC of the NCP1653A PFC, to facilitate identification, measure the voltage above each one, equal resistors in series must show the same voltage drop, so an altered resistor is discovered, most of the time it is the glue under the resistor , you have to remove and scrape the glue!	Lucas
TOSHIBA	U15 U15	LED on but not turning on, voltage+b 118v, heating up q430	Capacitor c419 without capacitance (plays the role of the horizontal driver transformer on TVs that use it)	After replacing the capacitor everything went back to normal	Lucas
TOSHIBA	TV2959	Doesn't tune, just drizzling, 32v missing on the tuner pin	Leaky diode d101		Marcondes Ohm Eletrônica Jaicós PI
SEMP TOSHIBA	TV2959	Low sound	2 47/25v capacitors next to the sound output		Marcondes Ohm Eletrônica Jaicós PI
SEMP TOSHIBA	42RV700FDA	Screen lit, but washed.	An open dc/dc coil on the t-con	Re-soldering coil terminals	Jump Eletrônica
SEMP TOSHIBA	TV2083 FAV	TV closed top of screen. It opens as the TV heats up.	C 305 1mf x 50v	Just replace and run for the hug.	NEW PEK ELETRÔNICA
SEMP TOSHIBA	TV2134	Red tv with retrace lines with normal sound	15k red pin resistor heating up tube socket defect		Lincam Bezerra
SEMP TOSHIBA	LC3246WDA KK	Green LED on does not turn on. does not release screen.	Capacitor c805 100uf/16v shorted.	Replace ok	Wil
SEMP TOSHIBA	DL3271	Screen with vertical scratches and screen half with scratches and the other half working.	Tsound were two televisions: the TCOM was changed on both, and the defect remained exactly as it was. screen defect.	Were returned due to lack of parts to buy (the screen in this case)	margutek.bva
TOSHIBA	40L2400	Changed LEDs burned out, turned on and stayed on for approximately 57 seconds	The tv had the usb input selected	Replace input before it turns off and the TV remains normal without turning off	PAIM ELETRONICA
