SEMP TOSHIBA	DL4845 DL4845I	The Toshiba symbol appears and turns off the screen	One of the modified LED buses	Replace complete bus - replace r766 from 5k1 to 10k (reduces circuit sensitivity, avoiding blinks) - remove six 2r7 resistors (r787, r790, r797, r794, r723, r782) this reduces the bus current, increasing the useful life of the LEDs	RUBERVAL SBC
TOSHIBA	TV 2157 FS FS2 LEM6	No image on rf av normal 33v /5v normal supply	Defective varicap		eletronica avn
TOSHIBA	40RV700FDA	Nothing turns on, with 3v3 and 5v present in the secondary power supply	Broken track (with oxidation) beneath the black paint on the power supply PCI		eletrofenix
TOSHIBA	MC852MP3	Turns on normally but no sound comes out	Ci sound amplifier	Replaced sound output stk433-060	ELETRONICA KLEIN
SEMP TOSHIBA	DL2970(B)W DL3270(B)W DL3970(B)F LE3274(A)W LE3974(A)F DL2971(B)W DL3271(B)W DL3971(B)F	When cold it works for a few minutes, after it heats up it turns off and the LED flashes quickly, alternating between green and red	Replace zd204 and zd205.		electronicssupplyparts - Gramado/RS
SEMP TOSHIBA	DL3271(B)W	When cold it works for a few minutes, after it heats up it turns off and the LED flashes quickly, alternating between green and red	Replace zd204 and zd205.		electronicssupplyparts - Gramado/RS
TOSHIBA	32L1800	After changing the LEDs. TV turns on normally and turns off	High voltage at the output	R795,r796,r797 remove them. stabilizes at 67.8v maximum peak 71	Msc
SEMP TOSHIBA	LE4056(A)F	Standby LED stays green and doesn't turn on	I changed the v802		Eletronica braz video
SEMP TOSHIBA	DL3977I (A)	Stand-by LED flashing green, does not turn on.	Voltage in the second 12v and 24 varying due to the diode with ba158 (dp9) is leaking. Just changed it and everything went back to normal.		Cezz@r Augusto
SEMP TOSHIBA	40	Tsound is no 12v and 24v only 5v	Nw901	Barter it	M.zidane
TOSHIBA	MS 7945MU	Does not turn on, no secondary voltage, only amplifier voltage (~50v)	Cold soldering on ic904 and ic905 (photocouplers)	Resolder ic904 and ic905, or replace if necessary. After this, 3.3v should appear on the secondary and the stand-by LED will light up	Bruno
SEMP TOSHIBA	LED DL3244(A)W	Don't care! only the red LED is on (STBY)	Ci n801 fr9889 broken!	Swap this ci for one of these (mp2307, ap3503, fr9889, mp1482) good luck	EVANDOVIANA
TOSHIBA	32L2400	Standby LED on, turns on, the logo appears and then returns to standby. Sometimes it doesn't even turn on.	N805 - 3.3v regulator	Replace the regulator.	Company Tronics
TOSHIBA	MS8030MU	Display off	R962 opened by: severe mailson	Replace.	Mailson severo
TOSHIBA	MS 8080 MUS	Display off	Open 4k7 resistor r 962	To replace	Emerson lima
TOSHIBA	MC855MUS	I don't read CDs, but tsound are books and everything, just don't read them	Defective optical unit can be replaced for the soh-ad3 which works properly, the soh-aav and soh-aan also work. in place of the original which is asoh-ad5
TOSHIBA	MC855MUS	No mute sound	Cold salad or defect in q 901 or something along those lines killing the negative 12 v	Resolder the transistor and check if the short in the zener diode hz902 is a 12 v zener, also check the capacitor ce913 if tsound is tension if not beforehand also check the components up to the transformer.
TOSHIBA	2090	Low supply +b around 75v, all the components that cause this defect were analyzed and they were all good...	Q432, smd transistor in the center of the board.	Do not replace, take off the board. (tec, edfersom varjota-ce)	Edfesom
TOSHIBA	LC4245	It doesn't turn on, nor does the STBY LED light up.	Capacitors cb 904,905, photo-couplers. in the case photo of the 5v power supply,	Replace mentioned components. I replaced them all to avoid future problems.	arock
