Make	Model	Symptom	Problem	Solution	By
TOSHIBA	32RV700	I'm sound	Q8110, d8110 4v3, c8110 100k and c8113 100k on the power supply board		Ademar
TOSHIBA	TV2958GFS	Turns on the logo appears and turns off	Cold solder on the transistor.	Transistor qb20.	Eletrônica ideal
SEMP TOSHIBA	DL3975I	TV just keeps blinking green LED	12v power supply pulsing	Replace the dp9 ba158 diode. Tsound's no point in testing, I put an sk4f1/10 in and it worked fine.	Alexandre Oliveira
SEMP TOSHIBA	DL4077I	TV just keeps blinking green LED	12v power supply pulsing	Replace the dp9 ba158 diode. Tsound's no point in testing, I put an sk4f1/10 in and it worked fine.	Alexandre Oliveira
SEMP TOSHIBA	14415N U18	Blinking led	C865 10 n shorted	Changing is running to dim dim	Francisco de Jesus Conceição l
TOSHIBA	40L2500	Bus LEDs flash but do not light up, new or used buses.	Faulty LED driver circuit or dim control.	Next to the oz9902, add a 10k parallel smd resistor on top of the capacitor (c718 smd), deactivating protection.	RNSPTEC
TOSHIBA	48L2400	It only stays on standby, red LED is on but does not turn on	Changing the 3.3 volt SMD regulator, when measured it was only 3 volts and tsound was 3.3 on another 2 regulators that could not have any voltage with the device on standby, changing the regulator close to the processor and resolved.		xande
TOSHIBA	40RV700FDA	Doesn't start at all	Shorted fuse transistors on the board reverses. tra. 7n50u and fus.802. tsound was a broken track on jumper line 854	Replace these components and good luck	flavio
TOSHIBA	40RV700	Doesn't start at all	Shorted fuse transistors on the board reverses. tra. 7n50u and fus.802. tsound was a broken track on jumper line 854	Replace these components and good luck	flavio
TOSHIBA	TV2923	Very low sound	C636 e c637 de 47ufx25v
SEMP TOSHIBA LED	DL3277I(A)	Burning the LEDs	Current on the LEDs very high 83v! the expected is 72v.	Replace the LEDs (all) or the LED bars (all) and replace the values of rp48, rp53, rp76, rp79 all from 0.47Ω to 0.50r, 2r2, 3r, 4r7. the voltage should drop to approximately 72v.	EVANDOVIANA
TOSHIBA	1488 U14	Reduced screen	Probable cause was loose r873 smd		Marcio eletronica sao carlos
TOSHIBA	1488 U14	Reduced frame and dark screen	Probable cause was loose r873 smd	I got one on the u14 board and that was it.	Marcio eletronica sao carlos
SEMP TOSHIBA	LE1958(A)	Off without voltage on the secondary	VDW951 and VDW961 shorted, burned the rw920 (2r7), the zener VDW921 (18V), transistor VW921 (1AM or 1F)	Check them all and reset.	GDP2
SEMP TOSHIBA	DL3261	Does not turn on, stand-by light is on but does not follow commands	Change regulator 1.5 volts position u174		TORMES
TOSHIBA	TV 2159	LED off, dead, nothing works	R860 near the voltage doubler cap behind it and plonto		eletronica publison natal rgn
TOSHIBA	L32D2900	Burning LED bus.	Voltage above normal at the backlight power supply output	Replace the resistors r795 and 797 (0Ω) to 1Ω and remove r796, all next to u770.	Samuel Silva
SEMP TOSHIBA	DL3277	Turns on and in 2 seconds turns off the backlight	LED changed on the bar	Do a test by placing a 1k resistor on the bar pins in position k a	Adrian Chapadão do Céu Goiás
SEMP TOSHIBA	LC3241W	Does not turn on, nor does the LED light up	Capacitors c-877/847/842/864/865/843/835
TOSHIBA	2134	Auto buzzing at the power supply. everything good, almost everything, in truth.	Capacitor de 47 160v	The capacimeter was good, as it showed 49μF. I replaced it and the power supply was silenced.
