SEMP TOSHIBA	40L2400	When turning on the green LED, the logo appears and the standby LED turns red without sound or image.	Touched some black l leds. Even so, it continued to turn off, it was no longer the LEDs.	I replaced the burnt LEDs and resoldered the 3.3v regulator, it was cold soldered, resolved friends.	Marinho
SEMP TOSHIBA	PLACA U13 U13	It takes time to turn on and when it turns on the screen turns red and after about 10 seconds it starts to pulse, turning off and on and with some vertical retractions.	C862 ceramic open or burnt, c810 with low capacitance, q901, 903 and 905 shorted, open or with cold welding.	Replace and go do another one!	Jailson Lima
TOSHIBA	32L2400	Turns on with no sound and no image, backlight does not light up.	Screen conflicts with the main pci.	Unplug the TV from the socket, remove the flat cable that connects the screen to the PCI, turn on the TV. The backlight will come on, unplug the TV again and connect flat. When turning on the TV it worked perfectly.	REAL ELÉTRON CARVALHOS MG
SEMP TOSHIBA	LC3246WDA	Negative image	Image was pinkish in some colors	I re-recorded the 16-pin and bimba memory	jp eletronica
SEMP TOSHIBA	40L2400	This TV has already changed the LED bars 2 times this and 3 times	So as not to burn the LED on the bars, I did this procedure, I changed the resistor r765=2r2 smd to 4r7 smd, the 160v voltage drops to 150v, and the voltage of the LED bars was 94v 220ma drops to 88v 1.6ma, the TV worked It worked and it didn't come back, but my client has been in my workshop for 7 months, everything is ok.	Defect resolved	Andrei
TOSHIBA	TV2089 U14	I'm sound	Short between collector and emitter q612	Replace transistor q612 2sa1015 which is on a vertical plate, responsible for activating the bases of the mute transistors	Cunha
SEMP TOSHIBA	LE4050(B)FDA	Turns on, shows an image and then turns off the LEDs, the sound remains normal	It seems to be a defect on the inverter board, I changed the r52 on this p.c.i from 470k to 100k but it didn't solve it.	I searched the net and found how to disable the protection of the i.c ssl100sn, pin 02 put a 1k resistor to ground and if the defect persists put pin 8 a 1k resistor to ground too. follows as it is on the net: "I have a great day, I'm new and I just subscribed just to give another solution to the ssl100sn inverter circuit.. note that tsound is very little to say anything. information. well, the point is that searching one forum to another and after doing tests, I can find the integrated pin which is the olp and the ovp. The olp is located on pin 2 of the ssl100sn. in case the television turns on, it is heard and not seen) the ovp is located on pin 8 of the same integrated in the same way, to be able to cancel the protection, simply place a resistance of the same value (1kΩ) in the case. of having pin 2 grounded and continuing to fail. Well apparently that was all, for now, I would like to know your opinions, suggestions or also if you have already found the answer.	MIGUELTV
SEMP TOSHIBA	TV2134 SK11	The output of the 78040 vertical heats up excessively, after changing it it works for a while and then burns out again	Defective deflector	Replace deflector	Stanley01
TOSHIBA	TV2999	Nao liga, em stand by	D431 shorted killing 5v		INTERTEC ELETRONICA
TOSHIBA	TV1451 U18	Noise, power supply transformer noise.	D873 shorted	Replace	HNDRSN
SEMP TOSHIBA	DL3254AW	With audio.leds on.without video.on t.com,only 12v.smd capacitor cd25-10uf shorted.the voltage on this capacitor is 30v.	After changing this capacitor everything went back to normal. Electrolytic can be used.		gesuino
STI SEMP TOSHIBA	LE3973	It doesn't turn on, only the stand by LED lights up in green when it's correct and it turns red	Without 5v in regulator u8 as1117	Following the trail on the back of the board tsound are black diodes, in my case d1 was open.

TOSHIBA	TV2096 KMS U15	It doesn't just turn on standby and it doesn't oscillate	Measure the 9v at the emitter of the q430, if you don't have the 9v, replace the q430	In my case the transistor was the c1815, it was bad,	heliomaralmeida
TOSHIBA	1456M	Does not turn on, making noise at the power supply, LED lit normally and ticking very quickly and heating up the horizontal	Check deflection coil may be shorted	Replace the coil and run to the hug	Mauricio Eletrônica Santa Fé Cassilândia-MS
TOSHIBA	TV2987KMS	It turns on, it just flashes quickly or s.by	Replace c819 de22 / 100 v		Alécio Dal Pozzo
TOSHIBA	LC3242	Doesn't start	6 22mf capacitors, 1 100mf and 2 150mf open and altered	Just replace and run to the crowd	Wenceslau
TOSHIBA	2086	Reduced frame burning the horizontal	7n8 wide capacitor		HP ELETRONICA
TOSHIBA	TV2916LMS LEM8	TV turns on and off quickly with vertical closed	R311 open (in my case the TV had already come from another technician, the resistor was no longer in place)	I put one in and the TV is new (obs. resistor 3k-smd)	Antonio Carlos(Eletrônica Renascer
TOSHIBA	42XV500DA	Don't care at all!	Dead power supply	2.2 capacitor by 50v open. just replace	wert
TOSHIBA	TV 2999	It doesn't turn on and the power supply keeps ticking	Saida horizontal	Replace the same and Jesus loves you too...	tecnosat fabio
