Make	Model	Symptom	Problem	Solution	By
TOSHIBA	40RV700FDA	No audio and normal image	My case was resoldering on the power supply board	Solve all power supply plate	Eletronica do Almiro
SEMP TOSHIBA	55L5400	Tsound are times when it turns on and tsound are times when the logo just appears and goes back to standby	N805 3.3 volt regulator was only at 3 volts and tsound were times when it was normal	Barter it	Central Eletrônica
TOSHIBA	2082 U8	LED turns on and off	Horizontal output shorted	Replace horizontal output bu2508dx	FÁBIO
SEMP TOSHIBA	LC3255 A WDA	The image is flashing, the backlight is flashing, if you notice the problem it will be due to the low 12v voltage.	In my case it was the v806 next to the 12v connector on the main board, it is npn and was open, just compare it with the ones next to it, they are the same reference.		fabiusmax
TOSHIBA	32HL86 PRINCIPAL E PLACA DE REGULADOR	Turns on and off, image turns on and off, does not turn on, turns off, relay hits and turns off	Change all 50v/10uf capacitors on the main board and a cap. from the 4-screw plate wsound tsound are 50v/10uf regulators	Replace all capacitors 10v/470μF, 50v/22μF, 50v/47μF, 50v/1μF next output, replace them all because they will be exhausted!!	Maike Sorriso-MT
TOSHIBA	2134 CSL	Image closed on the sides	Capacitor c635 330uf/50v with low capacitance	Replace c635	MARCONES DE ARARIPINA-PE
TOSHIBA	7980MUS	Intermittent sound disappearing	102 x 1kva cc902, close to the power supply str		Ogeid
SEMP TOSHIBA	LC4045 LC4045F	TV turns on without backlight. At first I thought it was an inverter board	Burnt out bulb causing backlight protection	Changing the lamps	Stefanon
TOSHIBA	DL3245	Does not turn on, stand by red on	Change 3.3v regulator (n805)		Antonio Augusto Batista
SEMP TOSHIBA	DL3244(A)	White screen without image with sound	Capacitor shorted on the screen board. watch the video https://youtu.be/wxlzi_djyxs		Eliel Batista
SEMP TOSHIBA	V2 48L2400	Backlight turns on and turns off in a few seconds	Deactivation of backlight protection. on the inverter part of the main board, go to ci n701 and place a 100k resistor from pin 10 to r786 (it's just below the ci). By doing this, backlight protection will be deactivated.		EC
TOSHIBA	TV2177(A)SL	Image disappearing at the top, with a distortion in the image, opening and closing, with sections disappearing. It didn't even appear to be vertical, because the distortion had no pattern and only parts of the image disappeared. and when it warmed up, it returned to normal.	D301. After spraying cooling spray on parts of the circuit to make the defect manifest itself, the diode ended up permanently damaged and the vertical closed.	When changing the diode, everything was fine. The defect no longer appeared, even though the TV was turned off for a few days.	Romildo Behrend
TOSHIBA	TV2959JFS FS8 LEM10	Low sound	Change capacitors c636, 637 without measuring. Both are close to the heat sink and over time, it is normal for them to dry out.		jr_TEC
TOSHIBA	TV2999JMSLEM6	Screen with excessive contrasts	R226 open	Replace	Paraense
SOM TOSHIBA	MS-7760MUS	This sound would turn on, and then return to standby mode, then I saw that one of the audio output MOSFETs had a short circuit, so I replaced it, and it stopped turning off. But I noticed that the l803 coil was getting very hot, to the point wsound smoke was coming out, so I removed all the wire from it, replaced it with a new one, and it still had the same defect. The solution I found was to replace it with one of these, which is on the horizontal tube TV circuit. and I also replaced the r818, 10r. and the problem is over.	Replacement of coil l803 and r818 and also one of the power supply MOSFETs in short position q806. fqpf16n15		MARCONES DE ARARIPINA-PE
SEMP TOSHIBA	TV2959JFS LEM10	Turns on and off, then the LED goes out	Open 220k resistor r851	Replace the same	Ofina dos eletrônicos
TOSHIBA	2921HFS LEM8	Does not turn on LED lights up then goes out	Capacitor 819 de 10mfx50v		ELETRÔNICA DO GILVAN
SEMP TOSHIBA	40L2400	Without any sign of life	No 1.15v voltage on the l801 coil even with pin 7 of the n801 with 4v.	Replace n801 and the TV works again.	Andre crisópolis
TOSHIBA	32L2400 SLV1	TV turns on, green LED lights up, tsound is sound but the backlight doesn't turn on.	Good led bars. cause: v751 and l701		Eletrônica Pauly
TOSHIBA STI	LE 3252I KPS+L070	It doesn't have 6v sometimes it does, if you remove the cable from the mains it doesn't have it anymore, taking it out and putting it back in several times comes	At the power supply in the primary replace the smd 6755 (cb904)		Eletrônica Ômega
