Make	Model	Symptom	Problem	Solution	By
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
TOSHIBA	52XV550	I'm sound	Earphone oxidation	Cleaning it or replacing it	wellington h diniz
TOSHIBA	TV2052(O)AV	Turns on with a line at the top, closing when the volume increases	It was r861		NANDO ELETRONICO
TOSHIBA	TV2052(O)AV	Turns on and off with part of the upper screen closing and power supply with 40v at mas +b	It was the photocoupler and the q856		NANDO ELETRONICO
TOSHIBA	TV2157MF-U 17	Turns on with a line at the top, closing when the volume increases	Era c884 160v 220uf		NANDO ELETRONICO
SEMP TOSHIBA	DL3944	Istandby changes to green but does not turn on low 12 power supply inverter circuit	An analysis of the defect was carried out and we found a voltage of 12 volts in standby 7.5 volts	Transistor vw953 open open resolved the issue	ELETRONICA SALES. NATAL RN
SEMP TOSHIBA	LE2445[A]	Turns on then turns off to stand-by as soon as you apply the hdmi cable with signal	After checking the processor for heating, I reballed it and cleaned it with alcohol.	Note: HDMI didn't work but the AV was fine!!	Medeiros Eletrônica/Barbacena MG
