Make	Model	Symptom	Problem	Solution	By
SEMP TOSHIBA	TV1470E	When it turns on, the characters appear but soon after it starts, it runs away and disappears.	Qa09 (c1815y) with leakage from the collector to the emitter.	Replace for the new one.	toinho eletron
TOSHIBA	TV2959JFS FS-8	Works normally but without sound and has audio and all normal output and mute voltages	Convert to eeprom (memory)		samuel leite
TOSHIBA	2916 LEM9	High screen and green canvas	Shorted tube in green color	I replaced the tube	DANGELO RODRIGUES
TOSHIBA	TV2999LMS LEM 8	When it turns on, the LED turns on and off, the power supply goes to zero.	C819 47mfx50v, I also changed c879 10mfx50v	Once the replacements were made, it was ok.	(Léo Natal RN) (This email address is being protected from spambots. You need JavaScript enabled to view it.)
TOSHIBA	LEM7	Does not turn on and makes a hissing sound	Horizontal output shorted q404	Replace the output and remove the l441 coil and resolder the wires to avoid burning again	eletronica fernandes-to
TOSHIBA STI	M1931	Blurred image, increasing brightness gives shadow to the image	Dry electrolytic capacitors	C11 and c12 of 220μF/25v, c22 of 10μF/50v on the inverter and c217 of 220μF/25v on the power supply	eletronica fernandes-to
SEMP TOSHIBA	42HL57	TV without sound and LED image activates Note: after several attempts, the TV returns to working normally. When turned off for a long period of time, the defect appears again.	C862 2.2mf changed		jorge luiz mantini
TOSHIBA	TV2999 LEM7	TV with vertical closed turning off 8817	Well guys, this defect was a tough nut to crack, I put in a brand new vertical, nothing, check all the resistors, nothing, I changed the yoke, nothing, well the defect was the d301 diode, which was altered, I tested the multimeter, it looked good, but when measuring with it on the board, it was open	D301 replace close to vertical	marcos melo cascavel ceara
TOSHIBA	TV2098 U16	No sound takes time to connect	Audio power	C887(100μFx50v) replace without measuring	CABEÇÃO NATAL
TOSHIBA	TV2096KMS U15	Dark screen with normal 15cm side stripe.	R447 open, flyback pin 10.		nedson
LCD SEMP TOSHIBA	LC 15/2010Z	The power supply does not start	Check on the PCI main stage of the power supply if the electrolytic capacitor c356 is altered or has unsoldered terminals.	Capacitor/ c356	xmichaelx
LCD SEMP TOSHIBA	LC 2010Z	The device turns on, the display lights up and then turns off spontaneously, activating the protection.	C30/ c31/ c32, approximate voltage value across the capacitors, c30 15v/ c31 19v/ c32 19v.	Check the inverter circuit, in the protection stage, if the capacitors are shorted; c30/ c31 /c32 / 100kpf. To turn off the protection, it short-circuits the collector and emitter of transistor q9, and damages whether the device works normally.	xmichaelx
LCD SEMP TOSHIBA	LC 15/2010Z	Display without video (all white screen) and normal audio.	Shameless/D40/Saah0/Saats	When they noticed on LCD televisions models LC 15/2010z, display system without video, completely white screen and normal audio, located on the main PCI a/d. check: u27/d40/c370/c369, detected most frequently (d40) with leak. if the u27 regulator voltage was below 9vdc: completely white LCD screen.	xmichaelx
TOSHIBA	21V33E3	Stand by always flashes and the TV doesn't start	Resistance r 540 open	I replaced the resistance r 540 of 100 men and it is great	antonio costa
TOSHIBA	TV 2158NFS U18	Does not turn on, LED is off	Poor contact on the power switch pin "cold welding"	Resolder and if necessary resolder the board components to avoid new defects	ELETRONICA CARLOS
TOSHIBA	1451NAV U18	No contrast, brightness and very dark colors.	The defect was the ceramic capacitor c 902 on the tube plate (102 k / 2000v).	I resoldered the entire tube plate, but that didn't solve the problem. measure the voltages on the transistor collectors, they were normal. the voltage on g2 was low, the capacitor was killing the voltage on g2. replace it and the TV returns to normal.	Júnior/Maceió-Al
SEMP TOSHIBA	TV 14 OU 2091 U14R	When turning on the TV, the LED lights up for approximately 5 seconds and then turns off. After this procedure once, it no longer lights up, only after a few minutes. I tested and replaced all c3209, fly back, power supply capacitors, no solution.	I only solved the problem by replacing the stv9302 vertical output. obs. "I used tda9302 and it worked perfectly."		Carlos Guerra
TOSHIBA	U14-R CCP3400		LED lights up but does not turn on, power supply is normal. Does not oscillate horizontally		hilderaldo
TOSHIBA	TV2134-BSL	TV with vertical closed and turning off. also with reduced frame.	Diode d 306 replace without testing +16v		DEBIQUE
TOSHIBA	TV 2089 U.14	Popping fly-back	Q.421.7805/ q.422..2sc.2655/ r.422.2k2.smd		Zezinho DE NATAL
