TOSHIBA	MS8012MU	No sound, no audio	R937 on pci power supply value 1k	Just replace and run for the hug	Vander CDs de Quixadá CE
SEMPTOSHIBA	TV1484FAV U11	It arrived on my bench with a burnt flyback and open r430, altered r227 and dry c889, replaced components. TV turned on with a blue screen and the image closed, found c305 altered and d901 shorted without characters	R430 r227 c889 c305 d901 flyback	All components replaced TV turned on perfectly	Eletrônica Lima pb
TOSHIBA	LC3246 W	Does not turn on the lamps	Model in which the power supply board is integrated with an inverter, if the 12v voltages and the on off pulse are normal, changing the circuit n701 ref.uba2072 in my case did the trick, I got it from another board.		Alberi F S
TOSHIBA	40L5400/48L5400/55L5400	Nothing turns on, no stand by LED, 5v stand by power supply absent,	On the board next to the processor tsound is ic code n806. fr9889 (dc/dc converter) had voltage on terminal 2 (input) that comes from the main power supply and did not have 5v on terminal 3 (output)	Replacing the aforementioned ic n 806 only solves the problem.	Assolini BR
TOSHIBA	MS7945	The panel doesn't light up and the sound is noisy	The blacked-out panel was resolved by replacing r962 at the power supply, and the sound defect was missing a negative supply in the IC402 pre-amplifier IC, transistor at the power supply q953 c3205 toasted	After replacing the components, the solution was resolved.	Protec eletronica
SEMP TOSHIBA	LE3250	How to arm the fountain	A 100r resistor from 5v to the ps_on		EletroClaudioPE
TOSHIBA	40RV800	Sound failing, or no sound	Abnormal pfc circuit, 300v on 220v network	Altered reference voltage resistors, connected to pin 1 of the pfc driver ci	davi.sls
SEMP TOSHIBA	32LH86	Hissing sound, even without audio signal	C629 and c685 both close to the c.i. audio system ta2024c, also replace r620 and r623 10r		Testoni Junior
SEMP TOSHIBA	32LH86	Turns on, screen lights up but turns off in approximately 15 seconds	Chap. elect. CG06, CG07, CG14,CG15,CG20,CG22,CG24, CG35, all 10x50v and C629 and C685 1x50V on the main board and CE87 10x50V on the intermediate board		Testoni Junior
SEMP TOSHIBA	XB1207 MU	Doesn't start	Check pin 7, if it is low (8v +/-) change c803, if tsound is no voltage change r805.		Carlossbs
SEMP TOSHIBA	LC4046FDA	Without image, with sound.	I identified the open fuse f102 on the inverter board and a short to ground caused by some component on the right part of the board. By pure luck, the first component I removed for measurement was the one causing the problem. The smd 125v/7a fuse (f102) and the ci 4614b (q310) were replaced and everything worked again.		Bertinetti
TOSHIBA	DL3975	It doesn't turn on, it just keeps flashing green LED	Replace dp 9		jcgiantomaso
TOSHIBA	32L1800	Half luminance	Ss5dc diode at position 771	Changing it or ss36 works perfectly	Airton Filgueira
TOSHIBA	MS7980MUS	Period	C902	C 902 is the coil
SEMP TOSHIBA	TV14 VARIOS	No channel 3 and av i.e. blocked channels (when I tried to put them on they didn't appear, they were blocked)	Enter the menu (normal) and select the option, block av/tv (something like that), go to password and press "s" on the control several times, until it unlocks.
SEMP TOSHIBA	2934 SK91	It doesn't turn on, just the relay hits	TV hits the relay, LED stays off	-trazesto q604 -trazesto q606 capacitor c311	glaydysom rio branco ac
SEMP TOSHIBA	32L2400 40L2400	Does not turn on, LED is off	No. 07	Vdw904 measuring short, but it's the ci nw907's fault	Adrian (Chapadão do Céu Goiás)
TOSHIBA	TV1415NM U18	The television arrived with the pwm of the power supply shorted and the primary completely detonated, after removing the defect in the primary, the television arrived with voltage in the secondary, but it made a noise in the power supply and the voltage fluctuated wildly, a detail that when the +b of the fly was turned off -back the voltage stabilized at 64 v at +b.	Deflector coil with horizontal bearing changed from 5Ω to 10Ω	Replace the deflector or replace the entire tube. (edfesom ;)	Edfesom
TOSHIBA	U17	It heats up horizontally until it burns out and the power supply dies, the LED goes out	Coil will reflect short	Changing the deflector	FRANCISCOFERREIRA
TOSHIBA	TV2085(F) U11	It takes time to turn on, when it turns on vertically closed at the top and without tuning the channel	C 889 470mf x 35v		NEW PEK ELETRÔNICA
