TCL TOSHIBA	40S4700FS	Burnt voltage regulators next to the LVDS cable plug on the main board, Q900, Q901.	Oscillations in the electrical power grid apparently.	Replace voltage regulators next to the LVDS cable plug on the main board, Q900, Q901.	Adriel SS
TCL TOSHIBA	40S4700FS	No image	Burnt voltage regulators next to the LVDS cable plug on the main board, Q900, Q901.	Replace voltage regulators next to the LVDS cable plug on the main board, Q900, Q901.	Adriel SS
TOSHIBA	2159OFS-U19	Closed vertical (white line in the center of the screen), but with sound	Ci responsible for the vertical (q301), oscilloscope board transistor (rgb) and resistor r442... getting very hot	Due to the short generated by the ci (q301), excessive heating occurs in the other components... replace it and problem solved! Note: case
SEMP TOSHIBA STI	DL3270(A)W	Does not turn on, LED does not light up	Does not provide 12v, 12v power supply with 2.6v	Transistor q305 2x smd with leakage, and the same transistor 1p	Center som
TOSHIBA	40L2400	Screen with some lines in the background	Defective tcon board	One resolved it with cleaning. Another resolved it by changing the tcon.	Elenilson lua nova
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.
