Make	Model	Symptom	Problem	Solution	By
TOSHIBA	40L2500	When plugging in, the standby LED flashes once and turns off, the TV does not turn on	N807 defective, pwm is going out but takes a few milliseconds to work	Replace n807 - ci fr9889 (5v_stb), then the TV works again	Malinkiman
SEMP TOSHIBA	DL3271(B)W	Blinking LED does not turn on	Diodo dp9	Replace without measuring in my case it was him	EletroClaudiope
SEMP TOSHIBA	DL3254(A)W	Does not turn on, no standby - primary voltage only	Ci nw907, r913, r914, cw920, cw923	Tsound was voltage from the primary but it did not oscillate, I replaced the capacitors, checked the 2 open resistors, made the replace and still it did not oscillate, so by changing the ci it started working again.	JADISON - ELETRÔNICA 2001
TOSHIBA	32L1600	Normal menu works for about 30 seconds then menu locks and turns off.	Update via pendrive	To update	Hndrsn
SEMP TOSHIBA	LE 4057I (C) 9235	Connected but not browsing	I don't know		Wilmar Farias
TOSHIBA	26EL933G	Does not turn on, no stand by light	K4a60da shorted out	Replace fuse and the 2 k4a60dar	Hugovitch
TOSHIBA	25EL933G	Does not turn on, no stand by light	K4a60da shorted out	Replace fuse and the 2 k4a60dar	Hugovitch
TOSHIBA	MS 7980	No sound, no 50v headphone sound output	R968 470r open	Replacing the resistor	Eletrônica Bianca Ipirá
SEMP TOSHIBA	DL3244	No audio after a few minutes but with audio at the headphone output	Put a 220r resistor on r21 wsound it is without, close to the output	Put a 220r resistor on r$21 wsound it is without, close to the output	Rodrigo cofferi
TOSHIBA	32L2400	It doesn't work, it just stays on, red LED is on.	1.15v missing from defective core ic n801		RPS TECNOLOGIA
SEMP TOSHIBA	48L2400	Does not turn on, no stand-by	Power supply	Utc uk3568l (vf903) and fuse 5a (f911)	Brackmann
SEMP TOSHIBA	LE3273 A	Tsound is sound but the LEDs do not light up, the defect is not a bus	At the bottom of the power supply board tsound are 2 diodes d401 and d402 in short		resistronic resende
TOSHIBA	55C350KB	The LED blinks continuously	Defective led bars		Alessandro Barcelos
TOSHIBA	MS7860MUS	Sound turns on normally and turns off	Stays in protection or turns on and no sound comes out	SMD transistors HQ814 and HQ815 remove both and the sound returns to normal	mamilha
SEMP TOSHIBA	2051NAV U18	Sound very low, volume at maximum	The cause of the defect was the completely dead capacitor c613=220uf/25v		ELETRONCA EM CAEM
TOSHIBA	LE3278I	Green LED pulsing (12v power supply oscillating)	Rectified diode dp9 (do not measure and change)	Dp9 diode replacement	RPS TECNOLOGIA
SEMP TOSHIBA	32L2400	TV turns on standby but doesn't turn on.	The dc dc regulator n801 fr9889 input 12 votes but did not have 1.15 votes ok at the output.		GALILEU ROCHA
TOSHIBA	40RV700FDA	Orange LED flashes, turns off after a while, unstable voltage across the main board connector.	It was noticed that some tracks were broken from the power supply close to the main board connector, capacitors cm859 and cm856 were defective.	All the tracks close to the power supply connector for the main bridge were redone, all the voltages were correct again but tsound was still no signal, I went to the tcon board, as the main board turned on normally, so I removed the cable from the tcon board and the black light turned on. So I removed one of the cables from the tcon board and half of the image turned on, so I cleaned the tcon board connectors and it later worked. If it doesn't work, try checking the tcon board like I did.	Charles Silva
TOSHIBA	43L2500	The screen LEDs don't light up, buses ok	1.5 mega open resistor r707 and ci bad led driver, n701 oz9902c		Ariel Santos
TOSHIBA	37XV650DA	Frozen strip of image at the top of the screen	Tired capacitors	Replacing the smd capacitors on the main board	Claudio
