Make	Model	Symptom	Problem	Solution	By
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
TOSHIBA	32L2400	Turning on and off continuously (before just st-by, it didn't turn on)	Replaces dc/dc converters n802 and n801 - fr9889	After changing the ci n802 and n801, both dc-dc converters, one of them accidentally ripped out a 10k smd capacitor (c803), which is between pin 01 and pin 03 of the n802, putting another capacitor in place it started working normally again
SEMP TOSHIBA	LE2458(A)F	White screen	Ci n802 next to the flat that connects the screen, fr9886 I put fr9889 and atv worked perfectly.		Real Eléctron Carvalhos MG
TOSHIBA JVC DAEWOO	SHLD5509F-101H	Flashing red LED does not turn on	Power supply diode d20 replace without measuring	Replaced primary sector power supply diode (d20) on the power supply board	Maike sorriso eletrônica
TOSHIBA	40L5400	No voltage on the secondary, stand by LED off, and voltage on the capacitor 179v on the c901, on the c.i fan6755w voltage of 1.6v on pin 1 vin and 53v on pin 8 hv	Smd zener diode shorted VDW908 of 6v8 and the control c.i fan6755w after changing it returned normal.		Eliel
STI TOSHIBA	LE3252A	Does not turn on, does not stand-by and has the power supplys	Corrupted memory	Rewrite memory	Wesleyborges7
SEMP TOSHIBA	LC3246(B)WDA	LED does not turn on, flashing green and red	This TV arrived flashing the green and red LED, measured the power supply voltage and it kept oscillating, checked that it was setting the overvoltage protection, checked the optocoupler n902, zener diode zd955 and transistor q954, all ok, removed the optocoupler and the power supply It stabilized at 12.6v, the zener was replaced with a 14v voltage and it started working again.		Sajage
SEMP TOSHIBA	48L2400	The logo appears and after 30 seconds to 2 minutes it turns off and returns to stand by. and if you turn it on again it happens again	Bad ci n801 close to the processor. responsible for v-core	Changing the n801 It's a fr9889	Eletronica SV - Guaira PR
SEMP TOSHIBA	TVC102-CR	TV does not turn on, with loud buzzing/whistling noise	Horizontal output transistor q404 (2sd1427) shorted. When removing it and turning on the TV, the horizontal frequency reached more than 24kHz on the transistor, causing the component to burn out.	Following the tip from colleague moraes sptv campinas, the capacitor c408 (10μF 16v) was altered. Replacing the capacitor and horizontal output transistor solved the problem and the TV started working normally again.	Rgs011
