Make	Model	Symptom	Problem	Solution	By
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
SEMP TOSHIBA	40L5400	Turns on the power, the stand-by LED flashes very quickly and it goes off... after that the TV doesn't turn on, it stays dead.	5volt power supply absent in the n806 (fr9889), note that the 12volt power supply is 6.7v which is supposed to be low, but in stand-by the 12 volt power supply is a little more than 6v... ok ....	Swap n806	MIGUELTV
TOSHIBA	32WL3A63DG	Turns on after 2 minutes LEDs turn off, and tsound is sound, the LEDs with the tester are always on	LEDs with a lot of consumption, at the power supply (17mb211s) voltage goes from 90v to 47v; 2nd ic mps 1747 ; 3rd c113 68uf/100v with 47uf		joaquim cunha
SEMP TOSHIBA	LC4246W	The 12v power supply was intermittent causing the backlight to become unstable (screen flashing)	I reviewed the electrolytic capacitors that are around the nb901 oscillator ci and found the cap. cb906 with altered capacitance and esr	After replacing the capacitor, the 12v voltage stabilized and the backlight stopped flashing and turning off.	Alegrete
SEM TOSHIBA	DL4844	With black light without image	2 capacitor on the tcon close to the connector that connects the flex to the screen	Just replace and run for the hug	ANDREI ELETROINFO
SEMP-TOSHIBA	1482 U8	Vertical closed	Q421 and q830 broken	Replace without measuring, if you can't find an original replacement, you can use the d1266 which works fine.	Tiago C. Neves
TOSHIBA	LC3246WDA	Liga sem posterior sem as	Ps on tsound was no transistor near the power supply socket on the v806 main board
