Make	Model	Symptom	Problem	Solution	By
TOSHIBA	LC 2010Z	The device turns on, the display lights up and then turns off, triggering protection.	Check the inverter circuit, in the protection stage, if the capacitors are shorted; c30/ c31/ c32 of 100kpf. To turn off the protection, short circuit the collector and emitter of transistor q9, and check if the device works.		Miltom eletronca micro e eeprom
TOSHIBA	LC 15/2010Z	Display without video white screen	If the voltage at the output of the regulator u27 is below 9vdc : completely white LCD screen	U27/d40/c370/c369 with higher frequency d40 with leak	Miltom eletronca micro e eeprom
SEMP TOSHIBA	1482EAV U7	Stand by light on but not working image	Transistor q430 solder free	Resolder the same	Rogerio silva
TOSHIBA	TV 2998DS LEM	Low power supply 75v.	Micro tmp87ck38n1e98 disconnect pin 7		luiz de sao
TOSHIBA	TV2177A	N/f LED lights up then goes out slowly	C-884 from b+ sold out		luizandradina
SEMP TOSHIBA	TV1484	Does not turn on LED stays on	C872 35v 33uf electrolytic capacitor		jefersonpierini
TOSHIBA	TV 2987 LEM6	Vertically closed and then disconnected	STV 9302a output shorted and capacitor 100x 35 volts dry and resistor r 327 burned	I replaced the capacitor, resistor and put a 9302h output, it replaces the other one without seismic on this TV, ok guys	HELIOMAR
TOSHIBA	TV2093-JAV U14R U14R	Inoperative and the LED does not light up	Strw5753 burned, d876 changed, cap 864 changed and r876smd 220oms burned	1st I replaced strw, cap864 and the 5.6 zener diode and then I did a thorough search on the smd as it still didn't work with the help of a magnifying glass I saw the 876smd resistor with a small hole I took it out, measured it, replaced it and it worked fine	center téc
SEMP TOSHIBA	TVC 102	Doesn't start	Transistor 2sa1320 (q813) power supply board shorted base emitter	Responsible for powering the IC responsible for the horizontal output	Fernando Siqueira
DVD TOSHIBA	SD 3020VK *	The message on the display without dialing.	I fixed the driver and it works normally, after 1 hour it started to stop reading.	Just replaced the driver and everything was ok.	wagner
TOSHIBA	TV2988LMS LEM8	Red screen with horizontal lines.deactivating by cir. protective	I checked RGB voltages on the 901 collector.	I removed the tube socket and checked to see if it was blocked. between filament and pin r, wsound it was found to be short. I laid the TV with tube down, turned it on and tapped the bulb until it released residue that was shorting out between the filament and g grid. TV returned to FC. normally. I alerted the client if this was the case. If it came back, the tube would have to be replaced.	OLÍBIO - ELETRÔNICA ESTUDIER
TOSHIBA	20A76MU U8	Dead	Blown fuse		anos luz
TOSHIBA	TV2957 FFS	Distorted butterfly-shaped reduced frame	Broken wire inside vertical side deflector coil	Ok	jair felix cap poço pa
TOSHIBA	TV2157NFS U18	Intermittent defect. Sometimes it turns on, after several hours and turns off, leaving the LED flashing	I suspected the photocoupler and circuits connected to it, since the voltage dropped at +b to 50 v and the voltage on d885 went to almost 3v, triggering cir. 5v reset.	As it is an intermittent defect, I noticed that it replaced in det. temperatures, sometimes by even moving it (bending the board), I even thought it was cracked, or some cold soldering, but the capacitor c865 that connects the tr. excitement. from the photocoupler to the ground tsound was a leak. This one took a while!	OLIBIO - ELETRONICA ESTUDIER
TOSHIBA	TVC-145	Vertical opening and closing unstable image	Transistor q 302 bf 422 direct swap		teceletrik
TOSHIBA	TV2922IFS LEM 9	Burning fuse	Q801=strw6554a shorted, r876= 220r value changed and d883=rl3a shorted.	Replace of components	NILTON-AVARÉ-SP
TOSHIBA	MS6542CD	Dead power supply ok.	Xc701 crystal replacement	Valid for all mods from ms6528 onwards	artemio
TOSHIBA	TV 1030M U17	Vertical closing intermittent	Remove glue wrapped around q405 and q430		ramiresrc
TOSHIBA	TV2957FFS	Menu keeps appearing all the time	Move the keyboard cable away from the power supply and fix it somewsound.		fabiusmax
TOSHIBA	TV2092 U16	Dark image screen with 150volts	Screen capacitor on the kinescope board	Replace without testing because in the test it measures as if it were good.	ANTONIO NOBREGA(PATOS PB)
