SEMP TOSHIBA	LE3278I	Turns on, then always appears red and goes out. Audio works normally. Intermittent defect, sometimes it worked and went on for hours without the defect occurring and sometimes it did when turned on.	Trails with cracks on the LED bar, close to the connector.	Retrace trails	Caio
TOSHIBA	LC4246FDA	No Audio, only through headphones	Smd transistor position v204 3904	The mute transistor was removed, audio returned normal	MULT INFORMÁTICA E ELETRÔNICA
TOSHIBA	2050MAV U17	Does not turn on, LED flashes quickly	C440 de 9n1		Gilvan
TOSHIBA	TV2134	Buzzing in the phone and hanging up	Q606	Replace for bd135 observing polarity	Marcondes Ohm Eletrônica Jaicós PI
SEMP TOSHIBA	LE3256AW	Does not turn on, only green LED is on directly	Corrupted flash memory	N506 memory replace	PAULO PINHO
SEMPTOSHIBA	TV2134 (C ) SL SK11	Image with side band and OSD deformity	Curto no zener diode zd208	Working 100%	BIOSNOT MANUTENÇÂO ELETRÕNICA
TOSHIBA	TV2989 LEM3A	Sometimes it works, sometimes it doesn't, standby off, secondary or no voltage	Defect and an open or altered 1m resistor(r865) is well hidden next to the rectifier bridge(d801)	Replace r865 1mega	Jhonnes Eletronica
TOSHIBA	TV 2157	No sound at all	Change 220uf x 16v volt capacitors next to the sound output and run to the hug		eletronica publisom de natal rgn
SEMP TOSHIBA	DL3254	The TV turned on and the screen lit up and went out immediately.	The beginning of the defect was the screen was completely off, 2 LEDs were found open, replaced, another problem appeared, the TV would turn on, the screen would flicker and go off, I found r721 of 22r open, replaced and the TV worked normally.		Strutz
TOSHIBA	LE3256(B)W KDLXXRS611UN	No image, with sound and back light working.	Shorted capacitor CD25, on the display board (tip of the board).	I lowered the circuit current. I added a 4r7 resistor in series to r759 (4r7)(underneath the board), on the inverter. the measurements were 238.2v and 131ma, with back light at 100%, for 229.8v and 99ma.	Eletrônica R-Tec
TOSHIBA	2977 SL91	Turns on with the vertical closed and turns off, the vertical burns out	Chap. 309 uf100x50v, causing a short in the power line	Replace without measuring cap 309 vertical prox	ELETRONICA SANTA FÉ CASSILANDIA-MS
