TOSHIBA	2987 EMS LEM5	Vertical closed at the bottom	Q830 5v regulator next to the changed varicap	Replace q830	MARCONES DE ARARIPINA-PE
SEMP TOSHIBA	1451NAV U18	Turns on with a loud noise from the chop transformer	C865 with leak		Eletrônica_ND_
SEMP TOSHIBA	LE4056	Backlight off (LED symptom)	Capacitors cw961 and 963 bloated, even so the backlight kept oscillating (hours and hours of analysis), as per the tip sound on the forum, I removed capacitor c722 (at the bottom of the ci n701), the TV stabilized, working normally)		Claudio Jorge Eckert Junior
SEMP TOSHIBA	DL3244(A)W	TV turns on standby from red to green normal power supply but the LEDs do not light up	N506 memory ci	By changing, I got the 5v from pin 3 to the blacklight controller, the TV worked normally	manin
