TOSHIBA	TV2134SKY	Relay knocking tvc does not turn on, intermittently,+b oscillating 100v to 150v	C609 pine 4 ic 601 altered	Replace c609	Gabriel GXP
TOSHIBA	TV 2996	No horizontal synchronization	Electrolytic capacitor without capacitance	Replace capacitor c214 (1x50v)	Julio Cesar
TOSHIBA	TV2998 LEM 2	Reduced vertical at the top and bottom, and image rocking	The 12v voltage was low at q 830, because at its base tsound is a 5v6 zener, which was connected to another in4148 diode, I removed the in4148 diode and put a 0.33r resistor in its place, and went into mode of service I adjusted the width. it turned out beautiful.		JOSE MARTINS
TOSHIBA	U11 1483	White image. white screen, with sound. If you enlarge the screen, retrace lines appear.	C446 (4,7x250v screen), on eeprom.	Replace the capacitor (which is the easiest). check the rgb voltage. If everything ok, re-record or replace the eepron.	R-TEC Eletrônica
SEMP TOSHIBA	TV 2090 U13, U14...	After changing the leaky fly, tsound was only a blue screen, and no sound (mute)	Q612 with leak (it is on the standing plate)	If removing Q612 works, replace it, it could be bc557 adjusting the position	jasvan souza

TOSHIBA	37HL57 HL57	No audio or intermittent audio.	Rc62 and rc 67 open or changed.	These resistors are located at the bottom of the main board at the height of qg01 and on the opposite side of the ci.	WAGGUINHO
TOSHIBA	37HL57 HL57	No audio or intermittent audio.	Reset missing on pin 16 of qg01	Replaced smd ra62 resistor. (it is next to qg01.	WAGGUINHO
TOSHIBA	37HL57 HL57	Normal power supply, starts relay and disarms immediately, goes into protection. doesn't work.	The defect is caused by the smd resistors ra117 and ra118, they may be altered or open or even with cold soldering on the terminals, these resistors are on the bottom of the main board (av) when they are altered the television may operate intermittently, or operate without audio .	Resolder the resistors or replace ra117 and ra118.	WAGGUINHO
