STI SEMP TOSHIBA	LE3256(B)W	TV turned on, display doesn't work (works for a short time) and blacklight works normally.	Transistor v818 model 3904 npn of the vcc-panel block short circuited, preventing the mosfet n805 model 9435a from receiving a voltage lower than 12v from the gaite and thus activating the 12v voltage for the t-com board (responsible for turning on the display).	1st test: test the t-con input voltage, (vin=12v) 2nd test: test the voltage on the drain of the n805 mosfet (d=12v)[9435a] 3rd test: measure voltage at the power supply and gate from mosfet n805 (s=12v, g	Jonas Saraiva
SEMP TOSHIBA	LC3258WDA	Turns on red LED and doesn't turn on TV	Ok power supply supplying 3.3v and main board does not activate.	10k smd resistor r156 is open.	Alessandro Barcelos
