TOSHIBA TV2999KMS
LEM7 		It works for ten minutes and then the power supply drops to around 50v (note: only with the lid in place) Strg8656 heating up and having problems, replacement of the strg8656 key switch, but as I didn't have the same one, I did a datasheet search and verified that the strg5653 had identical pinouts, and even heats up less than the original. fabiusmax

V2 		Turns on stand-by when you press power, turns on normally +/- one minute, turns off and doesn't even turn on stand-by. Photo coupler > changed nw950 I replaced the photocoupler > nw950 bc817 smd note: you can put the normal one, just cut the terminals. Pedrozo
TOSHIBA 2159OFS U19
U19 		TV completely inoperative. Resistor r860 = 220k, it was open. It is located at the power supply close to the main capacitor. I hope I helped my friends. Bruno Rogério

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

TOSHIBA 40L2400
Does not turn on, stand by always lit in red Defective nand memory I measured voltages of 3.3 on the regulators and everything was ok, if the n807 regulator has a voltage of 3.3v, it means that the TV may have a defective N801 or the TV is on, in my case the TV was on and the defect was the memory nand Claudio Eckert
TOSHIBA 48L2400
35019026 		The LED doesn't turn on, blinking red, sometimes it turns on for a few minutes and then turns off and the LED blinks red Going into power supply circuit protection, defective zener diode Replace 5.3v zener diode vd954 Diverso Eletronica
TOSHIBA 48L2400
35019026 		The LED doesn't turn on, blinking red, sometimes it turns on for a few minutes and then turns off and the LED blinks red Entering into protection primary circuit that turns off the TV, replaces 5.3v zener diode vd954 Diverso Eletronica
SEMP TOSHIBA U18
It turns on the LED blinks super fast but the TV doesn't turn on, it just blinks the LED It wasn't c865 it wasn't c876 it wasn't c884 it wasn't c440 it wasn't photo coupler it wasn't width cap and it wasn't c865 in my case it was bad tsh it shows as good when measured with a multimeter but don't be fooled it was tsh ok good luck to everyone eltronica publison tec jorge alves
TOSHIBA 40L2434DG
Display failure, sometimes it doesn't turn on Unv4031-01y panel, capacitor below dd1 shorted Put 10µf on the panel next to dd1 Edson SP
