Make	Model	Symptom	Problem	Solution	By
SEMP TOSHIBA	DL3244	No image, backlight on	Cd25 and q3 shorted.	Capacitor is 10μF and q3 is a pnp transistor, not a fet. If you put fet channel p it works, but t-con is noisy.	André
TOSHIBA	LC3255(A)WDA	Inoperative - no stand by	Removing the power supply harness to the main board, the 12vdc supply came back	On the main board, capacitors c878 and c879 were found shorted, removed and replaced, turning the TV back on	Adenor Lino
TOSHIBA	LE 4057L	Turns on, without blight, image, and disarms, LED remains green.	Cw961,963 do +b do bl.		Jorge
TOSHIBA	2015NM U18	Strw5453c burning	Checked all power supply components, everything ok		Pasqual Spinelli Filho
TOSHIBA	2015NM U18	Strw5453c burning	Checked all power supply components, everything ok		Pasqual Spinelli Filho
TOSHIBA	2015NM U18	Strw5453c burning	Checked all power supply components, everything ok	You need to invert pins 4 and 5 of the strw5453c	Pasqual Spinelli Filho
SEMP TOSHIBA	TS2018		I don't know		Nick
TOSHIBA	40RV800	The light bulbs blink but they don't turn on, and when they turn on, the power supply buzzes.	Change the main capacitor of the primary, the largest on the board, 180uf x 450v		LS ELETRÔNICA
SEMP TOSHIBA	LC3255	Cuts digital tuning or does not enter digital channels intermittent	Cold soldering on smd n100 integrated circuit	Resolder the ci apply soldering flux use a blower be careful insulate the capacitors around them so they don't come loose	PAULO PINHO
SEMP TOSHIBA	DL3245(A)	Sometimes it doesn't turn on, or keeps turning off. returning to standby	N805, 3v3 regulator giving 2.8volts, close to the processor		Eletrônica Cecé. Brumadinho MG
TOSHIBA	48L2400	Turns on, standby comes on, press power, the TV turns on, writes Toshiba and very quickly the logo goes off and the LED turns green and stops functioning, it does not obey commands, nor does it accept turning off, in other words, it stops operating.....	So I was unsure if it was a backlight, as I had a new kit and had the cable that goes to the rulers, I tested it from the outside without having to disassemble the TV and confirmed that the defect is in the LED panel itself.	I had already picked up a 48" that did this but I didn't remember that the defective kit makes this model act as protection and stops the processing.	MIGUELTV
TOSHIBA	TV 2998 LEM2	Low and noisy sound	C671 c672 c679= all 47/25v and c449=1000/16v near the flyback	Electronics paroama. 05/20/2022 Friday	FLAD8
SEMP TOSHIBA	32L2600	Burning leds	Remove 2 resistors and leave without r634 and r633. reducing the voltage going to the LED bars.		LOGANKLEITON
TOSHIBA	2095	Does not turn on only on standby	Electrolytic capacitor c887		Eletrônica Dumel
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
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	Replace the strg8656 switch ci, 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
TOSHIBA	32L2400 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
TOSHIBA	8012	Works normally and then turns off	Ic901 - tny280pn		Alessandro B. Barcelos
TOSHIBA	MS 8012 MU	Turns on works normally and turns off in less than 3 minutes.	Ic901 replacement - tny280pn		Alessandro B. Barcelos
