Make	Model	Symptom	Problem	Solution	By
SAMSUNG	UN40D5003 BN44-00473A	Standby LED blinks and does not turn on	Releasing the cable that powers the main one activates the backlight and the power supplys, but it is the power supply board.	Leaky QQ9101 transistor, backlight shield near the backlight connector.	Easi
SAMSUNG	LT27B350	Sometimes it works, sometimes it doesn't. Sometimes it turns on and off, displays the logo and turns off. The LED blinks twice five times.	See Q202, transistor (marking \\\"1E\\\"), which is on the signal board, close to the socket that comes from the power supply	replace it	Easi
SAMSUNG	UN55KU6000	Stand By Flashing and does not turn on	Display defect	Flat bottom plate main board - isolated more or less 15 tracks from bottom to top - Perfect picture without anomalies.	Paulo Braz
SAMSUNG	UN40K5300	Operating with noise (Cricket Type)	Ripple on 12V supply	CM855 and CM860 capacitors puffed or with high ERS. Just replace them.	LYRTON HORTA
SAMSUNG	UN55MU6100G	Lower LED current	After replace the LEDs, make the modification	Swap the R9381 1R for an R 5.6h 3w	Medeiros Eletrõnica Barbacena MG
SAMSUNG	UN32FH5030G	DOES NOT TURN ON, MAIN BOARD SHORTS ARMING AND DISARMING THE PROCESSOR	C.I U701 SHORT AND STUFFERED BUTTON CAPACITOR	REPLACED THE C.I, BUT IT'S NOT ON THE MARKET SO I REPLACED THE BOARD	Servitron
SAMSUNG	LN40B530P2MXZD	doesn't start. Fuse open.	QI820 and QI821 shorted.	I replaced the 2 with the TK8A50D and it worked normally.	RYK
SAMSUNG	PL43F4000G	Turning off by itself for no apparent reason.	The thermal paste on the mosfets becomes very dry, so the heat generated by the mosfets does not pass adequately to the aluminum heatsink, the circuit current rises and activates the protection. solution, remove all the old paste and place a new one. This also applies to other plasma models.		Ferraz
SAMSUNG	40F5500 BN44-00645	power supplyS OF 12, 24 AND INVERTER ZERO	ZDS803 WITH LEAK, Tsound MUST BE 15 V AT THE KATODO	ZDS803 (BC SMD TYPE)15V LEAKAGE PLACES A COMMON 15V	ELETRONICA BRAMBILA
SAMSUNG	510N	turn on and off lamp	just to correct the tip I gave before, the diode cathode goes on pins 10 and 9 of the sem2004 ci		Pedro Igor
SAMSUNG	510N	Flash lamp and turn off	usually 1 of the 2 lamps is burnt out, if you can't replace the lamp I will teach you how to turn off the protection of the ci sem2004, it works normally with almost no replace in lighting	Place a 330r resistor on pin 1, a 2k2 resistor on pin 14 and a 1n4148 diode with the cathode connected to pins 10 and 11, then join the 2 remaining ends of the 2 resistors to the diode anode	Pedro Igor
SAMSUNG	UN32F4200AG	doesn't start	SHORT CAPACITOR	replace OF CM801 (101K 1KV)	ROGERIO
SAMSUNG	UN40H5500	Burnt backlight	After replace the LED bars, the LEDs blinked non-stop.
