SAMSUNG Repair Guide: Common Issues and Fixes

Brand	Model	Fault	Detailed Problem	Solution	By
SAMSUNG	LN40B530P2M H40F1-9SS	Does not turn on the inverter	Place a 4k7 resistor from pin 16 of the sem2006 co to pin 23 of the inv_on/off connector		Rafael Sena
SAMSUNG	29K40MQ	Turns on and off at the same time	Fell forward		George
SAMSUNG	UN40C6900	Does not turn on, nor does the LED light up	TV looked like this after lightning struck near the house, right away, tsound was a problem at the power supply	The 2 fuses and the 4 1n4007 diodes of the primary power supply were replaced, the varistor seemed to be in good condition so it was not replaced, the TV started working again after changing the components mentioned.	Lucas
SAMSUNG	UN32FH4205G	This TV arrived at my store with a very clear image, you could barely see anything. water had fallen.	On the v-com board, I identified the problem location, cleaned it with isopropanol, and found four open resistors. rg7 (9k1), rg8 (33k), rg3 (4k7) and rg2 (30r). all close to ci(ic6)	I made the replace by removing the resistors from other boards and it was perfect.	<small>This email address is being protected from spambots.

SAMSUNG	MX-C850/XAZ	No sound in speakers	Power supply board with small signs of oxidation.	Replaced power supply board.	Aomine
SAMSUNG	S19B300B	Doesn't start	Memory ic402	I didn't have another one, I took it out and it worked in DVI	Eletroclaudio
SAMSUNG	UN40H5500	Doesn't start. When removing power from the pmain, the LEDs light up	Mcu sems31. change processor or pmain.		Eletronica Jambeiro
SAMSUNG	UN32FH4205G	Gray image	Qc1 and qc2 changed on the display board	Remove from the circuit and ready normal image	antonio nobrega patos pb
SAMSUNG	PL-43F4000AG PL-43F4000AG	Doesn't start. standby led flasher	Plate and its buffer		Adriano Souza
SAMSUNG	P2470HN	Turns off the lamps when it changes, activates the input	Place a 100k resistor on pin 1 of the IC or 201 of the inverter		Agostinho Mariano
SAMSUNG	LN40C530F1M	Turns on image appears and turns off	Problem in the high voltage sector for lamps	Changing the lamp infrequently	Marcos Paulo infotron-ltda
SAMSUNG	32PHG4900/78 TPM15.5L	TV doesn't turn on. ci pf6003ag damaged.	High temperature when welding it.	Solder this IC as quickly as possible, at a lower temperature as it shorts out very easily.	Denys de Sene
SAMSUNG	32PHG4900/78 TPM15.5L	TV doesn't turn on, no stand-by.	Power supply board, CI PF6003AG (SMD 6 pins)	It was replaced by the CI OB2273, pin-to-pin equivalent. If after the replace the voltage remains low in the secondary, place a resistor of approx. 1k in parallel with the photocoupler LED.	Denys de Sene
SAMSUNG	T220M	Turns on with sound and image and after a few seconds the lamps turn off	Burned out lamp	Replace the bulb or jam	Johnny
SAMSUNG	CL21ZMQ KSCA	Dark screen increases screen delay line	Diodo zener dzd207	Replace dzd207 open or short	eletronica global chiquinho
SAMSUNG	CL21M6MQ	It doesn't turn on, it just kept the LED on, after pressing it it would go off and she would try to put it away	Polyester capacitor cr404s shorted and resistor r414 burned	Replace the cr404s and r414	Rafael
SAMSUNG	PL42A450	Checkered image, and it heats up and tsound are lines from top to bottom flashing.	Controller board memory t.	To replace. the lines flash even when the flat that connects it to the main switch is turned off.	JOAOMVJR
SAMSUNG	PL434900AG	Does not turn on, stand by LED is off, only main board LED blinks a few times	Capacitor, CS809S position open on the power supply board	Replace it and check the voltages vs,va	KL. ELETRONICA
SAMSUNG	2033M	Turns on and just flashes the screen and turns off	Weak light bulbs	560Ω resistor between bl_on pin and ground. placed at the connector input coming from the main board. canceling the lamp sensor.	Cláudio A.
SAMSUNG	LT27A550	Screen LEDs turn off and on	Ci oz9998bgn	I replaced the ci smd oz9998bgn solved the problem	Jetro
