SAMSUNG	PL43F4900	It doesn't turn on, when it turns on, voltages vs and va appear and it goes into protection.	After separately checking the power supply without the main board, using a 100r resistor from the ps_on pin to ground and 3k3 of the stdby voltage (5.2v) to the so vs_on pin, all voltages appeared normal. Even without the main board, I tested it by connecting the y and zsus boards, the vs and va voltages remained unstable, all that was left to do was check the main board, I turned off the bluetooth module and the TV turned on without showing any irregularities.	Replace the wibt40a bluetooth module.	edumiguez

SAMSUNG	CL29Z43MQ	I'm sound	Remove the q602 smd transistor, next to the sound output.	Remove the q602 smd transistor, next to the sound output.	DJ PITUKA
SAMSUNG	UN32D5800	Stand by LED blinks until it stops and does not turn on the TV.	Smd transistor ic205 in the main, heating up a lot, due to the shorted capacitor c1020.	Replace of c1020.	Online Eletrônica
SAMSUNG	UN40F6400	Sometimes it turns on and works, sometimes it doesn't turn on, the LED flashes 2 times quickly and the power supply relay keeps hitting, but it doesn't light up the screen or work, it stays in this cycle indefinitely.	I tested the power supply, I tested the LEDs, I tested the main board and I tested the tcon, I forgot about the joystick/bluetooth/wifi module.	The defect was in the bluetooth module, just changing it solved it...	MIGUELTV
SAMSUNG	LN26D450G1G	TV turns on when it heats up, turns off sometimes turns on again, then turns off again	Ci 205 3.3v regulator changed ref: 1117z	I just replaced it and the problem was solved	beto_eletrotec
SAMSUNG	UN40H4203	Turns on and after a few seconds turns off, all normal voltages at the power supply	Shorted main board	Replace the main board or remove the ps on/off pin and turn the LEDs back on	INFOHELP Arauá-SE
SAMSUNG	50C430A1M	It doesn't turn on, the relay at the power supply keeps knocking.	Shorted main board	After checking and noticing that the power supply and all voltages were normal, I discarded the power supply, then I scanned the zsus and ysus boards and noticed that both boards had their transistors and were in perfect condition. I isolated the main board and it was found that the short came from it. This type of TV is not advisable for laypeople to attempt to repair, as they have high voltages on the boards and are dangerous. but my problem was resolved and delivered to the satisfied customer.
