SAMSUNG	PL51D490	Doesn't work	I checked the following components; q 5009, q 5002, q 5019, d5010, on ysus, and on zsus q4002. all shorted. After changing them I noticed several bad soldering points on the zsus board. These points probably burned the aforementioned components.	Replace the aforementioned components and resolder the z sus and ysus boards.	arock
SAMSUNG	LT24A350	Does not work, main board killing the supply voltage.	Integrated circuit (ic1204) on the main board is shorted.	I removed this component and the TV worked normally, I didn't replace this component because I couldn't find it for sale.	Carlos Alberto (Eletrônica Baturité)
SAMSUNG	PL43F4000AGXZD	Turns off after some time	Cold solder at several points and mainly on the cs809s capacitor		Carlos eletrônica

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
