SAMSUNG	LN26B450C4M	Turn on tsound is sound but the image does not appear dark screen	The display lamps do not light up, they are off, I checked all the lamps are ok, I checked the power supply, tsound was no voltage on the inverter, I heard an electrical discharge caused by lightning, I replaced the following components:<br> up801s: fan7530 was chipped;<br > QP802S: K8A60DA Shorted; <br>RP820: 0R12 3W Open; KDS184 SMD diode was open; I changed all the TV, everything was ok	Defect resolved	Eletronica TK
SAMSUNG	UN40EH6030	It heats up and restarts, it keeps restarting until the LED goes out and it doesn't turn on anymore. cools down and returns to normal.	Swap q 852 smd near photo		JOAOMVJR
SAMSUNG	LE32D400E	It worked well, when it was put on standby with a command, it wouldn't turn back on. I had to unplug it to start working again.	Transistor qm852 at the power supply on the power line, with leakage.	I don't know the reference, I took one from a damaged power supply.	BN44-00438A
SAMSUNG	CL 29Z60MQ	With normal sound, no image, with the screen full of retraces when the screen increases	Vertical output circuit	Changing the vertical output circuit la 78045, I used the la 78040 it worked normally.
SAMSUNG	PL51F4000	TV turned on and off	I discovered that the problem got worse when the TV got hot or turned on for a long period of time. which led to the suspicion of some component varying with heat. That was when I discovered, close to IC 1501, the capacitor in position 1024 of 10uf that changed depending on the heat applied to it. I checked the conclusion using a capacitor and a soldering iron.	The capacitor is responsible for filtering the voltage on the ic1501. I placed a common 10μFx25v capacitor and it solved the problem.	Edinei
SAMSUNG	LN32A550P3R	Normal sound screen off	This TV worked normally, but sometimes the screen was off and the sound remained normal. On the power supply board I found 3 swollen capacitors, cm812 (47μfx50v), cm859 (470μfx25v) and cb852 (1000μfx25v), they were replaced, but these were not the cause of the defect. The defect was poor contact in the flat cable socket (LVDS) that connects the signal board to the T-Con board. All I had to do was unplug it and plug it back in to return to normal. To ensure that tsound was no more problem, I applied a little machine oil to the gold contacts before reconnecting.		littlecarlos
