Turns on and off and returns to stand by | 2 capacitors of 3300 mf/10v on the 5 volt line practically exhausted. the impression was that tsound was a defect on the y sus board. when it was isolated from the z sus board the TV turned on normally. paca y sus tsound was no short. what was left was the power supply board. the relay tripped because the 5 volt power supply was not supported. | Changing the 3300 mf/10v capacitors and checking the power supply capacitors. tsound were several with low capacitance and high esr. after that the tv started working normally again | jose carlos |

It doesn't work, plugs it in, you hear the relay arming and tsound's no image. | After checking the ysus board, I found transistors q22, q23 shorted and fuse fs 202 open. | Replace damaged components, general board check. | arock |

Burning q101. | After replacing all burned components due to c102 being shorted, the new MOSFET burned again. check r106 (1.2k), if it is open the mosfet shorts out as soon as the power supply is energized. | electronics supply parts - Gramado/RS | |

When turned on, it turns off immediately and is like rebooting into the Samsung "logo" | Voltage failing that comes from the power supply to the main board | For the second time I got this defect and almost ate bronha, the defect is in the power cable socket that goes from the power supply to the main board, if you remove the connector on the power supply you will see that it has been heated and this causes connection failure/bad contact. In both cases I replaced the complete cable. | MIGUELTV |

Turns on but tray doesn't open, just blinks open. Does not reproduce image via HDMI or RCA. | I took the tip from my friend "littlecarlos" and went straight to the 1000uf/10v capacitors. I replaced the 3 ppcf1, ppcf2 and ppcd1 and also installed 3 1000uf/16v motherboards. It worked perfectly!! thanks for the help friend | First thing, replace the 3 capacitors without measuring. In my case it was just that. | RYK |
