SAMSUNG | UN46F6400 UN46F7500 | Hitting relay | altered leds | ||
SAMSUNG | UN46F6400 | Stand by LED blinking and does not turn on, power supply does not double voltage | Missing 13volts in qs801 | Ds 806 in power supply, open | LABOTRON |
SAMSUNG | UN46F6400 | Power supply relay knocking, TV restarting turns on and then restarts or turns off. | Ci of the board shorted | Removed the jumper from the jp-801 board | Roger Hobold |
SAMSUNG | UN46F6400 | Turn on and off | Caindo 5v standby , replace capacitor cs802 10uf x 50v | TV CENTER GUAIBA | |
SAMSUNG | UN46F6400 | Power supply relay knocking, tv restarting | One of the likely causes could be the c.i. LED driver. To find out if the defect is in one of the two, simply measure the voltage in diodes d9001 and d9002, if tsound is a high level in either of them, the defect is in the c.i. corresponding to the diode in question. if tsound is a high level in the d9001, the defect is the ic9101 and if tsound is a high level in the d9002, the defect is the ic9201. | Replace ic9101 or ic9201 | NARDINHO ALFENAS |

SAMSUNG | UN46F6400 AG | Turn on then turn off | Relay keeps knocking | Replace ci sl 2013m power supply board | Tec center |
SAMSUNG | UN46F6400 | The power on/off led kept flashing when it was turned on, and the TV didn't turn on, the relay was knocking, when testing the power supply the screen's led kept flashing. | Resistor rs802 10r0 smd alterado para 100Ω, | Replace with a new 10Ω one. | FIIPE FURADO |
SAMSUNG | UN46F6400AG | Arrived at assistance completely dead. After visual inspection and with no apparent defect in the power supply, I verified that the fuse was open. In basic measurement of the diodes, I found the n-channel MOSFET, reference 13nm60n, 11a/600v, in the qp801cs position, shorted. | After changing the MOSFET and fuse, it worked normally again. | AnisioH |
