Hi
i have SAMSUNG LED TV UE46B6000 tv. the relais are clicking.
i found out, it start then go into shutdown.
power supply is BN44-00269A
i found a shorted FET (Q9103) , in the led driver section of power supply.
i replaced the FET, the Tv started up and worked short . The image was dark so i increased the brightness in menu. Then the tv shut down and same FET was shorted again. how is this possible
I checked the components near the FET and they are OK.
maybe its a bad driver chip? or backlight are using to much current? i thought it has protection when that is?
anyone can help
