Good day,
Can somebody please help me with my SAMSUNG 40" LCD TV power supply issue. The first problem before was while we were watching, the TV was flickering then goes off. So I opened the back of the TV and figured out that the fuse was blown. After replacing the fuse when I turn on the TV the fuse immediately blown. So I've suspected that there has a short somewhere in the Power Supply. I tested the two mosfet STP9NK50ZFP and it was shorted so I replaced the two with P10NK60ZFP as an alternative because I can't find an exact model of that mosfet. As I turn on the TV again the TV opened but the screen flickers again and the TV goes off again. So I've check the power supply and the two mosfet that I've replaced become shorted again and the 3.15A fuse also blown.
I've read the recommendation of some expert of this group to make a lamp automatic current limiter. So I buy again the two mosfet and replace the fuse and plug the TV to the automatic current limiter when I've turn on the TV the lamp lights up becomes bright and the light is flickering. I've test with multimeter some parts and it seems ok. Can somebody help me how to troubleshoot the power supply.
POWER SUPPLY MODEL: BN44-00197B
Many thanks to you all.
