Samsung Zipel

Hello All
I have Samsung Zipel SRT686LWI, i bought it from Korea.

The Refrigerator stop working, I mean no compressor voice, LCD work fine, i check all sensors, all are working fine, i do that by press test buttons,

it's have two boards, main control(DA41-00280A) and convertor(DA41-00288A) , After i assume that convertor are the problem, i bought (DA41-00536A) it's almost identical (i don't find the original one over the net). after i test it, i got same result, ( after i connect plug, Refrigerator start and little sound comes from compressor like it's try to start, and then gone).

Please, can you help me, i want to know where the problem, from compressor or anything else.
