following is the photo of the full board. Any clue of what is damage at the board?

Could be anything, it's EXTREMELY unlikely that it's the transformer, they are very reliable.

Most common problems are high-ESR electrolytics, O/C high vlaue resistors, and duff semiconductors.
 
oh well... i measure the output pin of the IC and it show some output. but after the transformer, nothing come out. it just end there.
 
the part number is the same with the board name. which is thx203h. checked output after the transformer. nothing come out.
