Sony KDL-32BX330

[SEAWOLF]

I have a Sony KDL-32BX33O to service which has a blown fuse in the secondary side of the power supply. I have checked diodes and transistors and
I have not found any to be shorted, and I have replaced the fuse and it has blown again.Can anyone offer a solution to this problem?

The picture of the power supply is not very clear so difficult to tell anything from it. Can you post sharper clearer pictures.

Check the two diodes, the bridge rectifier and the mosfet alongside. For a fuse to blow some component is probably shorted.

Can we get better focused clear pictures of the top and bottom side of the power supply board?
I see two fuses on the hot side, one in the main ac INPUT, small one in the STBY POWER supply hot side. I do not see fuse on the cold side looking at your pictures.
