Just removed the back again. It is the power supply board. DYP-50W3. There were three fuses on the board. A ceramic fuse close to where the power cord goes in, it's ok. My blown fuse was glass fuse.
Hi Tim, l was in the process of taking a picture of the board for you. Please advise. Do you still feel it's the whole board? The fuse is the one at the end of the red pen.
