can anybody fix this?
No, it would likely take a qualified repair technician to fix it.
There is an internal fuse. Occasionally a fuse in a component might blow and when replaced the unit is fine. But if there is a blown fuse and you replace it and it blows again you will obviously need to get it serviced. I suspect you are outside the U.S. (China?), and shipping might be prohibitive, but I would email ModWright and see if they can help or point you in a direction.
