I would first start by unplugging the topside from circuit board wait 30 seconds then reinstall plug. Check for any burn marks or damage to board. The issue is that we don't know if it is a bad topside or a bad circuit board and without another topside there is no way to be sure. The fact that you can not get it out of EC makes me think that it is a bad topside.
