My DMR-EH80VEB IS COMPLETELY DEAD

Hi, I have the same model PVR which stopped working in the same way, in answer to your question, yes there is an internal safety fuse located inside the case under the switch mode power supply cover, WARNING this cover protects against electrical shock, Ie there are full mains supply voltages under the cover so make sure that the power cable is completely disconnected before you remove the safety cover. if the fuse has blown make sure that you replace it with a quick blow compatible type.
Thi did not help in my case because a component had failed in the power supply board so I am still looking for a service manual, anyone know where I can buy one.
