Fuse??

[Etca4]

One of my hdhr tuners seems to have stopped getting any signal.

Is there a fuse between antenna connector and board?

Otherwise seems to work correctly. Other tuners ok and working with this broken unit's antenna.

Maybe a power supply issue? If you have another identical HDHR, try swapping power supplies and see if the problem switches to the other unit.

There isn't a fuse or anything replaceable like that.
