Dead Tuners?

Howdy

Been enjoying my TM Nano 3t for a while now then whilst watching last night it appeared to just cut off, seems like the PSU was dead, I have compatible spares so it was revived but I wasn'rt getting a sat signal on either tuners.

I've plugged in a spare sky box which gets a signal on both cables.

Sooooo....is by box dead?

Cheers all
