My DM800HD stopped working!

[enrules]

Hi,
I have a DM800HD (original) and it has been running fine for over two years, however last night it just would not turn on! Nothing comes on, the unit doesn't even power up, but the ethernet lights flash and the box makes a buzzing noise. Please help.

Thanks

I've never looked inside any cable boxes but there might be a fuse of some sort inside that has blown ?

Your power supply is broken on the box, it's not kicking out enough voltage that's why you are only getting Ethernet lights, you need a 12v 3amp power supply
