Bought my Freeview DVB-T STB from DSE in 4th quarter last year and it's now dead, turn it on and the HDMI connection to the TV picks up there's something but there's no signal, can't even access any menus, was working perfectly then started giving garbled screens and freezing and now not even 6 months old and it's broken completely :(

It's my bedroom STB too, lounge TV with built in freeview still works so it's not my aerial or reception, is a POS.
