No Signal on TV

Live hub is on an is available on the network.  Can move files to and from the live hub directories on the network.  However, the TV indicates “no signal” .  I remember having this problem before and entered an address into the browser bar which resolved this issue.  Do not know the address.

Any suggestions?

Hi there, how is your Hub conencted to the TV? Composite, component or HDMI? What if you try with another connector then? o.o
