Re: All TVs in house have no signal
Just noticed the amp that the OP has linked in post 11 is a masthead driver, so assumedly there must be a top unit at the aerial end driven through the coax. If this has failed there will be no signal in the main downlead anyway. Most people leave these amps powered 24/7, so if you turned it off (as you should) to change the connections & then turned it on again, this may have triggered a fault.
