Hi peeps
New to Cable/freeview TV so help would be appreciated

I live in RH19 - East Grinstead
I have a relatively new (2 years) Ariel, Wolsey WFAV25 Masthead Amplifier & PSU - all installed by an Ariel company. All was OK until 2 weeks ago when all signals failed (digital and analogue) - I think I am pointer to Croydon, certainly north of EG.
I suspect the Wolsey kit has failed. Is this normal? I am about to order a complete new set of kit from Amazon. Do you have any other ideas. (Have checked all fuses, plugs and connections)
Thanks

Mike
