My fax machine wont accept or recieve any...

my fax machine wont accept or recieve any faxes have had it since 2007, had a thunder storm last week and it hasn't worked since, don't know if this is the cause of the problem because everything else works, is it worth replacing? and what is it that needs to be replaced? or will it be easier to get a new machine and if so would you be able to tell me where from i am situated in Yatala QLD
