If I buy a plasma TV online and it goes wrong in the first year, when it is obviously under its one year manufacturers warranty, does this mean if Ihave problems I need to deal withthe online shop - or do i Just call Panasonic or Hitachi etc direct? And will they come to me, or do i have to post the plasma to them (v expensive). Or does it depend on the individual shop, or make of plasma? I'm very seduced by cheap deals online - but don't wanna regret it later!!!!!
