Hi @K44L As @Glenntech says possibly Samsung would be able to offer another warranty at a cost. However free extended warranties (5-6 years) are offered via some stores such as Richer Sounds and John Lewis at the time of purchase. Samsung sometimes offer them too when buying direct or for limited periods via application.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
