Since electronics have product lives of 6 months to a year before being superseded it is common that they do not keep parts for repairs. Most repairs would cost more than the original product so they replace as often as repair. Some manufacturers will stock parts based on a statistical failure rate and when they are gone, they are gone.
That is incorrect. The retailer owns the responsibility for the warranty from day 1 to however long one can establish rights under the Australian Consumer Law. That being written whether going to the retailer or the manufacturer case-by-case varies.
As @Pags reported contacting JB was more efficacious than Sony at 2 years, apparently just beyond the manufacturer warranty. Whether that is sufficient under the ACL is another matter. @Pags needs to do some research and if it can be documented the new fault is the same as the old, that the TV, considering its price point and any advertised claims, should reasonably last more than 4 years, @Pags should read about rights under the ACL and present a formal ‘letter of complaint’ to JB management clearly making their case, as if arguing in front of a magistrate who knows nothing and closing with what is wanted for the outcome, and with a date for JB to reply.
Unless a good case can be made the outcome may not be as hoped for, but 4 years seems a minimum noting Choice guidance.
Real trouble shooting takes time and therefore money so they do the obvious and get on with their own jobs; warranty work is a cost centre so the manufacturers’ goals are to minimise costs.
As for repairs, it is too common that symptoms are fixed, not the underlying fault. For example if a power supply is dodgy it can cause a short life for another part by generating ‘dirty power’. The repair will replace the part that failed and not even look for why it failed, eg maybe a dodgy power supply. The dodgy power supply could cause the new part to fail similarly to the first. Nobody wants to know about the power supply, often they won’t have the necessary equipment to check since they repair by replacing field replaceable parts that failed, and no matter how many times the same part fails they will once again replace that part until they can avoid further liability.
Relevant experience -
For context to the problem with the Sony TV, the retailer that sold the KWC mixer stepped in at roughly 10 years and made it right by providing a very acceptable store credit. While KWC advertises KWC products are built to last they only offer a 5 year warranty noting my experience is a few years old now so these documents were not current at the time.
