Hi again, Shylock!
Why not try exercising your consumer rights? If an electrical item fails to work properly, due to an inherent fault (e.g. poor quality components or inadequate manufacturing standards) within 6 years of purchase, the retailer is obliged to remedy the fault by either arranging for a repair or providing a replacement item.
In the first 6 months after purchase, there's an automatic assumption (unless there's clear evidence to the contrary) that any problem is due to an 'inherent fault'. Thereafter, it's up to the customer to show that, based upon the balance of probabilities, this is the most likely cause of the problem.
Contact the retailer and state that, in your opinion, the only possible cause of the failure is the use of poor quality components during manufacture. Challenge the retailer to suggest an alternative cause. If you can establish that the most likely cause is an inherent fault, the retailer must, by law, provide a suitable remedy.
