As far as I’m aware, you have to be able to establish that the goods purchased were “not of reasonable quality”.
With big ticket electrical items like TVs and consoles, it’s generally agreed that they should be of reasonable quality to last 5 years. If it breaks down after your initial manufacturers warranty, the burden of proof on the lack of quality falls to you, the consumer.
If your PS3 failed because of a “yellow light of death”, and is an original “fat” model, you’d probably get away with whinging to a retailer that this is a known fault etc and get it swapped. If it’s anything else, you might need to get an engineers report to prove that the item is faulty due to not being of sufficient quality at the start.
From the fault you described previously, it sounds to me like it’s trying to update with a corrupt update file, and I would try the hard disk trick mentioned first before trying to get a refund, as any refund will be for a bit less than you could reasonably get a good condition 2nd hand one from.
