You don't have a 6 year warranty, you rights become limited after 6 months so the onus is on you, not the retailer to prove you are entitled to that replacement or repair.All products have a SIX year warranty, that is the law. Goods are to be fit for purpose for up to 6 years. However, if you buy a cheaper item you should not expect that to last 6 years, Richer Sounds are not doing you a favour with a 6 year warranty, it is the law! Very simple!
If you mad enough to buy and subscribe to Sky glass, that will have a longer warranty, if your glass fails, after their warranty period, ring them up to cancel, they will ask you why? Say equipment has failed, and they will send a replacement. That is what they do with the set top boxes, obviously I don't know if it will be the same with the glass?
I will be sticking to the dish, and SkyQ, there is a greater selection of channels and I am not tied into any broadband or a service contract.
Don't confuse a warranty from the manufacturer or retailer to your consumer rights.
