I bought a 37" LG lsd tv and it packed up after 14 months, I was told by the suppliers that because it was out of warranty there was nothing they could do.
I got in touch with Trading Standards and they said that under the "Sale Of Goods Act 1974" any item should be worthy of at least 6 years usage and they emailed me the letter to send to the suppliers.
They still refused to help so the next step was court action, they then offered me a new tv or £450 but Trading Standards said I should refuse and hold out for the full amount of £850, did this and just my luck the bastads went into liquidation and I ended up with fook all, sold the tv on ebay for £50
Warrantys only cover you for internal faults, Guarantees cover you for anything
