TV broke after 2 months

Hi, my elderly Mother was bought an Aim LCD TV last year from Pick n pay and she never got a receipt.<br> The TV power supply suddenly went off and never came back on. This was only after 2 months.<br> When I called Pick n Pay they said there is nothing they can do without proof of purchase.<br> The product clearly states on the box that it was packed for Pick n pay. <br> Also surely the manufacture warranty still stands and why cant they track the sale via serial number or something.<br> I feel this is a very unfair situation.<br> Please help.<br> Regards<br> Kathy
