Should you really have to fiddle about like this on something that cost you over £100?
If you bought a mobile phone or a TV, would you still take them apart and try and fix the problem, or would you return them under guarantee to the shop you bought them from?
Trouble is, all the time people fiddle and solve the problem, the manufacture remains blissfully unaware there is a problem, however if the they get umteen returns, then they become aware quickly as this starts to cost them money.
