Whilst I would agree that TV manufacturers have been / are guilty of milking the various TV format / display technologies over the past few years, it's a step too far to call LED backlighting technology a scam.
Whilst it is true to say that, "LED tv's arnt [sic] LED tvs at all. They have LED backlighting, but still use LCD....." the ASA has said that it does not object to the use of the term (LED TV) but does require it to be clarified in any advertising.
Whilst the panel in this Samsung may not be a hypothetical true LED display, or an OLED display, no one is saying this.
In terms of the technology itself and depending on the type of LED used, this method of backlighting does offer considerable benefits, eg a wider colour gamut, higher dynamic contrast ratios, higher brightness, etc over traditional CCFL backlit TVs.
Since the the main barrier to the wide use of LED backlighting on LCD televisions is cost, your C750 TV may well have been "half the price" and "left your wallet fatter" but to claim it is "just as good" is cleary wishful thinking!
