Well one hdmi cable does not differ from another aside the version number, and passing 3d or ethernet via the cable if the device supports it. But as far as your hdmi cable vs the techs, there is no technical difference between the two.
Imo you have either a defective box or possibly a defective cable, if both cables show the same poor pic quality then its most likely the box, if the box has already been changed, then your down to the tv or settings on the tv.
I know its not what you wanted to hear, but unfortunately facts are facts. Do you have any other components hooked up to the tv? Bluray,ps3,xbox etc? How do they look.
Also keep in mind there is only so much a tech can do about picture quality in general, signal aside, we are not trained nor authorized to calibrate tvs. Sounds like your tech did quite a bit to help you out, i hope he can get things resolved.
