My tv is four years old (Sansui, 32"). There is a faint "comb" of the display in the top 1.5" of the display. The kids bought a cable to attach their iPod to the tv; ever since hooking that up, this horizontal "comb" is there. Does that make sense?? Could a cable cause such a problem (they bought it over ebay from China)?? Is the problem reversible, or are we permanently with this display problem??
