hey people i purchased this amazing plasam a few days ago, its great. now the isssue i have with it is that when im watching hd channels and then turn it to another hd channel it loses its signal!! though the non hd channels work fine, then i flick through the channels and the hd channels are back on!! Though sometimes they dont come back so i have to find the channels again??
Does anyone know what he problem is?? Could it be that it loses its signals?
P.S im from Australia if anyone is unsure what hd channels im talking about.
