Maybe someone can help me. Myself and one other person on this forum have experienced vertical banding (purplish light scrolling through tv from right to left). I don't know if it is my tv or the dvr. It only appears on the HD channels, even when not broadcast in HD, and you can see it mostly at night or when room is dark. My tv is a sony crt 34HS510 and my dvr box is the Motorola dct6412III. I have it hooked up through hdmi with a dvi/hdmi adapter. It also appears when hooked up through component. I only have two months left on the warrenty for the tv so I need to know what the prolem is. Does anyone have an idea of what the problem can be and a fix? Thanks in advance.
