One HD channel problem

[lito]

I have a problem where my ABCHD feed from Melrose, Mass. with pixelation and totally not showing.  It doesn't happen on the other HD channels.

Meanwhile it's okay on my other HDtv in another room.

Does anyone have an answer?

Are you connected directly to the TV, with a set top box, or with a TIVO?  The answer could be different depending on the connection method.

thanks for the reply.

i'm connected to an hd setupbox.

it's weird that only that channel is messed up.

i'd appreciate any suggestions as to what to do.

Have you tried changing the cable from the wall to the STB? If that doesn't help,  you could try swapping HD boxes between the locations.  This would indicate if it is a signal problem (bad connectors, splitter, or something similar) or a STB issue (less likely).
