Hello,

Thanks for coming to Fixya with your issue.

Allow me to try and understand your issue fully does the TV change size when you switch to a HD channel?

What happens is if a channel reception is interfered with, or the signal is too low to produce a HD channel you size will go from HD to standard DEFinition.

Now if the signal is good ether from the cable box or from the antenna then we are talking a decoder issue. So I need to know as far as clarification goes.

1. When does this happen
2. Does it happen on all channels

Thanks for your questions please do update me with more information so I can get back to you with a positive in depth answer.
