Question about Toshiba 57H94 57" Rear Projection HDTV
There are many variables here that could cause the problem. I can receive a few local HD channels ( within about 60 miles ) on my 57H94. I am not aware of any "HD specific" settings- it's all part of the receiving circuits in the TV. The first thing I would look at is to be sure you have a secure antenna connection. Then be sure you have selected the correct antenna input on the TV (there are two). HD channels, as an example will show up as 10-1, 10-2, etc. Most TVs have different sensitivity thresholds, regardless of size. Usually digital signals, including HD, are either there or not. In most cases if a TV picks up a decent analogue signal, a digital set should receive the digital signal, including available HD channels, as well. If you are going to use an antenna, rather than cable or satellite, try to get the best antenna you can afford, that will meet your physical requirements ( indoor / outdoor,etc.). Keep in mind that not all digital TV signal are HD. All of our local stations in this area transmit a digital signal, but true HD broadcasts remain variable. I hope this has helped in some way-Good Luck!
