I have a Toshiba DST-3000 receiver, which I believe has a problem with receiving all of the local OTA HD stations. When I first installed my system, I had great reception for all the local channels, but now I only get NBC and KTLA. I've tried everything I can think of with the antenna and cables to confirm that they aren't the source of the problem, so I am fairly sure its the box. I'd like to confirm that it is indeed a problem with the box. Is there anyone in the L.A. area who would be willing to bring their HD receiver over some evening to see if they get a better signal? Preferably another Toshiba, but anything will work.
