Bedroom TV is Samsung 32" LED. Kitchen TV is Apex 32" LED. The Apex also
has poor volume, and I have to keep it turned up to "70"+ or so to get a reasonable sound level. According to info I have found, the Apex TV is a bottom of the line piece of equipment. I switched input coax from one TV
to the other with the same results. I put new coax in and it made no difference. The only thing I have not done is to put another TV in place of the Apex and see if I can get the crappy channels to work. Yes- channels 7.1 - 7.3.
