I have a Westinghouse 42" LCD with NTSC/ATSC/Qam tuners. I am hooking my cable directly into the TV without a cable box. I was able to get about 40 digital channels along with about a dozen HD channels in addition to the analog channels. A couple of days ago, all of my digital channels including the HD are blank. No snow just a blank screen. No audio as well. Is this a cable problem or a TV problem? I autoscan and the tv picks up the digital channels but when I switch to the channel just a black screen. The analog channels are still working fine. Any help would be appreciated. Thanks.
Your box might be in broadcast mode. Please reboot it. If the issue still exists, your signal level is not within range. Please call customer service if that's the case. They'll will need to schedule a technician to come to your house.
I found out that the channels numbers were changed. I did an auto-rescan of channels from the TV and the new channels popped up. For example KTLA Channel 5 used to be 54.1 now it's 5.1. Thanks for the help.
