On Saturday I bought an HDTV (Toshiba 46HM95) that's DCR with ATSC/QAM tuners. I only have standard analog cable with Time Warner Austin.
When I set up the TV by plugging the cable directly to ANT 1, I naturally got all the standard lower tier analog channels AND I also (way up in the 400-500 range) got at least 4 local HD channels. The Toshiba also has built-in TV Guide. From Saturday afternoon through Sunday afternoon, all was good.
On Sunday night those HD channels suddenly had picture only--no sound.
Last night (Monday), those HD channels now had sound but no picture.
Same thing this morning (Tuesday). HD channels have no picture, just sound.
What changed? The only thing different is that the TV Guide listings finally updated sometime on Monday.
I get all the other standard channels just fine.
Anyone have any ideas? I'm new to this stuff so bear with my ignorance.
