Toshiba Regza blank after tuning ''poisoned'' channel

My Toshiba Regza HDTV (model 37HL67S) has worked fine for over a year.
Now, after I tune to WFMZ-HD (channel 69-1 in Allentown, PA), the video goes black with no sound for -all- channels.
The AV inputs still work (video/sound from VCR and DVD) and the on-screen displays still work (channel numbers, menus), so it is -not- the backlight or anything like that.
Turning the set off briefly then back on does -not- fix the problem.
Tuning to a ''good'' channel, then turning the set off for about 30 seconds to a minute, then back on -does- return the set to normal operation.
Tuning to 69-1 recreates the problem every time.
This did -not- start happening with 69-1 until mid February (17?).

Firmware is HL07S 3.3.66.0 dated Aug. 23 2007 14:31:23 FW 32.

My Samsung HDTV set (tied to the same whole-house antenna) tunes 69-1 just fine. I am only receiving broadcast signals--no cable or FIOS boxes in the way.

SOURCE: trouble tuning in empty dtv channels

Just go to the main settings. You will see an "autoprogram" option. Select this and it will scan all available channels and delete non-airing channels
