For those of you who wish to be informed on finding hidden stations, I will share the secret. On your box, hold down select and exit together until the box displays "DIAG". Then once their you can tune to diagnostics on channel 611, or Discovery which is hiding on 280. Enjoy!
Each cable system headend no doubt has different settings. That SELECT/EXIT holddown lets me select diagnostics mode (Channel 1999 here) for the next channel tuned after 'DIAG' appears on my 3100HD LED panel. But HD channels can't be selected for diagnostic analysis following new channel additions some months back.
Not surprisingly, channel 280 is blank on NYC's TWC system. What's unclear is how to locate 'hidden' channels while in diagnostics. What page in diagnostics is used, and what can you read in diagnostics indicating it's Discovery in HDTV? Here, the Manhattan TWC system keeps the United Nations channel (78) hidden for some reason; it's not visible in the on-screen program menu, but tunes if you tap in "78." It's also one of the few switched analog channels, not 256 QAM delivered, from my headend.
So, was DIAG used to locate a hidden HDTV
Discovery on 280 or another channel, which was then tuned for normal HD viewing? Anyone else have success with this technique?
Here, NYC TWC just provided WB from WPIX-DT unannounced. It just appeared suddenly. There's no indication of Discovery HD in our HD channel lineup (701-714), although stories suggest TWC will add more HD channels soon. -- John
