The TV remote or the cable remote? It often happens
that TVs won't respond right away, especially
if there is a lamp to warm up. But LCDs shouldn't
have that problem unless they are LCD rear projectors.
I was referring to the remote that works the cable box. With a cable box, the TV remote is secondary, usually only for set up. Apparently LCD's have the problem because of the backlight lamp that provides the illumination for the LCD panel. It requires a higher voltage during start-up, so IR emmisions then are high.
That's pretty interesting. Are you turning on
the TV, or the TV and the cable box?
I'm turning on both.
Uh, what exactly was that last sentence? When
you say you had no luck, you mean you moved the
TV with relation to the cable box, say, to another
room (it's easir to move the cable box for this
trial)?
I oriented the TV so the TV is at an angle to the room walls. The ratioale was that the IR emissions wouldn't bounce directly off the wall opposite the TV and back into the cable box which sits above the TV.
If the TV is spraying IR all over the room, the
only one of those solutions that might help would
be the layers of masking tape, but they might
kill IR reception, too. If the TV puts out the
same frequencies of light as the remote, blocking
one will block the other.
Remember that the remote is an active IR device and the IR from the backlight is reflected off walls so the stronger remote signal should override the weaker reflected IR noise if the geometry could be figured out. I haven't been able to make that work though, because the front of the cable box has a large window. So I would have to tape over the whole display. I'll keep experimenting.
