the IR from the backlight is reflected off

the weaker reflected IR noise if the geometry
could be figured out.
I guess. The problem as you are experiencing it is that the reflected signal is strong enough to interfere with the remote control signal. What makes you think the reflected signal is weaker than the remote control signal? If the reflected signal is much weaker than the remote signal, the layers of tape might work...you should just try it out. Heck, it's a cheap fix.
I once accidentally cured a similar problem with blue painter's tape that I actually thought would kill all IR but happened to pass it pretty well.
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.
You could put some actual black plastic over the window around the sensor and cut down the amount of window that will transmit IR through to the sensor.
