PROBLEM: The green LED doesn’t light up when I aim my remote at it.
SOLUTION: There are a few things that can go wrong here, so we will go from
the most likely to the least.
1
You forgot to turn on the power, or your DC adapter isn’t compatible (the
polarity is reversed).
2
You installed the green LED in backwards. Please check the orientation.
3
Your remote control’s battery is shot. Replace the battery.
4
Junior poured a coke and some ice cream into it. Take it apart and clean it
with warm water and a touch of dish detergent.
5
It is an ancient remote that has a hammer and chimes inside. Those just
won’t work, this is for IR remotes only.
6
You are trying to relay an IR remote that is modulated at some other fre-
quency than 38kHz. There are some other ranges available but 38kHz is
by far the most common. Most consumer components operate at 38kHz.
This product ONLY works at 38kHz.
PROBLEM: The LED stays constantly lit.
SOLUTION: The detector is too near the IR LED/ or a noise source is saturat-
ing it. The IR detector can become saturated and remain on, jamming the
unit. Reposition the IR LED to aim away from the detector or even use some
creative “shielding” tape to shield the input to the detector.
STILL HAVING TROUBLE?
While we had hoped that it wouldn’t come to this, if you are still having trouble
with your IR controller, here are a few additional suggestions.
Use a methodical, logical troubleshooting technique. Most problems can be
solved using common sense. A volt-ohm meter and a clear head are usually
all that are needed to correct any problem. Most problems are due to
misplaced parts and/or bad solder connections. Working backwards through
the assembly steps will often lead you to the problem. Revisit the extensive
theory of operation included in this manual and try to apply it to your specific
problem.
Have another set of eyes look at your work. Here at the shop we have often
run into a “stone wall” of a problem only to have a fellow technician see our
obvious error. It is sometimes very difficult to see your own mistake; taking a
break can often solve this common problem.
