The set top box is being controlled by
IR interference from other remotes or
IR emitters
Depending on the location of the set top box, the set top box may experience
interference from fluorescent lights, IR remotes or from other IR emitters on
set top boxes in the same area.
The IR emitter supplied with the PD295-002 allows the pass through of other
external IR signals through its outward facing side. This IR emitter also sends
the IR signal out the side opposite the cable entry, besides sending the
signal through the side mounted to the set top box.
Fluorescent lights emit IR noise that reduces the sensitivity of the set top box
IR receiver.
If there is a possibility that the IR emitter can be exposed to unwanted IR
signals in the area, it is recommended that the IR emitter be covered with
tape that blocks IR.
Set top box and TV are out of sync
Set top box is ON when the TV is OFF
or
set top box is OFF when the TV is ON
It is possible that the TV power state and the set top box power state get out
of synchronization; the set top box is off when the TV is on. To correct this
problem, turn both the TV OFF and set top box OFF.
If the problem persists, the IR emitter cable may not be aimed well enough
for the set top box to receive the proper signal. Try moving the IR emitter
and then covering it with black tape as suggested above.
TV turns on but does not control the set
top box. There may be only a black
screen or a fixed satellite channel that
cannot be changed.
There can be many causes including a locked up set top box, miswiring, or
incorrect configuration settings.
1. Reset the set top box using one of two ways.
a. Push the reset button on the set top box.
b. Remove power from the set top box for 30 seconds.
2. Check the wiring. The signal loop must be correct and complete. The
CCI cable from the TV must connect to the Interface Module which is
in turn connected by IR emitter to the STB that is sending
audio/video and optionally power to the same TV.
a. Visually verify as many connection points as possible.
Sometimes this is not easy, so proceed to the next step.
b. Verify all 3 LEDs are lit for the Interface Module that is
supposed to be connected to this TV. See “
Verifying and
Troubleshooting Connections
”. If they are lit there is certainly
a connection to a TV and set top box, but possibly not to the
correct devices.
c.
Turn on “Flash Intface Pwr LED” to identify the Interface
Module connected to this TV as well as the STB which is
being controlled by this TV. See section “Interface Module
