Symptom #3:
TB LED on IR Receiver (and/or Emitters) on solid
Cause
1. Plasma Interference
2. Voltage and Ground wires are
reversed at the connecting block
or IR Receiver
3. Relatively high levels of ambient
noise. This can be due to any of
the following: Sunlight, florescent
Lighting or Plasma Displays.
4. EMI induced noise. This can be
due to light dimmer controls or
other radiating electronic devices
(PC's or any poorly shielded
electronic device).
5. Power Supply not putting out
proper voltage.
Solution
Use a 85 or 95 series Plasma
'Friendly' Receiver. If already using a
this unit, please note the Plasma in-
terference can be reflected off of any
item it comes into contact with within
approx. 3ft. From the front of the dis-
play. Keeping this in mind, make sure
that the IR receiver is free from any
obstruction that might reflect back into
the receiving eye.
Recheck your wiring.
In this case use either a SUN filter
(SUNKIT), or any of our 'Plasma/
CFL Friendly' IR Receivers (DL85/95,
HL85/95, ML85/95, WL85/95). These
can also be used in direct sunlight
and in the presence of 'tube style'
fluorescent lighting.
Reposition IR Receiver and/or cabling
away from emitting device. You can
also place a 470Ohm resistor in
parallel with the IR Signal and GND
connections on the connecting block.
This will also help alleviate any stray
capacitance in the cable.
Verify supply is a 12VDC regu-
lated supply reading between 11.5 to
13VDC under load.
