Intermittent IR source
control
IR flooding
Check to see if ambient
light is shining on built in
IR receiver or in direct
line with plasma TV
noise. If the IR emitter is
flashing when IR is not
being sent, IR flooding
is likely cause. Disable
the built-in IR Receiver.
Consider use of an
external IR Receiver
(see Fig 2.2 and 3.2).
