Keith

If you have the receiver in a tube to prevent oblique stray IR hitting it,
you may still be getting IR from the screen bouncing off an opposite wall
straight back into the receiver. I had a very similar problem with a plasma
screen.

I fixed it by attenuating the IR reaching the receiver by sticking a piece
of brown plastic packing tape over the receiver and then colouring it with
a
permanent black marker. Sounds a bit bizarre but I picked this tip up
elsewhere and tried it out and it worked for me. The tape alone didn't do
enough and you can experiment with the marker. I found that it didn't
noticably affect the strong remote control IR (from a Pronto in my case
which is pretty powerful) but knocked out the interference from the screen.

Regards

Richard
