Mark,

I received your letter with the ir sensor yesterday morning. So it toke less than 5 business days! Not bad.

In the meantime I replaced the faulty ir receiver and the remote works now as expected!
But I'm a bit confused. I always thought the ir sensor is the part in the most right position on the display board (the one that looks like two cut LEDs). But it learned that the ir sensor is the thing on the left side of the blinking LED. What ist this other part for?

Thanks Mark!
