Hey everyone
I have a digicorder (live TV) laying around from an old TV provider.
I have recreated the schematics for the front PCB, which drives:
- a 4 digit 7 segment display
- 9 Buttons
- 5 leds (2 bicolor)
- an IR receiver
By making these schematics, I saw a strange part in the circuit, which I don't quite understand.
The Ir sensor is connected using 3 resistors. Like so:

Do anyone of you know why its done like this?
thanks in advance
