PCB14 IR Receiver:
- Carry out points 1 to 5.
- Remove 35P53, power supply for sledge motor, and 26P96.
- Remove the screws for the top plate (C, D, E) (see under point 10), lift the top plate carefully (approx. 2 cm), and carefully pull the top plate a little to the right.
- Remove two screws for PCB14 and lift off the PCB.
If IR does not work probably C9 lost the capacity. I had to adjust the 455kHz L1 and L2 filters several times because they were not tuned.
