Service manual:

1. Glass lid

2. Left aluminium plate

3. Release of sledge

4. Cover for chassis top plate

5. Chassis top plate

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.

How did you adjust L1 and L2 ?

Is it still possible to order a new ir pcb for mk1?
