Check the ground signal for the right-hand picture. Check the cable between the control module terminal #A18 and display screen terminal #8.
Checking the supply to the display screen
Check the supply to the display screen. Supply is carried via a cable between control module terminal #A16 and display screen terminal #6. The ground terminal is from control module terminal #A13 and display screen terminal #3.
Checking the lighting for the control module
If the surround lighting for the display screen does not function. Carry out the checks as above on another cable.
Check the supply to the lighting. Check the cable between control module terminal #A20 and display screen terminal #10. The voltage must be approximately 10-14 V.
In addition check the power supply for the cable, the cable between control module terminal #A19 and display screen terminal #9. The resistance must be less than 1 Ω.
