Once you have the boards apart, replace all the orange LED's, careful on polarity! I marked the positive side (long lead) with a red cross on the next picture showing finished job.
Now replace / re-solder the liquid displays and prepare the button assembly for reassemble as follows: Remove all the rocking buttons from the assembly and also its white plastic light reflectors (see picture). Attempting to re-assemble the button assembly without doing so is almost impossible.
This picture shows the triangle shaped metal contacts in place, ready to re-assemble in the boards. Just set the boards in top of the black button assembly and tight the screws.
This is the result before re-installing the white reflectors and the rocking buttons.
Install the reflectors and the buttons, then replace the front assembly in the head unit and install in the car.
