all required foams are present on the display panel,
–
no foam is damaged,

each foam is placed at the right location (and with the
right angle),
•
Make sure the EMC foams on the SSB shields are not
damaged and correctly mounted.

Insert all screws at the original position.
•
Make sure that all cables are placed and connected in their
original position.
