Incorrect Mounting Damage
(KDT5000 and ADM840) produced prior to February 2005
When mounting the MDT, if the shield and metal spacer are not used the mounting screws may damage the bottom of the printed circuit board.
The symptons when this occurs is the display will either be completely black or blank, or in some cases may not power up.
This image shows a pedestal mount used without the shield and spacer.
This image shows the damage caused by the screws. The circles are where the screws cut into the board, note that the only one that really causes a problem in the screw in the upper right corner.
To repair two red wires are added to bypass the damaged circuit.
