13-3-2 DMD Panel Pin Terminal Characteristics Diagram
※
Remove the heat sink attached to the DMD Board and tighten the screws in four places and then inspect the characteristics of
each pin terminal.
The vertical lines, which may occur due to improper connections between the panel and the
PCB, occur with intervals of 50 inches(26mm). If vertical lines occur with intervals of more than
26mms, it indicates a failure of the DDP1011 IC itself. If they occur with intervals of less than
26mm, it means that more than two pins have bad connections.
