Section 4:
Maintenance and
Troubleshooting
Important Notes:
1. Disconnect power before any repair or maintenance work is done on
the display
.
2. Qualified service personnel must make any access to internal display
electronics
.
3. The Daktronics product manager’s engineering staff must approve any
changes that may affect the weather tightness of the display. This
includes, but is not limited to, the border shrouding and back sheets. If
ANY modifications are made to the weather tightness of the display,
detailed drawings of the changes MUST BE submitted to our
engineering staff for evaluation and approval or the warranty will be
null and void
.
4. Care must be taken when handling the display’s face panel to prevent
injuries or damage, especially in windy conditions
.
4.1 Weather
Stripping
To ensure that the display is waterproof, weather stripping has been provided around
the entire display and around the face panel. It is important that the weather stripping
is installed properly at all times. Otherwise, water may leak into the display and
damage the components.
4.2 Module Numbering Convention
The following table shows the typical module numbering convention for a 16x64
display. A module is eight (8) pixels high by 16 pixels wide.
A101 A102 A103 A104
A201 A202 A203 A204
·
Labeling reference begins with the upper left module and increments to the
right and down from that point, independent of display size.
·
Modules are designated by the prefix “A.” A101 represents the upper left
module.
·
The hundreds digit indicates the module line number. A101 through A104
make up the first module line, A201 through A204 make up the second line
and so forth.
