Section 4: Maintenance & Troubleshooting
Important Notes:
• Turn off display power before performing any repair or maintenance work.
• Only qualified service personnel may access internal electronics.
• Dirt and contaminants may enter the display if it is operated without the fan filters in place. These
contaminants may cause premature failure of the electronic components. Operating the display with
dirty fans and filters will make the warranty null and void.
• Daktronics product managers' engineering staff must approve any changes that may affect the
display's weather tightness. This includes, but is not limited to, border shrouding, back sheets,
cooling fans, fan filters, and filler panels. If any changes are made to the display's weather tightness,
submit detailed drawings to Daktronics engineering staff for evaluation and approval, or the warranty
will be null and void.
