Daktronics C44 - Manual (Page 52)

4-4 Maintenance &
Troubleshooting
To replace the boards inside the tree, first remove the front cover by removing the eight
screws securing it to the tree. Then, remove the single screw at the top of the board and
remove it by pulling it straight out of its socket. Install the new board by reversing the
procedure. Be sure to reinstall the screw holding the PC board in place before plugging the
tree back in.
A 20-amp fuse is located at the rear of the tree. If it blows repeatedly, do not change the
rating. There is a problem with the PC boards or internal wiring.
