basic troubleshooting tips for common problems. For issues not addressed in this manual,

Power and Signal Routing

Understanding power and signal flow through the display can help a technician 

troubleshoot an issue. 

Power Routing

Figure 11 

shows an example of how power is routed through the display.

1. 

AC Power enters the display through the power entrance box on the back of the 

display and travels to the Power Termination Panel.

2. 

Power is distributed to Module Power Supplies (2a), Player Power Supply (2b), 

Thermostat (2c), and Fans (2d).

3. 

DC Power is also supplied to the PLR (4) from the Player Power Supply.
