Replacing the CPU Board
The CPU board in the TLS-HLD must be replaced when:
• A system self-test failure occurs during a warm or cold boot, or
• The display contains garbled messages and/or the voltage between the GND and 8V test points on the back of the
CPU board is within 7 - 9 Vdc; or,
• The voltage between the GND and 5V test points [Figure 19] on the back of the CPU board is not within 4.75 - 5.25
Vdc.
1. Turn Off power to the system.
