Intermittent Problems

A problem occurs only

difficult to detect.
Verify that:
1. All cables and cords are securely connected to the
rear of the system and attached options.

the rear of the system at the fan grill. If there is no
air flow, the fan is not working. This causes the
system to overheat and shut down.

terminators.)
