Include problem with the control. Warranties to repaired section only.
Common Failures
One of the main issues reported for this product is an "Amplifier 4 Over Temp Error" that appears on the front panel upon power up. This error prevents the simulator from functioning when this card is installed.
Repair Approach
Initial diagnostic testing involves checking all outputs and applying power supply voltages. These tests typically show normal conditions with no current draw anomalies. However, the error may persist, indicating an issue that requires further evaluation.
Testing & Quality
Testing includes examining voltage and current draw levels during burn-in testing. In some cases, further testing may not be possible due to equipment or procedure limitations, which can lead to a "No Fault Detected" (NFD) result in certain areas of the circuitry.
