Fatal Error - Gyro temperatures do not change

[David Vasquez]

Hello All; 

We have a fatal error in our  MP2028 which shows "GYRO TEMPERATURES DO NOT 
CHANGE" (right before this appears, "ADC GAIN INVALID" shows up for a 
second or two) in hyper terminal; and as "unknown error 36" in 
Horizon. we have tried everything including loading a new code and 
resetting zeros, but nothing seems to work. has anyone else 
experienced this? does anyone have an idea on what could we do? we 
have not been able to use our MP for some time now due to this. 

thanks in advance for your comments. 

Best Regards;

Gyro temperatures do not change: During the power on self test (POST), the autopilot checks to make sure the gyro temperature changes. If it doesn't that means there is something wrong with the gyro or connection to the gyro. Most likely the gyro failed. RMA the autopilot.

ADC gain invalid: The onboard ADC gain field(s) in your VRS are not set correctly. Fields 501-512, 566-569.
