AR900 IC209 failure
The AR900 has very few common faults. One of the few items that has been known to fail is IC209.
This is the main 5V regulator and will fail if there is a problem anywhere else in the set (failed IC or shorted track). It is a simple component to replace and is located roughly central on the middle PCB. The only problem with the item is that the correct device has to be used. This is a 2930L-05. A normal 5V regulator will not work satisfactorily.
AR900 RESET
The AR900 doesn't generally suffer from crashing of any sort. There is no actual reset procedure. If problems are experienced, then the only course of action is to remove all sources of power. Re-connection should restore operation. If problems are experienced, then a genuine fault will be present requiring logical fault finding.
