Rec No.	Date	Loc From	Title	Loc To	Notes
200	2010-09-03	Factory	Disposed	Disposed	Report from vendor not repairable: s/n 000000573FAA Condition on arrival: Visual inspection shows only a missing pin (ID pin, which would not affect probe readings) and a very slight separation between epoxy and the plastic probe head. Ctrl ground and RF ground resistance checks fail, diode 2 resistance passes, but both diode 0 and diode 1 lines indicate an open circuit to one diode in each pair. Only 3 of the expected 5 diode waveforms observed in, probe scans fail (only 2 of 4 segments return values).
