Normal support procedures require that the TIM be shipped back to RI for repair. Contact [email protected] for RMA and safe shipping instructions.
Under certain rare conditions, it may be appropriate for the TIM to be opened and serviced on-site. All TIMs share the same case that can be easily opened for service and placed in use for diagnostics (attached to the Test Head) with the cover removed. DO NOT TOUCH any active electronics with the case removed without direct instruction from RI. TIMs can be safely removed from the Test Head with the power on. The software should be in an idle state (TestExec not running and no testplans loaded) and the Fixture should be removed prior to removing any TIMs.
IMPORTANT: The Fuse is soldered to the bottom of the Y00070X# board and so the bottom cover should be removed. The top cover can be left in place.
