Prodigy Service Manual

READ THIS FIRSTUsing This Manual: A person who will be performing service work on the PRODIGY should use this manual in the following manner: Read the Safety and Overview Chapters to familiarize yourself with the scanner as a whole and with the general function of the circuit boards. Chapter 3 should be understood completely as it explains the Diagnostics Software (built in requires a password for access). The Chapter 4 and Chapter 5 contain common procedures and troubleshooting information and can be read as needed, but are good sources of information. When a problem arises, Chapter 4 should be referenced. Check the table of contents for Chapter 4 to see if the problem being experienced is described. If so, refer to the appropriate page. If not, try to generalize the problem (e.g. the Detector is repeatedly running into the front of the scanner and reversing and then running back into the front of the scanner. This is a mechanical problem in general, specifically with Transverse Mechanics, check that subsection of Chapter 4 for the subsystem experiencing the fault. This manual commonly references other Sections and pages of the manual as needed, so often procedures in the Chapter 5 Appendix are referred to as ways to solve problems described in Chapter 4.

Information Requested By GE-LUNAR: When requesting assistance from GE-LUNAR, please provide the following information: System Number (DF+xxxxx) Institution or Doctor's name Location Complete list of symptoms Names and part numbers of parts needed for service

In addition to the information above, an Error Log printout and QAs and QA history or other failing diagnostic test printout (Alignment Test etc.) will also help to improve the accuracy of our diagnosis: For problems with specific patient scans, it is recommended that you copy the scan files to diskette, and send it, with a description of the problem, to the Applications Department at GE LUNAR.
