Williams Stargate Instruction Manual

							9DIAGNOSTIC PROCEDURESDiagnostic procedures are controlled by the AUTO-UP/MANUAL-DOWN and ADVANCE switches on the coin door.ROM TestSet the AUTO-UP/MANUAL-DOWN switch to the MANUAL-DOWN position and depress the ADVANCE pushbutton.A ROM test is performed and any ROM failure is first indicated on the ROM Board 7-segment LED display and then on theCRT screen as described in the Power-Up and Reset Tests text.RAM TestWith ROM test results present on the CRT display, depressing the ADVANCE pushbutton initiates the RAM test. If a RAMfailure is detected, it is first indicated on the 7-segment LED display on the ROM board and then on the CRT display asdescribed in the Power-Up and Reset Tests text.  Test scanning will continue if no failures are detected; depress theADVANCE pushbutton to terminate the test and the CRT display will indicate that no failures were detected.CMOS RAM TestWith RAM test results present on the CRT display, depressing the ADVANCE pushbutton initiates the CMOS RAM test.  Ifthe test is passed, the 7-segrnent LED display on the ROM board will read 0 and then the CRT display will read CMOSRAM TEST PASSED.  If a CMOS RAM failure is detected, the 7-segment LED display will read first 3 and then 2.then 3 and then 2, and after these displays the CRT display will read CMOS RAM FAILURE.  In this case theCPU/Video Board needs to be replaced.  If an interlock failure is detected, the 7-segment LED display will read first 3 andthen 1, the 3 and then 1 and after these displays the CRT display will read CMOS INTERLOCK FAILURE.  If thereis an interlock failure detected, first check out all connections to and from the interlock switch including the switch itselfand if all of these items check out then replace the CPU/Video Board.SOUND TestWith the CMOS RAM test completed. depressing the ADVANCE pushbutton initiates the Sound test. At this point the 5basic sounds of the game are cycled through automatically.  Each sound is labeled a SOUND L1NE by the CRT display.If more than one SOUND LINE produces the same sound, check all cable connections to and from the sound board.  If allconnections check out, replace the sound board and/or the ROM Board and repeat the SOUND test.SWITCH TestWhen the SOUND test has been completed depress the ADVANCE pushbutton to enter the SWITCH test.  During this testthe CRT displays the name of each switch as it is closed and blank out the name of each switch that is open.  The AUTO-UP/MANUAL-DOWN switch is spring loaded to always be in the AUTO-UP position (closed) and therefore will always beprinted out on the CRT display.  Operate all player panel and coin door switches being sure to operate the ADVANCEpushbutton last, as, when this switch is operated the COLOR RAM test will be entered.  If any switch that is operated doesnot show up on the CRT display. check out all connections to and from the switch for continuity and check the switchcontacts for cleanliness.  If all cabling and contacts check out, replace the ROM Board for coin switches or the InterfaceBoard for player panel switches and repeat the test. 
						

							10Color RAM TestWhen the SWITCH test has been completed, depress the ADVANCE pushbutton to enter the Color RAM test.  At this pointthe CRT display starts cycling through 8 different colors, dark red, red, light red, dark green, green, light green, dark blue,and blue.  If any of these 8 frames have a vertical band through them, this indicates a Color RAM fault.  To clean up orget rid of any vertical bands, replace the CPU/Video board.Monitor Test PatternsFrom the Color RAM test, depressing the ADVANCE pushbutton initiates the MONITOR TEST PATTERNS by placing aform of a CROSS-HATCH pattern on the screen.  This pattern can be used to check and adjust the color convergence of themonitor. After the convergence is as desired, depress the ADVANCE pushbutton and the CRT display goes to a red colorpurity adjustment display.  Depress the ADVANCE once more for green purity adjustments and once more for blue purityadjustments.  Finally, depress the ADVANCE pushbutton and the CRT display should be a color bar pattern of (from left toright): red, green, blue, black, white, yellow, cyan, and magenta.  With the completion of any and all monitor adjustmentsdepressing the ADVANCE pushbutton initiates the transfer to the BOOKKEEPING TOTALS display.For ease in monitor adjustments, the monitor may be slid back and the screen viewed in a mirror.  Remove the two bolts andcarefully slide the monitor back in its shelf; secure the monitor in the extended position by inserting the two bolts throughholes in the monitor base and monitor shelf provided at the left side of the monitor.Auto Cycle Mode1.From the color bar pattern (or from game over with the switch set to AUTO-UP) depress ADVANCE two times todisplay Game Adjustments page l.2.Hold the joystick down to advance to the second page of game adjustments.3.Position the cursor on AUTO CYCLE with the joystick and depress FIRE.4.Depress ADVANCE.5. The system will now sequence through ROM, RAM, and CMOS RAM tests repeatedly.  The coin door must be openduring Auto Cycle test.  If an error is detected, the test is terminated and the failure indication is displayed on the CRT.6. To terminate the Auto-Cycle test, turn the game OFF and ON.
