37. FAILURE – FAULT INDICATOR ON
38. FAILURE – RF UNLOCKED
39. FAILURE – OVERMODULATION
40. FAILURE – SELF TEST FAILURE
41. INVALID SETUP – CHECK SYSTEM BUS CONFIGURATION
44. If self test 11 passes, try to initialize a blank disc to further test the A2
disc drive.
OTHER TROUBLESHOOTING HINTS
42. Perform the unratioed power test for a1, a2, b1, and b2. Refer to
'System Maintenance, Troubleshooting' in the 8510XF Operating and
Service Manual, E7350-90001.
43. The A4 GSP and the A11 display must be working in order for a normal
display to be on the CRT.
45. A18 (85102) ANALOG TO DIGITAL CONVERTER TEST
When you first turn the instrument ON, if the noise on the trace is
greater than 1 dB, then the A18 board may be faulty.
If you cycle the AC power (Off, then On), the noise may disappear.
If it does, there is probably a malfunction with the A18 A/D board
although no apparent symptoms are present. There also may be no
Running Error Messages, Self Test Failures or Service Program test
failures.
36. DISC MEDIA WEARING OUT - REPLACE SOON
35. INITIALIZATION FAILED
34. DISC COMMUNICATION ERROR
33. DISC HARDWARE PROBLEM
If this trace noise disappears when the POWER is cycled, the test has
FAILED and the A18 board should be REPLACED.
