Subject: Incorrect IC identified in Self-diagnostic instructions of the service manual. Symptom: (xxxx)
Date: January 30, 2001
The IC identified in Self-diagnostic instructions on the CD-ROM issued with the Service Manual is incorrect.
Solution:
The Service Manual incorrectly misstates the potential cause of vertical deflection (V-Stop) as IC502. Please update self-diagnostic test indicator table on page 4 of the AA-2U Service Manual, as follows:
Probable cause for stoppage of vertical deflection (V-Stop) is that IC561 on the "A" Board is faulty.
