100 Corporate Drive Mahwah, NJ 07430 Service Bulletin No. : OST-F1167 Date: April 25, 2007 _____________________________________________________________ Model: AVR-2106, AVR-886 Subject: Repair of the DSP PC Board. Symptom: The DSP section does not operate where the audio signal input is there but there is no output. In some cases the cause of the failure is the crystal oscillator on the DSP P. W. Board not oscillating. Solution: The following parts have been changed so that the oscillation can be stabilized. 1) The oscillator element (XTAL2: 25MHz) on the DSP P. W. Board. 2) The C842 and C847 capacitors (from 22pF to 10pF). This countermeasure should only be applied when needed. Parts: Ref# Description Part Number XTAL2 XTAL (25MHz) 00D 399 0951 004 C842, 847 10pF
