51 # 181473 Product: CD5 Subject: Micro Reset Modification Symptom: Customer complains of CD not working. Reason: CD micro is not resetting under certain conditions. Solution: Perform reset modification listed below to display PCB. 1) Remove: R408 (120k), C414 (1uf), R573 (270k), C547 (1uf), D502. 2) Add a jumper wire from the hot side of S416 to hot side of S502. This wire should not be excessively long, and should lay flat on the board. (See diagrams below) Note: Latter production units used an improved reset circuit (U404). U404 is located on the display PCB under the BOSE ¨ logo. This modification is not needed on these units.
52 # 177871-B1 Product: CD-5 Subject: Display Failure Symptom: Flashing VFD displays are being observed on CD-5 units. Reason: The existing ground trace breaks at the pad leaving no ground. This change affects PCB P/N 177400 and has been added to all production units starting the week of 12/17/95. Solution: Repair ground trace. 1. Refer to the disassembly/ assembly procedures to access the Digital PCB. 2. Compare the PCB to the figure below. If a piece of jumper buss wire is present from the VFD Support tab (closest to pin 21 of U402) to the ground trace, the modification has been done. If it is not present, proceed to step 3. 3. Scrape the ground trace a 1/4 from the VFD Support tab until the copper is visible. 4. Install a jumper buss wire from the VFD Support tab to the broken ground trace. Be sure to wrap the wire around the tab once or twice before soldering it to the ground trace.

Reason: Improper voltage rating on C19. Solution: Replace C19 with a 33uF, 63V capacitor, part number 149948-3301J. The display dims on some units, after the unit has been in use for a period of time. When a unit is returned from the field for service, C19 should be checked to ensure that the voltage rating on C19 is 63V. If it is not, it should be replaced with a 33uF, 63V capacitor, part number 149948-3301J. This should be done to all units returned for service to ensure this failure does not occur in the future. Refer to the schematic below, the CD5 service manual, part number 174798, and the CD5 supplement, part number 177871, for schematics, PCB layouts and disassembly procedures.
