In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!

Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

Sound Bar Disassembly Procedures

1. Top Cover Removal
1.1 Remove the 12 screws securing the top cover.
Important Note:
1. When replacing the top cover screws, follow the sequence in Figure to avoid causing the top cover to bow.
2. Ensure no wire harness obstructs a screw hole or gets pinched by the top cover when replaced. When removing any internal part, make note of the wire dressing and it ensure it is maintained after replacing a part.

1.2 Flip over the sound bar so the grille is facing up.
1.3 For CineMate 1SR version only, remove the AdaptIQ door on the left side.
1.4 Grasp the top cover at both ends and lift off.
2. Phase Guide Speaker Removal (Left or Right)
2.1 Remove the two screws securing the phase guide to the bottom panel.
2.2 Lift out the phase guide and remove the wire connector from the PCB.
Note: When replacing the phase guide, ensure the wire harness is wrapped along the back of the speaker and under the phase guide. For the right phase guide, ensure the wire harness does not extend around the AC PCB shield., Right Phase Guide Wire Routing.

3. Twiddler Removal
3.1 Perform procedure 1 first.
3.2 Remove the four screws indicated in Figure.
3.2 Lift out the Twiddler
Note: Make note of the wiring configuration for use when attaching a replacement transducer.
4. Front Tweeter Removal
4.1 Perform procedure 1 and 8 first.
Note: Removing the IR/LED PCB will release the tweeter harness. Make note of the wire harness routing and ensure it is properly wired under the IR/ LED PCB when replaced.
4.2 Remove the two screws indicated in Figure.
4.3 Lift out the front tweeter.
5. DSP PCB Removal
5.1 Perform procedure 1 and 2 (left phase guide) first.
5.2 CineMate 1SR - remove the AdaptIQ bezel by releasing the two snaps indicated.

5.3 Remove the cables from the PCB. Use a U.FL extraction tool, such as Hirose part number U.FL-LPN-2(01), to remove the U.FL connector. Use care when removing the U.FL connector to avoid damaging the connector.
5.4 Remove the screw indicated in Figure securing the DSP PCB.
5.5 While using care not to bend the RF antenna, lift off the DSP PCB.
Note: When replacing the DSP PCB, use care not to bend the RF antenna or damage the U.FL connector when reconnecting. Press gently straight down to insert the U.FL connector. Excessive or angled pressure will damage the connector. When properly installed, the antenna cable will rotate freely about the connector. Do not rotate more than 1/8th of a turn to avoid damaging the connector.

6. AMP PCB Removal
6.1 Perform procedure 1 first.
6.2 Remove the two screws indicated in Figure securing the Amp PCB.
6.3 Remove the wire harness connectors and ribbon cables from the PCB. Lift out the PCB.
Note: 1. When installing the Amp PCB, ensure the wires are properly dressed. Amp PCB Removal.
Note: 2. Avoid removing the metal heat spreader plate (located on the bottom of the AMP PCB). If it was removed, ensure a void-free thermal gel contact between the plate and the three IC location markings on the PCB. Reapply thermal gel if needed, Chromerics 65-00-GEL30-0010, Bose part number 369952-001S

7. I/O PCB Removal
7.1 Perform procedure 1 and 6 first.
7.2 Remove the three screws indicated inf Figure securing the connector backup and I/O PCB. Lift out the connector backup and I/O PCB together.
7.3 Remove the ribbon cable from the I/O PCB. Remove the U.FL connector only if needed. Use a U.FL extraction tool, such as Hirose part number U.FL-LP-N-2(01), to remove the U.FL connector. Use care when removing the U.FL connector to avoid damaging the connector.
Note: When replacing the I/O PCB, use care not to damage the U.FL connector when reconnecting. Press gently straight down to insert the U.FL connector. Excessive or angled pressure will damage the connector. Apply glue to the cable as shown in Figure to relieve strain on the connector. When properly installed, the antenna cable will rotate freely about the connector. Do not rotate more than 1/8th of a turn to avoid damaging the connector.

8. IR/ LED PCB Removal
8.1 Perform procedure 1 first.
8.2 CineMate 1SR only - lift off the mesh covering the IR/ LED PCB. Figure 13.
8.3 Remove the screw indicated in Figure securing the IR/LED PCB. Lift off the IR/LED PCB.
Note: It might be necessary to replace the mesh covering if the adhesive does not adhere when replaced,

9. AC PCB Removal
9.1 Perform procedure 1.
9.2 Remove the two screws indicated in Figure securing the AC PCB and insulator. Lift off the AC PCB and insulator
9.3 Remove the wire connector from the AC PCB.
Note: Ensure the AC PCB insulator is properly positioned over the AC PCB when installing. The open grove aligns with the opening for the top cover screw.

10. Power Supply PCB Removal
10.1 Perform procedure 1 and 2.
10.2 Remove the three screws indicated in Figure securing the power supply PCB. Remove the wire harness connectors and ribbon cables. Lift off the power supply PCB.
