8. Troubleshooting
If you encounter any issues with your Bobtot Home Theater System, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from speakers. |
|
|
| Bluetooth not connecting. |
|
|
| Sound distortion or buzzing. |
|
|
| Remote control not working. |
|
|
| System volume defaults to 45 after power off (not standby). | This is a known system behavior when the unit is fully powered off via the rear switch, not just put into standby. | Always use the 'ST.BY' button on the remote or front panel to put the unit into standby mode. This will retain the last volume setting. If you power off completely, be prepared to adjust the volume down quickly upon restart. |
| Cannot adjust individual front/surround speakers. | The system allows individual adjustment for Center and Subwoofer. Front speakers are adjusted together, and Surround speakers are adjusted together. | This is by design. Use the 'FRONT' button to adjust both front speakers simultaneously and the 'SURR' button to adjust both surround speakers simultaneously. |
If the problem persists after trying these solutions, please contact Bobtot customer support for further assistance.
