Bose L1 Model II System Single Bass Package with T1 Audio Engine Questions & Answers
No sound out of tower
Try different inputs. Connect your output to a different amp to check there is a signal there. Sorry to suggest this but often it's a simple solution, check carefully that all controls - volume etc - are turned up enough. Check the two parts of the tower and where it connects to the base are connected properly
Pyle P22-03ABTU stereo receiver.
Question edited for clarity. It is a 'Pyle' not a 'Pile'.
It is under warranty. Return it, an internal component has failed probably an electrolytic capacitor.
One thing you can try is to disconnect it and move it to another room to discount EMF from something.

Bose wave radio doesn't turn on with the remote but one time in 20 to30 times pushing the power button.
You can check with new battery in the remote. Next you point a digital camera, a smartphone should do fine, at the infra red transmitter on the front of the remote and then look on the camera screen if you see the ir light flash different pulses for each button. Infra red light can not be seen but a digital camera shows it really well. Confirm this with another remote. Now you know if the remote functions right. Remotes are available on-line or one can use a universal type remote. The IR receiver is often welded onto the circuit board. This means that it is not right behind the front panel window. It can be obstructed, perhaps by dust or displaced. This is generally speaking.
Bose lifestyle 18 have rapid loud hum when plug to power supply and no led light on the subwoofer.
If you've replaced the LM4766 ICs and the humming sound returned, there could be a few possibilities to consider:
- Grounding Issues: Humming sounds in audio systems can often be caused by grounding issues. Ensure that all components are properly grounded and that there are no loose or disconnected grounding connections.
- Power Supply Problems: The rapid loud hum could be related to power supply issues. Make sure the power supply is stable and within the correct voltage range. Also, check for any issues with the power cables or connections.
- Filter Capacitors: Check the filter capacitors in the power supply section and around the LM4766 ICs. Faulty or aging capacitors can lead to noise issues in audio systems.
- Signal Interference: Electrical interference from other devices or cables can sometimes cause humming sounds. Make sure the audio cables are properly shielded and not running too close to power cables.
- Speaker Connections: Double-check all speaker connections, ensuring they are secure and properly connected. Loose or damaged speaker wires can lead to noise issues.
- Board-Level Problems: There could be other components on the circuit board that are causing the issue. Inspect the circuit board for any signs of damage, burn marks, or soldering issues.
- Magnetic Interference: Make sure there are no strong magnetic fields or sources of interference near the system that could be causing the humming sound.
- Professional Help: If you've exhausted your troubleshooting efforts and the issue persists, it might be best to seek the assistance of a professional audio technician who has experience with Bose systems. They can perform more advanced diagnostics and repairs.
Remember that working with electronics and audio equipment requires technical expertise and can involve risks, including electrical hazards. If you're not comfortable or experienced with electronic repairs, it's advisable to seek professional assistance to avoid potential damage to the equipment or harm to yourself.
