Won't turn on after swapping
It sounds like a battery problem.
Check to see if the battery is installed correctly.
Take it out and put it in again, and see if it works.
Try a another battery that you know is good.
If you have any way of testing the battery do it.
If the crackling was happening before you changed the battery you may have another problem, otherwise a sick battery is more probable than the earphones dying at exactly that time.

I have a short in the right earcup, when tapped it
well you have a few options the first is how long have you owned the unit? is the unit still under warranty? if the unit is under warranty contact bose for a replacement unit.
the 2nd if its not under warranty is to open the bose headset and re-solder the right ear piece. If you can tap the right ear piece and the sound becomes intermittent that is a indicator that it is inside that headphone.
If you have a soldering iron and flux/solder Open the ear piece and then attempt to find the loose connection. At this point put a little flux on the the loose wire. Then heat up your soldering iron. Now only take a small bit of lead free solder and attempt to repair the loose connection. If you solder it correctly it should be working perfectly fine
If you need further assistance please feel free to follow up with a comment and i will be here to assist you. If this assisted you please feel free to rate the comment 4 thumbs up. thanks and have a great day.

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.
