Becker Car Audio & Video - Recent Questions, Troubleshooting & Support
Becker/BMW Indianapolis randomly turns itself off and sometimes produces cracking noises on the outputs while playing cd/mp3
The fact that you pulled it out of the car and tested it using a known good power source says more about your troubleshooting skills than most. Now you're ready to do the inevitable... tear it open. Open it up being mindful of internal connectors and possible ground leads coming from amp boards to the chasis. While there is likely no prints available for this unit for schmucks like us there are some very key things to look for.
1. Burnt components. Easiest to spot but hardest to identify. Hopefully there's another component nearby this one to help identify it. There are many online sources to purchase new components.
2. Deceased and bulging capacitors. Many electrolytic capacitors will swell up when they have given up on life. For safety reasons (preventing them from being a IED) the manufacturers have put little cross hatch cuts in the top to relieve the swelling when the electrolyte boils. This makes it easy to spot and caps are super cheap and easy to find. I do recommend getting one of exact value in the uH rating but suggest maybe bumping up the voltage (i.e. going from a 12vdc to perhaps a 16vdc). This will make them last longer in general.
3. Loose connectors. Give a little tug on each connection to see how much they're clinging to life.
