fuzzydog Posted May 30, 2022 Share Posted May 30, 2022 My old 2nd hand B&K AV5125 has developed a glitch. It will turn on and work for a few moments before shutting off. When this glitch started occurring the amp would work for longer periods of time before shutting down. The working duration shortened over time and now it basically shuts down immediately. Has anyone experienced something similar and know what might be the cause? Thanks 1 Quote Link to comment Share on other sites More sharing options...
billybob Posted May 30, 2022 Share Posted May 30, 2022 Hello, have you checked the inside for accumulated dust or other? Thanks! Quote Link to comment Share on other sites More sharing options...
fuzzydog Posted May 30, 2022 Author Share Posted May 30, 2022 No I haven’t cracked open the chassis yet. Is there a particular location where dust can cause a short? Thanks for your reply. Quote Link to comment Share on other sites More sharing options...

Thanks for your reply. Just an in general comment as unit may be experiencing heat buildup. Ventilation likely a suspect to eliminate. 1 Quote Link to comment Share on other sites More sharing options...
billybob Posted May 30, 2022 Share Posted May 30, 2022 And along with the just saying. If you do crack it open, you could take a photo of interior as the sharp members might spot a problem like cracked solder joint for example or an overheated part that has gotten worse.
