Most likely the speaker simply blew due to excessive heat. This is a fairly common problem with all makes and models of radar detectors. Contact Cobra. They should either be able to send you a replacement speaker which you can install yourself, or they should issue you a RMA so that you can send in your Cobra for service.
There are 2 options for power plugs that can be purchased from Cobra for the 757. The straight 12V power cord is listed under item number: 420-030-N-001 and the coiled 12V power cord is listed under item number: 420-026-N-001. Both can be purchased from Cobra by calling their order line at: 773-889-3087 or visiting www.cobra.com
Sounds like an internal fuse going. Did it happen while you were starting the car? Could be a surge.... How old is it, if you cant return it under warranty (may not be covered if they say its your fault) you can open it up carefully and check for fuses or blown components like resistors/capacitors etc
I called cobra support(777-889-3087) and it was around $6 plus shipping for a replacement speaker. the correct phone number for cobra support is 773-889-3087 and can be found on their website.
Cobra was very courtious and I also got my replacement speaker for my XRS-9500.!
I had the same problem. Took mine apart and glued the broken piece back with Gorilla glue. Been working great, even in the Texas heat for 4 months now.
