If it turns on and goes off each time you turn the car on, it is not the fuse. If the fuse were blown, it would not turn on at all. Based on what you have told me it sounds like a capacitor in the power control circuit has gone bad.

That number is the signal strength indication. IF you get four beeps when that shows up and it could be E instead of 8, the unit has detected something wrong.

The outside diameter of the power ports in cars varies slightly. If there's too much "slop" between the port and the plug, you'll have the indication you're seeing. Try wedging a some card board or similar between one side of the port and plug to help keep pressure on the side contacts - and keep the plug from falling out of the port.

You may even wish to hard wire the detector to your car's switched accessory terminal. This will remove the power port from the the equation and the detector will turn off when the engine is off, and automatically turn on when the engine is running.

Good luck!

I have a Cobra ESD-9117 that wouldn't turn on. There was power at the plug end. I took it apart and took the power/volume button off. I used a magnifying glass and found the contact for the power must have bent from all the years of use. I bent it back and all is good again.

Maybe the fuse for the accessory port / cigarette lighter is blown. Check the fuse map for your car and confirm if the fuse is good or not. Or, if you have another device that uses the port, plug it in and see if it gets power.
