SOURCE: how do you replace the meter light in a cobra 25?
You need to open the unit up ( remove the case/cover). Then remove the 4 screws holding the face plate on. Remove all the knobs ( they slip off) . remove any screws holding the meter on ( there may be none depending on which model you have ) . slide the meter out of the face plate and replace the meter with a new meter. Note: The meter light needs to be reistalled in the new meter. It simply slides out the side of the old meter and slide back in the new meter. Replace all the screws, and the jobs completed.
Good Luck and a good weekend to you.

The Cobra 25 requires the mic to be working for any sound to come out. My suggestion is that you first try a new mic. If this doesn't work, look real close at the board on the soldered side ( around the if section, thats the area that right under the waxed area on the component side of the board ) for cold solder joints ( broken lead solder) You may need a magnifing glass. Good Luck

turn your squelch all the way counter clockwise and your rf gain clockwise. If that doesn't help, try hooking up an external speaker to make sure its not the internal speaker. If these help or don't help, please reply on this thread to let us know, so we can give you more advice if needed.

You most likely blew a Diode that is back near the power plug.
It is easy to fix the diode but if you continued to apply power you may have damaged other parts including the audio chip.
