A blown fuse in a house can look like a blackened or charred spot on the fuse itself. It can also appear melted or broken. To identify a blown fuse, you can visually inspect the fuse for any signs of damage or use a multimeter to test for continuity.
A blown house fuse may look blackened or have a broken filament inside. To identify it, check the fuse box for any fuses that appear damaged or have a visible break. You can also use a multimeter to test the continuity of the fuse to determine if it is blown.
Sounds like you have a blown fuse. Check the fuse box.
If your radio will not turn on at all then it is probably the fuse. Some speakers also have fuses too, if it wasn't a fuse then the speakers would probably sound torn. To check the fuse it depends on your car, look in the manual on how to change the specific fuse. Many modern cars have fuse boxes under the glove box on either the passenger or driver side. The fuse should look somewhat like a flat, transparent house plug, in the middle of the transparent plastic there is normally a connected wire and if it is broken the fuse is blown. If you have a fuse box you can compare with another good fuse or just look up an image of blown auto fuse.
Metal strip inside fuse will be broken or burnt
A fuse is used for protection. If you replace it with a nail, you give up the protection. If the fuse blew, there was a reason, and the fuse protected you from the results of what would have happened if it had not blown, like such minor inconveniences as your TV set getting blasted beyond repair, or your house burning down.
More than likely it is something as simple as a blown fuse and probably labled something like 'Gauges' or "Instr Pnl" in the fuse box. Check for a blown fuse.
If you can observe the fusible link it should be open and there should be some charring on the glass. Use an Ohm meter to confirm fuse is blown. If it is zero ohms across the fuse it is not blown.
It is likely that there is a blown fuse. Open the fuse panel as per your instruction manual. On the fuse itself, you will see what looks like a tiny metal band. If that band is not connected (i.e. the fuse is blown) it will need to be replaced.Otherwise it could be a short circuit somewhere.
Did you check the fuse box? Sounds like a blown fuse to me.

When an electrical circuit in a car fails, the most likely reason is a blown fuse. The owner's manual will contain a diagram of the different fuses, each circuit identified. Identifying the possible fuse, from the manual, and then looking at the fuses physically, will most likely show which fuse is involved. There is also likely, a fuse diagram within the fuse box showing where each fuse is. The fuse needs to be visually inspected. Good fuses will show a shiny metal link on top. Blown fuses will show a dark gap. Sometimes, you need to pull the fuse out of the socket and look at it through the light. You can then see the broken link clearly. Another method of finding blown fuses is by using a volt meter. Normally, the voltage across a fuse is trivial, but when a fuse has blown, the voltage across it will be around 13 volts. This is because the circuit has been broken and the full battery voltage is across it. For a tail light, the lights need to be turned on when checking the voltage across the fuse.
