Solution

1. Preparation

Gather tools: multimeter, fuse puller, socket set, and flathead screwdriver.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Use a fuse puller to remove the radio fuse and inspect it visually.
Replace the fuse if it is blown with one of the same amperage.

3. Examine Wiring Connections

Remove the radio from the dashboard using a flathead screwdriver and/or socket set.
Carefully inspect the wiring harness for any loose connections or visible damage.
Reconnect any loose wires and repair or replace damaged cables as necessary.

4. Check Power Supply

Use a multimeter to test the power supply wiring to the radio.
Ensure that the radio is receiving a stable voltage (typically 12V).
If there is no power, trace the wiring back to the fuse box or battery for further inspection.

5. Reinstall Radio

Once all checks and repairs are made, carefully reinstall the radio back into the dashboard.
Reconnect the negative battery terminal.
