Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's negative battery terminal using a socket set to ensure safety.

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse associated with the radio (refer to the owner's manual for the exact location).
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse; if it appears burnt or broken, replace it with an equivalent amperage fuse (typically 10A to 15A for the radio).
Reinstall the fuse and reconnect the battery terminal.

3. Check the Wiring Harness

Remove the radio unit from the dashboard (follow specific removal instructions for the Honda Accord).
Inspect the wiring harness connected to the radio for any visible damage, corrosion, or loose connections.
If damaged, repair or replace the wiring harness as needed.

4. Test and Replace the Radio (if necessary)

If the above steps do not restore power, test the radio unit by connecting it to a known working vehicle or power source.
If the radio does not power on, consider replacing the radio with a compatible aftermarket or OEM unit.
