How do you get the radio to work again on a 97 Honda Accord v-tec?

Check the fuse.

If it is a factory radio , It would be best to take it to a dealer and get then to put in the security code for it

:

Remember, this car has two fuses that operate the radio, one behind the driver kick panel, the other in the fusebox under the hood.

When the car was new, the 5 digit radio code was supplied on a card with the owner's manual. Sometimes it can be found on a small white decal stuck to the back side of the glove box door. Worst case scenario, remove the radio, get the serial and model numbers from the top of the radio, and purchase the code online for $5.
