The answer to 'my electrical repair won't turn on' is that there could be several common causes, such as a tripped circuit breaker, faulty wiring, or a problem with the electrical component itself. Symptoms may include the device not powering on at all or intermittent power issues. Potential solutions could involve resetting the circuit breaker, checking for loose or damaged wiring, or replacing the faulty electrical component.
If you're comfortable with basic electrical work, you may be able to troubleshoot and fix the issue yourself. However, for more complex or dangerous electrical problems, it's best to call a licensed and experienced electrician to ensure the repair is done safely and correctly.
