How to eliminate hum or noise from my Sony STR-DE485?
- JJames WhiteSep 5, 2025
To eliminate severe hum or noise from your Sony Stereo Receiver, check that the speakers and components are securely connected. Ensure connecting cords are away from transformers or motors, and at least 3 meters from TVs or fluorescent lights. Move your TV away from the audio components. If the plugs and jacks are dirty, wipe them with a cloth slightly moistened with alcohol.
