Sonos Arc Soundbar F62 Fix: Error Code Guide

by

What This Error Means

F62 on a Sonos Arc basically means the soundbar is failing its startup/handshake check. The TV or Sonos app sees the Arc there, but it won’t fully power, register, or lock onto HDMI-ARC/eARC.

In plain English: the Arc is turning on wrong or refusing the HDMI link, so your TV can’t push audio to it.

Sonos doesn’t publish an official “F62” code for Arc, but if you’re seeing F62 tied to the Arc, treat it as a protection/boot fault, not a simple volume or settings issue.

Official Fix

Do it in this order. Don’t skip around.

  • Kill all power first. Unplug the Sonos Arc, the TV, and any HDMI switch/receiver from the wall. Leave them dead for at least 2 minutes so the protection circuits and HDMI-CEC cache fully clear.
  • Power the Arc clean. Plug the Arc straight into a wall outlet (no cheap surge strip, no smart plug). If the status light never comes on or stays stuck, you’re likely dealing with a hardware fault, not just F62 noise.
  • Swap the HDMI cable. Use a certified High Speed or HDMI 2.1 cable, 2–3 m max. Plug it into the TV’s HDMI ARC/eARC port only. No adapters, no daisy-chain boxes.
  • Hard-reboot the TV. With the Arc still unplugged from HDMI, unplug the TV from the wall. Hold the TV’s power button for 10–15 seconds (if it has one). Plug back in and let it fully boot to a TV channel or home screen.
  • Check TV audio settings. On the TV:
    • Audio Output: HDMI ARC or eARC.
    • HDMI-CEC: On (names like Anynet+, Simplink, Bravia Sync, etc.).
    • Digital Audio Out: Auto or Pass-through.
    • If there’s an eARC toggle: set to Auto/On.
  • Bring the Arc back online. Plug the Arc’s power back in. Wait for it to boot fully (steady white or whatever your normal idle light is).
  • Reconnect HDMI. Now plug the HDMI cable from the Arc into the TV’s ARC/eARC port. You should hear or see the TV detect it (some TVs pop up an “external receiver” message).
  • Use the Sonos app to re-do TV setup. In the Sonos app: Settings > System > [your Arc] > TV Setup. Walk through the prompts so the app and TV agree on the connection.
  • Update firmware. Still in the app, run a system update check. F62 popping during updates or first-time setup is often just outdated firmware or a half-finished update.
  • Test with everything else unplugged. Disconnect game consoles, streaming sticks, and sound devices from other HDMI ports. Run the TV with only the Arc connected. If F62 vanishes, one of those boxes is confusing HDMI-CEC; reconnect them one-by-one.
  • Last resort: controlled factory reset. Only do this if you’re ready to set the Arc up from scratch and ideally after talking to Sonos support. Follow the reset steps in the Sonos documentation for Arc exactly; don’t guess the button combo.
  • If F62 keeps coming back after all this, you’re probably looking at an internal power/amp board fault. At that point, it’s a support-ticket and warranty conversation, not a settings tweak.

The Technician’s Trick

When a Sonos Arc keeps throwing a mysterious F62 even after the official dance, this is how a working tech usually forces a clean HDMI handshake.

  • Isolate the Arc completely. Unplug every HDMI device from the TV. Leave only the TV and the Arc’s power cord connected (no HDMI yet).
  • Boot the Arc on network first. Power the Arc, wait for it to idle, then connect to it in the Sonos app over Wi‑Fi or Ethernet. Make sure it shows up in Settings > System and isn’t dropping offline. If it can’t stay online here, the problem is inside the Arc, not the TV.
  • Reset the TV’s HDMI brain. On the TV:
    • Turn HDMI-CEC and eARC Off.
    • Power the TV off, unplug for 1–2 minutes, then power it back on.
    • Turn HDMI-CEC and eARC back On.
  • Now connect only the Arc. Run a fresh HDMI cable from the Arc to the TV’s ARC/eARC port. No other HDMI devices yet. Give the TV 30–60 seconds to detect it.
  • Run TV Setup again in the Sonos app. Let the app program volume control and confirm it “hears” the TV. If this works with nothing else plugged in, the Arc itself is fine.
  • Add other HDMI gear back slowly. Plug in one box at a time (console, streamer, etc.). Power it up and test sound. If F62 or dropouts start only after a specific device, that box or its cable is killing the HDMI bus—replace it or move it to a different input.
  • Try a different wall outlet. If the Arc randomly shuts down or restarts when the TV or another device powers up, move the Arc to a different outlet (ideally another circuit) and bypass any suspect surge protectors. F62 that tracks power spikes is usually electrical, not software.

Is It Worth Fixing? (The Financial Verdict)

  • ✅ Fix: Still under Sonos warranty, or the issue clears with new HDMI/power cables or a clean setup. Premium bar, absolutely worth saving.
  • ⚠️ Debatable: Out of warranty, and a quote for board/power repair lands under ~40–50% of a new Arc while everything else is in good shape.
  • ❌ Replace: Repeated F62 plus random shutdowns, or any liquid/impact damage, and the repair quote sits near the cost of a new soundbar.
