Sony Bravia not discovering devices on HDMI, Wi-Fi, Bluetooth or USB — causes and fixes

Technician avatar Technician
Hey! We’ll figure out why your Sony Bravia is not discovering devices and get HDMI and wireless inputs working again. A few quick questions so we don’t guess:
• Exact Sony Bravia model (KD-, XR-, XBR-, etc.) and roughly what year you bought it?
• Which devices are not detected: PS5 / Xbox / Apple TV / Fire TV, cable box, soundbar, Blu-ray player, USB drive, Bluetooth speaker or headphones, phone for screen mirroring?
• On HDMI, do you see “No signal”, “Unsupported signal”, or just a black screen even though the device is on?
• In the TV menus, are devices missing from the Input list, Bravia Sync device list or Bluetooth device list?
• Did anything change recently — firmware update, new HDMI cable, new soundbar, moved the TV, or factory reset the set-top box/console?
The more detail we have, the better we can solve a Sony TV not detecting devices on HDMI or Bluetooth instead of randomly unplugging things.
Customer
It’s a Sony Bravia Android TV from a few years ago. My PS5 and a soundbar are on HDMI 1 and HDMI 3 (ARC). Yesterday the TV stopped recognizing HDMI devices. It just shows “No signal” or a black screen, and in the Bravia Sync device list it says “No devices found”. I also tried a Chromecast on HDMI 2 and the TV doesn’t discover that either.
Technician avatar Technician
Got it — that’s a classic Sony Bravia HDMI not detecting devices situation.
A few common reasons why a Sony TV won’t discover HDMI devices:
• The TV or device got stuck in a bad HDMI handshake (HDCP copy-protection glitch) after a power cut or update, so the TV shows “No signal” even though the console is on.
• Bravia Sync (HDMI-CEC) or the HDMI input gets disabled, so the TV doesn’t auto-discover devices or list them in the Bravia Sync menu.
• The HDMI port mode changes (e.g., “Enhanced format” for 4K/120 Hz) and an older device can’t output a compatible signal.
• Less often, a cable, port, or soundbar pass-through fails so it looks like the Bravia is not discovering any devices.

We’ll:
1) Do a power reset of the TV and devices to clear the HDMI handshake.
2) Check the External Inputs and Bravia Sync settings so inputs can be discovered again.
3) Test each HDMI port with a known-good cable and device.
Once HDMI is stable, we can also check if your Bravia is not discovering Bluetooth or Wi-Fi devices like speakers or casting devices.
Customer
I’ve already unplugged the PS5 and soundbar a few times, but the TV still says “No signal” on HDMI. Sometimes the PS5 logo flashes for a second and then the screen goes black again. How do I properly reset the Bravia so it actually detects the devices on HDMI?
Technician avatar Technician
Perfect question — a correct power reset on a Sony Bravia with HDMI no signal is different from just turning it off with the remote.
Step 1 — Full power reset of TV and HDMI devices
1) Turn the TV off with the remote, then unplug the power cord from the wall for at least 60 seconds.
2) Turn off and unplug your PS5, soundbar, and Chromecast from power.
3) Unplug all HDMI cables from the TV.
4) After 60 seconds, plug the TV back in and power it on first — wait until you see the home screen.
5) Now connect just one device (for example, the PS5) to HDMI 1 with a known-good cable.
6) Turn on the PS5 and use the TV remote’s Input button to manually select HDMI 1.

This sequence forces a new HDMI handshake. If your Sony Bravia still doesn’t detect the PS5 on a simple direct connection, we’ll look at input settings and Bravia Sync next.
Customer
I tried that. With only the PS5 on HDMI 1, it still says “No signal” and the TV doesn’t show the PS5 name in the inputs. I noticed HDMI 3 (ARC) shows my soundbar name, but HDMI 1 and 2 just say “HDMI 1 / HDMI 2” with no device. The Bravia Sync device list is empty.
Technician avatar Technician
Good detail — that means the TV ports are visible, but the devices are not being discovered or identified properly.
Step 2 — Check External Inputs & Bravia Sync (HDMI-CEC)
1) On the TV remote, press Home → go to Settings → Watching TV → External Inputs (wording can vary slightly).
2) Make sure Show all inputs or similar is enabled so inputs aren’t hidden.
3) Check that HDMI signal format for HDMI 1 is set to “Standard format” (at least for testing). If it’s on “Enhanced” and the cable/device can’t handle it, the Bravia may show a black screen or no signal.
4) Go to Bravia Sync settings / Control for HDMI and make sure Control for HDMI is On.
5) In Bravia Sync device list, choose “Search for devices” or “Refresh”.

If your Sony TV still doesn’t discover HDMI devices, we’ll try a different HDMI port and cable, then rule out issues like a soundbar HDMI passthrough blocking the handshake.
Customer
I set HDMI 1 to Standard format and turned Control for HDMI on. Refreshing the Bravia Sync list still says “No devices found”. I tried another HDMI cable and HDMI 2 with the PS5 and Chromecast, but the TV still won’t discover any HDMI devices. Could it be something with the soundbar on HDMI 3 (ARC)?
Technician avatar Technician
Yes, a soundbar on ARC can sometimes interfere, especially if it’s also doing HDMI switching.
Step 3 — Test with a direct HDMI connection only
• Turn the TV off, then unplug the soundbar HDMI cable from HDMI 3 (ARC) so nothing is connected except the PS5 on HDMI 1.
• Turn the TV back on, then power on the PS5. Use the Input button to select HDMI 1 again.
• If you now get a picture, the soundbar’s HDMI pass-through or CEC is causing the “Sony Bravia not discovering devices” issue — we’d re-add it later with simplified settings.

Step 4 — Try a different device and cable
• Connect a simpler device (like the Chromecast or a Blu-ray player) directly to another port, e.g. HDMI 2.
• Use a short, known-good High Speed HDMI cable rated for 4K.
• If none of the devices show up on any port, even after these tests, we’ll also check if your Bravia is not discovering USB or network devices — that helps us see if it’s a broader input issue or only HDMI.
Customer
I disconnected the soundbar completely and tested the Chromecast and PS5 on HDMI 1 and 2 with a short cable. Still no signal and the TV doesn’t identify the devices. On top of that, my Bravia won’t find my Bluetooth headphones now — the Bluetooth device list just spins.
Technician avatar Technician
Since your Sony Bravia is not discovering Bluetooth devices either, this points more to a software or system glitch than only a bad HDMI port.
Step 5 — Check for software update & restart discovery
• Go to Settings → Device Preferences / System → About → System update and check for a Bravia / Android TV software update. Install if available, then reboot the TV.
• After the reboot, put your Bluetooth headphones into pairing mode and go to Settings → Remotes & Accessories → Add accessory. Wait up to 30–60 seconds — if the list stays empty, back out and try again once.

Step 6 — Reset network & Bluetooth modules (soft reset)
• In Settings, temporarily turn Bluetooth Off, then On again.
• If your TV connects to the internet via Wi-Fi, toggle Wi-Fi off/on as well. A corrupted wireless stack can affect both Wi-Fi and Bluetooth device discovery.
If your Bravia still doesn’t discover HDMI, Bluetooth, or casting devices after a software refresh, a deeper TV reset is usually the next step.
Customer
I updated the software and restarted. The TV still won’t discover Bluetooth headphones, and HDMI inputs are the same. I’d rather not wipe all my apps, but if that’s the only way to get the Sony Bravia to detect devices again, I’ll do it. Is there anything else before a full factory reset?
Technician avatar Technician
Totally fair — we’ll try the lighter resets first, then, if needed, a full factory reset.
Step 7 — Reset only picture and external input settings
• Go to Settings → Watching TV → External Inputs and look for Reset / Restore default settings (wording varies). This clears odd HDMI formats and input labeling that can make a Sony TV stop recognizing devices.
• Also go to Settings → Display & Sound → Picture and choose Reset — in some firmware versions this also refreshes HDMI signal handling.

Step 8 — If needed, perform a full factory reset
• In Settings → Device Preferences / System → Reset, choose Factory data reset (erase everything).
• This will sign you out of apps, but it often fixes stubborn cases where Sony Bravia is not discovering any devices across HDMI, Bluetooth and casting.
After reset, we’ll reconnect a single HDMI device and a Bluetooth accessory to confirm discovery is working before reinstalling all apps.
Customer
I did the factory reset. After the initial setup, I plugged the PS5 into HDMI 1 with no soundbar. This time the Sony Bravia detected the PS5 automatically, showed the name in the input list, and the picture works. Bluetooth headphones also pair now. Can I safely add the soundbar and Chromecast back?
Technician avatar Technician
Great — that confirms it was a software/handshake issue and not dead HDMI ports.
Step 9 — Re-add other devices without breaking discovery
• Add the soundbar back to HDMI 3 (ARC/eARC) and enable ARC/eARC under Audio output if needed.
• Keep consoles/streaming sticks connected directly to TV HDMI where possible; use the soundbar only for audio return instead of HDMI switching.
• Turn Bravia Sync (Control for HDMI) on for devices that support HDMI-CEC, but if a specific device causes the TV to stop discovering others, leave CEC off for that device only.

Preventive tips so your Sony Bravia keeps discovering devices
• Power on devices in this order: TV → soundbar/receiver → console/box. This avoids HDMI handshake glitches.
• Use short, certified HDMI cables; replace any that feel loose or are visibly damaged.
• Avoid rapidly switching inputs while devices are booting.
• When a Sony Bravia stops detecting HDMI devices again, start with the full power reset (TV and devices) before changing lots of settings.
If you ever get stuck at any step, an Expert can walk through your exact Sony menu labels in real-time.
Customer
After the reset and reconnecting everything in the right order, the Sony Bravia discovers HDMI devices correctly, Bravia Sync lists the PS5 and soundbar, and my Bluetooth headphones pair. No more “No signal” or missing devices. Thanks a lot!

Summary: when a Sony Bravia is not discovering devices (HDMI, Bluetooth, casting), first do a proper power reset of the TV and devices, then check External Inputs, HDMI signal format, and Bravia Sync / Control for HDMI settings. Test with one device and one HDMI cable directly to the TV, then add soundbars and other gear. If discovery is broken across HDMI and wireless, a software update and, if needed, a factory reset usually fix it. Not sure which Sony menu to use?

Quick answer: the accepted fix

Accepted fix when a Sony Bravia is not discovering devices: fully power-cycle the TV and all HDMI devices, then connect one device directly to a single HDMI port with a known-good cable. Set that HDMI port to Standard format, enable Control for HDMI / Bravia Sync, and manually select the input. Once the TV detects and names that device correctly, add other HDMI, Bluetooth and casting devices one by one, avoiding HDMI pass-through issues from receivers or soundbars. If discovery fails across all inputs, update the TV software and perform a factory reset.

Why Sony Bravia TVs stop discovering devices

Most cases of a Sony Bravia not discovering devices come down to three things: HDMI handshake problems, disabled or mis-configured input settings, or software glitches. A flaky HDMI cable, a soundbar that passes video incorrectly, or a mismatch between the TV’s HDMI signal format and the console’s output can make the TV show “no signal” and never identify the source. If Bravia Sync / Control for HDMI is off, the TV may not populate the Bravia Sync device list even when devices are connected. Firmware bugs can also affect Bluetooth and Wi-Fi device discovery, so wireless headphones, speakers, and casting devices don’t appear until the TV is updated or reset.

How to test if Sony Bravia device discovery is really fixed

After troubleshooting, leave your external devices connected and run a few quick tests. Turn the TV off and on and see if your PS5, streaming box, or soundbar appears with the correct name under Inputs and Bravia Sync device list. Switch between HDMI ports to confirm you no longer get “No signal” or a black screen. Pair a Bluetooth speaker or headphones and verify they reconnect automatically after the TV restarts. Try screen mirroring from a phone or tablet to check if the Bravia now shows up as a casting target. If everything reconnects reliably, your Sony Bravia device detection is likely fixed; if a single port or device still fails, the issue may be local to that cable, port, or accessory.

Sony Bravia not discovering devices — quick troubleshooting tips

Most cases are fixed by resetting HDMI handshake, checking input settings, and updating software.

Quick path: unplug the TV and all HDMI devices for at least a minute, then reconnect one device directly to a single HDMI port with a good cable. Set that port to Standard format, enable Control for HDMI / Bravia Sync, and refresh the device list. Test Bluetooth and Wi-Fi device discovery after a software update and soft reset of wireless modules. Avoid daisy-chaining everything through a soundbar or receiver until you know the TV detects each device on its own. If a specific accessory makes your Sony Bravia not detect other devices, leave CEC off for that accessory or replace the HDMI cable or switch.

FAQ

Why is my Sony Bravia not discovering HDMI devices?

A Sony Bravia not discovering HDMI devices is usually caused by a bad HDMI handshake, wrong HDMI signal format, a faulty or incompatible cable, or disabled inputs. Try a full power reset of the TV and devices, connect one device directly with a short High Speed HDMI cable, set the port to Standard format, and make sure the input is not hidden in External Inputs. If multiple devices fail on multiple ports, update the TV software and consider a factory reset.

How do I turn on Bravia Sync so the TV discovers devices?

On most models, press Home → Settings → Watching TV → External Inputs → Bravia Sync settings and turn Control for HDMI (Bravia Sync) on. Then open the Bravia Sync device list and choose “Search for devices”. Devices that support HDMI-CEC (like PS5, Blu-ray players, or receivers) should appear and can then be controlled with the TV remote.

Sony Bravia can’t find my Bluetooth speaker or headphones — what can I do?

Make sure Bluetooth is enabled on the TV under Settings → Remotes & Accessories and put your speaker/headphones into pairing mode near the TV. If the list stays empty, toggle Bluetooth off/on, power-cycle the TV, and check for a software update. Resetting network and Bluetooth settings or, in stubborn cases, doing a factory data reset usually restores Bluetooth device discovery.

When should I factory-reset my Sony Bravia for discovery issues?

If your Sony Bravia still won’t discover HDMI, Bluetooth, USB, or casting devices after you’ve tried power resets, different cables and ports, refreshed Bravia Sync, and updated software, a factory data reset is the next step. It erases apps and settings but often fixes deep software glitches that affect all types of device detection.
