The Echo Show 15 (2nd Gen) screen goes dark, touch stops responding, or Alexa ignores the wake word. This usually clears up in under two minutes once you know where to start.
First, pull the power cable from the back of the display. Hold off for a full 30 seconds, that gives the internal electronics time to fully discharge. Plug it back in. The screen lights up, boots for about 45 seconds, then settles. Test by saying "Alexa" or tapping the screen. That soft restart fixes the large majority of frozen or unresponsive Show 15s.
If the screen stays dark or the device is still unresponsive, here's what's likely going on and how to walk through it.
What Usually Causes an Echo Show 15 to Freeze
The 2nd-gen Echo Show 15 (released in 2024) runs a Fire TV based operating system under the hood, which creates a few unique failure points:
- Wi-Fi 6E band confusion: the device supports 2.4, 5, and 6 GHz. If your router broadcasts separate SSIDs, the Show may hop onto a band that briefly drops or weakens.
- Fire TV mode lag: after extended use, the Fire TV interface can accumulate background processes that make the whole UI sluggish or unresponsive.
- Widget desync after a firmware update: Family Hub widgets sometimes lose synced data, which can stall the home screen.
- Misbehaving Skill or routine: a third-party Skill in a failure loop can hang the device while it waits for a response.
- Alexa+ rollout partial state: if you've enabled the optional Alexa+ (free with Prime, $19.99/month standalone), a partial migration can break wake-word handling.
- Camera auto-framing processing: the 13MP wide-angle camera with auto-framing occasionally consumes enough CPU to make other inputs slow when multiple people are in the room.
Check the Microphone Status (On-Screen or Alexa App)
The Echo Show 15 doesn't have a physical mute button on the frame. Instead, the mic toggle lives in the Quick Settings panel, swipe down from the top of the screen and look for the microphone icon. If it's crossed out, tap it to unmute. You can also check in the Alexa app: tap Devices, select your Show 15, then scroll down to Microphone status. A thin red indicator might be visible in the top-left corner of the screen when mics are off, but it's easy to miss on a bright background.
Force a Clean Reboot (Not Just Sleep)
Many people hit the power button on the remote or use the sleep timer, but that doesn't fully reset the OS. You need a true power cycle. Unplug the AC adapter from the back of the Show (not the wall outlet). Count a full 30 seconds, capacitors need that time to drain, then reconnect. The screen goes through a full boot sequence with the Amazon logo. This is the single most reliable fix for a frozen screen or unresponsive touch.
Check the Alexa App for Device Status
Open the Alexa app on your phone, tap Devices, then select your Echo Show 15. If it shows "Offline," the device lost Wi-Fi. If it shows "Online" but the screen is dark or unresponsive, the OS is hung but the network is alive. Either way, a soft restart (the power-cycle step above) almost always clears it.
Reconnect to Wi-Fi Through the Alexa App
If the app shows "Offline," walk through wireless setup. In the Alexa app, tap the Show 15, then Settings > Wireless > Change. During setup, choose the 5 GHz band if you can, it's the sweet spot for reliability on Wi-Fi 6E devices. Once connected, the router handles band steering to 6 GHz if it supports it. If your router splits bands into different SSIDs, stick with the 5 GHz one for now.
Force a Firmware Update Check
Amazon pushes Echo firmware updates silently when the device is idle. To prompt a check, leave the Show 15 plugged in and unused for at least 30 minutes. It'll ping the update server and download any pending firmware. Then unplug, wait 30 seconds, and plug back in, the update installs during the boot cycle. If the device becomes unresponsive again right after boot, you may have hit a firmware bug that a factory reset (below) will fix.
Disable a Recently Enabled Skill
If the Show 15 responds to some voice commands but ignores others, a Skill is probably hanging. In the Alexa app, go to More > Skills & Games > Your Skills. Sort by "Recently Used" and look for any Skill that was enabled or updated around the time the problem started. Disable one, then test the wake word. If responsiveness returns, that Skill was the trigger.
Restart Fire TV Mode Separately
Built-in Fire TV mode has its own memory and process management. If the Fire TV interface is laggy or not responding, you don't need to reboot the whole Show. Press and hold the Home button on the included Fire TV Alexa Voice Remote for about 5 seconds. A menu appears, select Restart. This reinitializes the Fire TV subsystem without affecting Alexa widgets or the home screen layer. I've seen this fix menu lag that a full power cycle didn't.
Resync Family Hub Widgets
After a firmware update, widgets like Calendar or Shopping List sometimes stop updating. Open the Alexa app, tap Devices, select the Show 15, then Settings > Widgets. Uncheck a widget, then re-enable it. The Show 15 fetches fresh data within a minute. If multiple widgets are stale, do one at a time, that keeps the OS from glitching.
Factory Reset the Echo Show 15 (2024)
If none of the above work, a full factory reset is the last software step. On the Show 15 screen, go to Settings > Device Options > Reset to Factory Defaults. Confirm the reset. The device wipes all Skills, routines, Alexa+ preferences, and paired Bluetooth devices. Setup takes about 10 minutes through the Alexa app after the reboot.
Reboot Your Wi-Fi Router
If other smart devices in the house are also showing connectivity issues, the router is the common point of failure. Unplug your router's power for 60 seconds, plug it back in, and wait 3 minutes for the network to fully stabilize. The Show 15 reconnects automatically. This step is especially worth trying if the Show 15 shows "Online" in the app but still won't respond, sometimes the device has an IP lease that's stuck in a dead end.
If the screen remains dark even after a factory reset and the power cycle does nothing, the display or mainboard may have a hardware fault. That's outside what software fixes can address, so reach out to Amazon support, the 2nd-gen Show 15 is still under its standard 1-year warranty for manufacturing defects.
