Troubleshoot a signage image rotation that stops

What the symptoms point to

Use these observations to choose your next check. They are clues, not proof of a particular fault.

• The first image remains visible, but settings still open: check the loaded image set and expected display interval before treating this as an app failure.
• The same image appears after each expected transition: check for duplicate exports or slides whose differences are too small to notice from your viewing position.
• The rotation always stops before the same image: inspect that image and its export format. A repeatable boundary helps narrow the file check.
• A replacement card produces the old artwork: check whether the replacement content was actually loaded. Inserting different media is not evidence that the active playlist changed.
• The app disappears or the Android home screen appears: investigate app startup or an app stop separately from a picture that simply remains visible.
• Images advance, but not at the expected pace: check the configured interval and transition effect. A slow rotation is a different problem from a sequence that never advances.

For the distinction between a playback app and other player categories, use the digital signage player guide. This diagnosis concerns an image playlist, not a browser page or a custom application.

Build a small reference image set

Keep your original artwork and current media unchanged. Prepare a separate diagnostic set containing three images with large labels: A, B and C. Give each a different background and a clearly different layout. You should be able to identify each image without reading small text.

Export all three as JPG or PNG. The included signage player also supports WebP images, but using one format throughout the first check removes an unnecessary variable. PowerPoint, PDF, HEIC and GIF files do not play. Changing a filename extension does not convert the file; export it from the application that created it.

Open each exported file on the computer used to prepare the media. Check that it contains the intended artwork rather than a blank page, an old revision or another copy of A. This establishes that the exports are readable there, not that playback on the sign has been established.

Use simple filenames so your notes are unambiguous. Do not assume alphabetical filenames control playback order unless the installed player's loading instructions say so. Record the intended order separately.

Keep the image dimensions and orientation consistent across the set. If rotation or cropping makes the labels hard to identify, follow the portrait signage image preparation steps. Layout is worth correcting, but it should not be confused with a failure to advance.

Check one variable at a time

Run the short reference set before returning to the full presentation.

1. Record the starting conditions. Note the player in use, media source, intended image order and expected interval. Also note whether you are using local files or optional remote sync.
2. Load only the reference set. Use the installed player's content-loading workflow. Keep unrelated images and videos out of this diagnostic playlist.
3. Confirm the new content is active. Look for the distinctive A, B or C artwork. If you still see the old presentation, resolve the loading step before changing timing.
4. Use a clear transition. The included player offers a hard cut as an alternative to its default crossfade. A hard cut makes a change between reference images easier to spot.
5. Observe longer than one expected interval. Note the first visible change, the next image and whether the sequence returns to its beginning. Use a clock rather than estimating elapsed time.
6. Change one item and repeat. If a particular image is suspect, re-export or replace that image while leaving the rest of the set unchanged.

If an image cannot be opened on the preparation computer, re-export it from the original artwork. Do not rely on a player to repair an incomplete or damaged file. If copying to removable media reports an error, resolve that error and make a fresh copy before drawing conclusions about playback.

The included player keeps a copy of the show in internal memory. It is designed to continue playing that copy when the card is removed. Card removal therefore does not establish whether your latest files were loaded, and it is not a useful first check for sequence progression.

Separate timing from player state

Write down what you expect before watching the screen. “It stayed on A for a long time” is less useful than “A was still visible after two expected display intervals.”

If your target is ten images at 30 seconds each, the nominal cycle is five minutes, calculated as ten multiplied by 30 seconds. Transition handling can affect the observed cycle, so record both the interval between changes and the time taken to return to the first image. Do not declare the entire sequence complete after seeing only the first transition.

Use the timing controls documented for the player actually installed. This page does not establish a particular interval setting or timing precision for the included software. If you cannot identify the relevant setting, record the observed interval and request clarification through the player section before assuming the sequence has stopped.

A visible picture also does not prove that the playback app is still active. If the app stops, the included player is designed to start again within seconds and return to playing. That recovery behavior is separate from diagnosing which image should appear next. Do not use repeated app restarts as a substitute for checking the active files and timing.

If the issue is that playback never opens correctly, follow the single-purpose display startup guidance instead. Keep app launch and image progression as separate checks.

Apply the fix that matches the result

If the three-image set advances but the full presentation does not, add the original images back in small groups. Keep a written list of each group. When the symptom returns, you have a smaller set to inspect rather than an entire presentation to rebuild.

If one export consistently marks the problem boundary, recreate it from the source artwork in the same format as a working image. Check its contents and reload the revised set. A successful first image does not establish that every remaining file is usable.

If the sign continues showing old artwork, correct the content-loading workflow rather than adjusting transition effects. For an installation using remote updates, distinguish the local reference set from the remotely supplied playlist. The remote signage content workflow explains that broader content path.

If the reference set also fails to advance, preserve your observations before making more changes. Record whether the app remains accessible, which image is visible and how long you waited. Avoid changing the media, interval, transition and startup configuration together. That removes the comparison needed to identify what helped.

Check the complete rotation again

After the repair, observe every intended image and the return to the beginning. Then repeat the same check using the same files and settings. A repeatable result matters more than a single successful transition.

For a useful playback record, keep:

• The intended sequence and the image actually shown at each change.
• The expected interval and the observed interval between changes.
• The file formats and media source.
• Whether the issue occurs with the three-image reference set, the full presentation or both.
• The last single change made before the result improved or worsened.

If a power interruption is part of the symptom, handle that as a separate check using the offline display power-loss recovery guidance. It should not replace watching a complete rotation during normal playback.

Keep the final exports and a short loading note together. The downloads section provides the content guide and starter slide packs for preparing future revisions. Retaining a known reference set gives you a quick way to separate the next artwork change from a playback problem.
