Troubleshooting: Advertising on CFDs

Having issues with Rear Screen or DAS? Find solutions to common problems below.

Rear Screen Issues#

Problem: Ad is not appearing on the Rear Screen#

All five scheduling conditions must be true simultaneously. Check each one:

Problem: Ad changes are not showing on screen#

Cause: The Rear Screen refresh cycle (~30 seconds) has not completed yet.

Fix: Wait 30 seconds, or log into the till to force an immediate refresh.

Problem: Rear Screen is still showing an expired campaign#

Cause: The ad was not deactivated after the campaign ended, or the End Date was not set.

Fix: Deactivate the ad from the dashboard. For future campaigns, always set an End Date so the ad stops automatically.

Problem: Cannot upload an ad image#

Cause: The image is not in JPG format.

Fix: Convert the image to JPG before uploading. PNG, GIF, BMP, and other formats are not accepted.

Problem: Ad appears at wrong times#

Cause: Daily Start Time or End Time is misconfigured.

Fix: Edit the ad and verify the Daily Start Time and End Time settings.

Problem: Ad shows on the wrong days#

Cause: Days of Week selection is incorrect.

Fix: Edit the ad and verify which days are selected.

Problem: Ad shows at the wrong locations#

Cause: Location assignment is missing or incorrect.

Fix: Edit the ad and verify the Specific Locations setting.

Problem: Ad rotation is off across all locations#

Cause: Ad Rotation may be disabled in Organisational Settings.

Fix: Profile icon > Organisational Settings > Ad Rotation > enable Enable Ad Rotation.

DAS Issues#

Problem: DAS device is not showing any content#

Cause: Device is not paired, the connection was lost, or no schedule is assigned.

Fix:

1. Verify device pairing in Paimnt HQ > Site > Devices
2. If the device shows as disconnected, re-pair it using a new pairing code
3. In the Devices tab, confirm at least one schedule is assigned to the device

Problem: DAS ads are not appearing at the scheduled times#

Cause: Schedule timing is wrong, or the site timezone is incorrectly configured.

Fix:

1. Check the schedule time restrictions in the Schedules tab
2. Verify the site timezone in Till Settings > Settings > Business Details > Timezone

Problem: Wrong ads are displaying during a meal period#

Cause: Schedule conflicts, or schedules are assigned to the wrong device.

Fix:

1. Open the Devices tab and check which schedules are assigned to the device
2. Check that the active schedule’s time window matches the intended meal period
3. Look for overlapping schedules on the same device — if two schedules cover the same time window, both may attempt to display simultaneously

Problem: An ad is displaying for the wrong duration#

Cause: The ad’s Display Duration is incorrectly set.

Fix: Edit the ad in the Ads tab and update the Display Duration field.

Problem: Cannot assign an ad tag when creating an ad#

Cause: No tags have been created yet.

Fix: Create the tag first — Ads tab > filter toggle (top right) > + Add Tag. Return to the ad form and the tag will be available.

Problem: A schedule is not appearing on the device#

Cause: The schedule has not been assigned to the device.

Fix: Open the Devices tab > Edit the device > under Available Schedules, add the schedule and save.

Problem: A newly created ad or schedule is not showing in the list#

Cause: The UI has not refreshed yet.

Fix: Click the refresh button next to the + Create Ad or + Create Schedule button.
