The Complete TV Guide Troubleshooting Handbook

A disciplined guide investigation separates schedule data, channel identity, time context, filters, device presentation, remote focus, layout, and performance before any reset.

In short: Name one visible guide symptom, preserve its first timestamp, and freeze the account, profile, authorized source, channel group, filters, guide window, device clock, time zone, device, and application version. Compare a few channel and program samples with the source schedule, then separate data, channel identity, time conversion, layout, remote focus, and performance. Change one reversible variable and send support redacted observations, not implementation guesses.

A guide combines channel identity, schedule metadata, time context, and a navigable grid. Similar screens can therefore fail for different reasons. The safest method begins with what the user can see and avoids assumptions about import, matching, refresh, or storage.

Define the smallest symptom

Choose one result: the grid is empty, now-and-next information appears old, listings are shifted, one channel has no schedule, programs overlap, a program is mapped to the wrong channel, search returns nothing, a filter hides channels, focus becomes stuck, or scrolling feels slow. Do not combine them into “the guide is broken.”

Freeze the guide context

Record the Norva account, active profile, privacy-safe source label, channel group, filters, search query, selected date and time window, device clock, device time zone, network, device model, operating system, application version, and timestamp. Keep those values stable during comparison.

Separate six evidence layers

Treat these as independent until evidence connects them:

The authorized source's current channel and schedule data.
The identity of the channel and program being compared.
Device clock, time zone, daylight-saving context, and guide window.
Filters, groups, search, and profile context.
Grid layout, remote focus, and visible navigation state.
Device load, application version, network, and observation timeline.

The interface does not reveal Norva's internal guide-processing rules.

Build a minimal channel sample

Choose up to three channels: one affected channel, one normal control, and one adjacent channel when mapping or overlap matters. Use masked labels. Record visible channel name, logo state, source identity cue, current listing, next listing, start and end times, and description only as needed.

For a completely blank grid, use the empty-guide context check. For partial coverage, use the one-channel comparison.

Verify source schedule evidence

Through the provider's official authorized route, record whether each sampled channel and listing currently exists, with the source's own labels and timestamps. Source data is one observation; it does not prove how Norva maps or displays the entry.

Verify time before content

Capture device-local time, automatic or manual clock state where visible, time zone name, offset, selected guide date, and travel or daylight-saving changes. A one-hour shift belongs in the time-context checklist, not in a title or channel correction.

IANA maintains the time-zone database, but its existence does not establish which version a particular device or application uses.

Verify channel and program identity

Same-name channels can have different source identifiers, regions, schedules, or versions. Compare source label, channel number or identifier where visible, logo, program title, start time, and description. Use the channel-program mapping guide when the program belongs to another visible channel.

Separate data from layout

If text is clipped, rows overlap, or grid cells cover one another, confirm whether the underlying listings remain discoverable through focus or detail views. The overlapping-listings check treats layout separately from schedule membership.

Separate focus from performance

Record which element has visible focus, the remote direction pressed, the expected neighboring element, and the actual result. A focus trap is not the same as slow scrolling. Use the remote-focus diagnostic or guide scrolling comparison as appropriate.

Change one reversible variable

Remove one visible filter, compare one supported device, or check one trusted network while keeping everything else stable. Restore baseline before another test. Avoid clearing application data, reinstalling, removing the source, editing schedules, or issuing repeated refreshes before evidence exists.

Escalate a compact record

Send support one symptom, timestamps, stable context, device and version, masked source and channel samples, source observation, time context, focus path or layout evidence, one controlled comparison, and every action taken. The guide support evidence template protects private source data.

Original evidence: guide diagnostic matrix

Layer	Affected sample	Control sample	Observation
Source schedule
Channel and program identity
Clock, zone, guide window
Filters and profile
Focus and layout
Device, version, network
Timeline and actions

Common mistakes and limitations

Comparing different guide windows, profiles, or filters.
Matching channels by name or logo alone.
Editing schedules before checking device time context.
Treating layout, focus, and performance as one symptom.
Repeating refreshes without preserving the first timeline.
Sharing complete private source or channel lists.

Frequently asked questions

Which layer should I check first?

Start with the smallest symptom, stable context, source sample, and device time. Those observations determine the relevant branch.

Should I refresh repeatedly?

No. Preserve the first sequence and use current Norva support guidance. Repetition can obscure which action produced a later screen.

How many channels should I document?

Use a minimal representative sample: one affected channel, one control, and one adjacent or related channel when mapping matters.
