Three symptoms, three different faults, and treating them alike is why generic advice fails. A completely blank guide means the guide file never arrived or never parsed, so the app has nothing to render. Correct program titles sitting at the wrong hours mean the file arrived and parsed correctly, and the offset applied to it is wrong. A guide that populates some channels while leaving others empty means the file arrived, parsed, and simply has no entry that matches those channel identifiers. Notice that in two of the three cases the download worked. That is why reinstalling the app, the standard first suggestion, fixes almost nothing here.

1. 1Blank everywhere: the file never downloaded or never parsed
2. 2Right shows, wrong times: offset or time zone
3. 3Some channels only: identifier matching

Playback and guide data travel separately. The playlist tells the player where to fetch video, while the guide is an XML file listing programs against channel identifiers. The app joins the two by matching each channel's identifier to an entry in that file. If a service renames a channel, changes its identifier, or adds channels the guide file does not cover, the join silently fails for those entries and you get empty rows beside a picture that plays flawlessly. That is a data mismatch, not a fault in your device, your connection or your subscription. The repair is on the service side or in a manual per-channel mapping, not in a router reboot.

1. 1Video and guide are two separate fetches
2. 2Empty rows next to working video means an identifier mismatch
3. 3Renamed or newly added channels are the usual trigger

Most players pull the guide once a day and then serve it from cache, so a fault you already fixed can persist until the next cycle. Clear the app cache, then sign out and back in to trigger a fresh pull rather than waiting a day. On devices with little free storage the write can fail partway through, leaving a truncated file that renders as a partial guide every time, so free up space before you try again. Also confirm the device clock is set to network time and the correct region, because the app positions programs against local time and a wrong clock shifts everything by exactly the size of the error.

1. 1Clear cache, then re-add the login to force a fresh pull
2. 2Free storage before reloading on low-space devices
3. 3Set the device to network time and the right region

A working guide is not decoration. It drives catch-up, recording timers and the now-and-next view, so an empty guide quietly removes features you paid for. That makes guide coverage worth checking during a trial rather than after a year. Open the groups you actually watch, scroll a full day forward, and see whether the rows fill in. IP4KTV carries guide data alongside 54,000+ live channels and 219,577+ VOD titles across 190+ countries, and a $5 24-hour trial is long enough to watch one refresh cycle complete. Judge the guide the same way you judge a stream: by looking at it, not by reading a claim about it.

1. 1The guide drives catch-up and recording timers
2. 2Scroll a full day ahead during a trial to test coverage
3. 3Check the groups you watch, not the total channel count
