Check the data source configuration
Open the EPG settings and confirm that at least one data source is enabled and pointing to a valid URL or broadcast channel. If using an online source, verify the URL in a browser. If using broadcast EPG, confirm that the correct channel is selected as the data carrier.
Verify network access
Online EPG sources require internet connectivity. Test the connection by opening the EPG URL in a browser on the same computer. If the site is blocked by a firewall or proxy, configure the exception in your security software.
Check time-zone settings
If program times appear shifted by a fixed amount, the computer time zone may be incorrect or daylight saving time may not be synchronized. Set the time zone in Windows to match your actual location and enable automatic time synchronization.
Test broadcast EPG signal
Some channels carry EPG data on specific transponders. If only some channels have listings, the data may be coming from a transponder with weak signal. Improve the signal quality before relying on broadcast EPG.
Clear the EPG cache
Delete the local EPG cache files if the application stores them. The cache can contain outdated or corrupt entries that prevent new data from loading correctly. Restart the application after clearing the cache.
Check application logs
Open the application log file and search for EPG-related entries. Error messages there often point directly to the problem, such as a timeout, authentication failure, or unsupported format.
