Before the test
List the exact model, player build, login format, start time and expected outcome for IPTV EPG and TV guide. An EPG is schedule data supplied by the service or imported separately, then interpreted by the player.
During the test
Check the current time zone and whether the player successfully refreshed its guide. Note one successful case and one problematic case, including time, channel/category and which connection was used.
After the test
Record the support answer, current price, currency, connection count and any app fee. Assuming an empty guide means the video stream is down. Save only necessary details and never expose a password in a public checklist.
What to do next
Open the relevant brand page and check the original supplier information before ordering. For a technical issue, write down the device, player, connection and one reproducible example. For a price question, ask for the full charge in the currency you will pay.
