A television’s USB socket may not supply the power required by a streaming stick, particularly during startup or demanding tasks. Use the device manufacturer’s recommended power adapter and cable. Unexpected restarts during app launch can be a power problem rather than a player-account or subscription fault. A startup logo or illuminated status light only shows that some power is present. Check behaviour under the same workload with the recommended supply before treating repeated restarts as evidence of corrupted application settings.
Read the power requirement
USB ports vary in their available current and behaviour when the television enters standby. A port that lights the stick does not prove it provides stable power under load. Read the stick's manufacturer instructions and the ratings on its intended adapter. A TV USB port may be designed for files or accessories rather than powering that device continuously. Also inspect the cable and connectors for a loose fit; a suitable adapter paired with a damaged or unsuitable cable can still leave an unstable power arrangement.
Use a controlled comparison
Try the supplied or manufacturer-approved adapter without changing other settings. If the restarts stop, the result points toward the previous power arrangement, though it is not a complete hardware diagnosis. Use the same player, stream and display input when comparing the two power sources. Changing networks or reinstalling the app at the same time would weaken the comparison. If restarts continue on the recommended power setup, note whether they affect the entire device or only the app, then investigate heat, firmware or hardware through manufacturer support as appropriate.
Distinguish standby from failure
If the TV turns its USB power off, the stick may cold-start each time the TV is turned on. That can explain a long startup without implying the application has erased its settings. Watch for the device's complete startup sequence after the television wakes. If it cold-starts every time USB power is removed, a slower return to viewing is expected. That differs from losing stored playlists or credentials, which should be checked separately. Avoid interrupting an update simply to test standby behaviour; complete the update before making the power comparison.

An example to work through
A stick that works on its wall adapter but restarts from the TV’s USB socket should be investigated as a power-supply issue before reinstalling the player. Keep the stream and network unchanged while comparing power sources. If the restart follows the power arrangement rather than one app action, report that evidence with the device model and adapter details.
Questions about this topic
Does any USB port provide the same power?
No. Port capability and standby behaviour vary.
Will clearing player cache fix insufficient power?
No. Cache settings cannot increase the power supplied to the device.
