Battery will not charge; charger LED stays off or blinks abnormally.

Safety first: Unplug the charger before inspecting it. Do not use damaged power adapters.

• 1. Inspect charger: Check for physical damage to the charger and cable. Replace if any damage is found.
• 2. Try another outlet: Use a different wall socket to rule out power issues.
• 3. Clean contacts: Wipe the charging contacts on the dock and vacuum with a dry cloth.
• 4. Reseat battery: Remove and reinstall the battery pack to ensure good contact.
• 5. Observe LED codes: Refer to your TCL manual for charger LED meanings (steady, blinking, color) to identify charger vs. battery fault.

If still not charging: Replace the charger first. If the issue persists, the battery pack or internal charging circuit is faulty and should be serviced.
