Possible Causes

Failed LED display module, Loose connector between display and main PCB, Damaged LED driver circuit, Overvoltage event affecting display components

How to Fix / Troubleshooting

Safety first: Remove the battery before inspecting the display area.

  • 1. Power cycle: Remove the battery for 1 minute, then reinstall and power on to see if the display recovers.
  • 2. Check for cracks: Inspect the display window for cracks or impact damage that may have damaged the module.
  • 3. Observe behavior: Note if the vacuum still runs normally despite the display fault. If suction and controls work, the issue is likely limited to the display module.

Repair: Display module or LED board replacement requires disassembly of the handle or main body and reconnection to the main PCB. This should be performed by an authorized TCL service center.
