Possible Causes

Faulty touchpad or button PCB, Loose ribbon cable between keypad and main PCB, Liquid spill into control panel, Main PCB input failure

How to Fix / Troubleshooting

Safety first: Disconnect power before opening the front cover and accessing electronics.

  • Step 1 – Try remote control:
    • If the remote still controls the unit, the issue is likely with the keypad only.
  • Step 2 – Inspect keypad connections:
    • Remove the front cover and locate the small keypad PCB.
    • Ensure the ribbon cable or connector to the main PCB is firmly seated.
  • Step 3 – Check for moisture damage:
    • Look for signs of water ingress or corrosion on the keypad board.
  • Step 4 – Replace keypad PCB:
    • If buttons remain unresponsive, replace the keypad/control panel PCB with a Hisense-compatible part.
  • Step 5 – PCB replacement: If neither keypad nor remote works, the main PCB may need replacement by a technician.
