AV receiver won't switch between HDMI inputs

This is usually a remote/button issue, an HDMI-CEC conflict, or a receiver needing a reset rather than failed hardware. Checking the input button and trying a reset fixes most cases.

Difficulty
Moderate
Time
15–30 minutes

Symptoms

  • Pressing the input button doesn't change the displayed source
  • Receiver switches inputs but picture/sound doesn't follow
  • Only some inputs are selectable
  • Input switching is delayed by several seconds

Likely causes

  • CommonRemote or front panel button not registering the input pressA worn button or weak remote signal can prevent the switch from happening.
  • CommonHDMI-CEC from a connected device forcing input back automaticallyA device like a game console or TV can send CEC commands that override manual input selection.
  • PossibleReceiver software needs a restart/resetA minor software hang can prevent input switching from working correctly.
  • PossibleHDMI handshake issue with a specific connected deviceSome devices have compatibility quirks that prevent clean switching.
  • Less commonFailing internal HDMI switching chipA hardware fault in the HDMI matrix switching component can cause selective or total input failure.

What to do

  1. Try switching inputs using both the remote and the front panel buttons to rule out a remote-specific issue.
  2. Turn off HDMI-CEC on connected devices (game consoles, streaming boxes) temporarily to prevent them from overriding input selection.
  3. Power cycle the receiver completely by unplugging it for a minute.
  4. Test each HDMI input individually with a different, known-good device to identify if only certain inputs are affected.
  5. Check for and install any firmware updates for the receiver.
  6. If specific inputs never work regardless of device, this points to a hardware fault in that HDMI port or the receiver's switching chip.

When to call a pro

If specific HDMI inputs consistently fail across multiple devices after a reset and firmware update, the receiver's HDMI board likely needs professional repair.
