Meeting Room Troubleshooting: The Complete Guide
Most meeting room faults are fixable in minutes without an engineer. Run the five universal checks below first - power, cables, restart, platform status, fresh call - then jump to the step-by-step guide for your exact symptom: camera, audio, screen, connection or touch panel. If you would rather hand it straight to a human, we support every major vendor, whoever installed the room.
The five universal checks (do these first)
Whatever the symptom, these five checks resolve the majority of "broken room" reports before any deeper diagnosis.
1. Wake everything up
Tap the touch panel, check the display is on the right input and not in standby, and look for power lights on the camera and bar. Sleeping kit explains more 'broken rooms' than any real fault.
2. Reseat the obvious cables
Push home both ends of the HDMI and USB cables, and any network cable to the bar or codec. A cable that looks connected can be a millimetre out - especially after a room has been cleaned.
3. Restart the room system
Restart the room from the touch panel's settings menu, or power-cycle the room PC or bar and give it two minutes to come back. This clears the majority of software-state faults.
4. Check it isn't the platform
If every room is misbehaving at once, check the Microsoft 365 or Zoom service status pages before touching hardware - an outage upstream looks identical to a broken room.
5. Test with a fresh meeting
Start a new test call rather than rejoining the broken one. If the test call works, the problem was the meeting, not the room.
Still broken? Go by symptom
Each guide works through every cause in order of how often we actually see it, with numbered fixes and an honest line on when to stop and call us.
Camera not working
Most common causes
- ·The camera is asleep, powered off, or the lens cover is closed
- ·A cable has come loose, is damaged, or is in the wrong port
- ·The wrong camera is selected in Teams or Zoom
No audio or echo
Most common causes
- ·The mic or speaker is muted, or the device is asleep
- ·A cable, power supply or USB connection has come loose
- ·The app has the wrong microphone or speaker selected
Screen not displaying
Most common causes
- ·The screen is off, asleep, or on the wrong input
- ·A video cable is loose, damaged, or unplugged
- ·Laptop content isn't appearing even though the room screen works
Can't connect or join
Most common causes
- ·The touch panel or compute unit is asleep, off, or unplugged
- ·The network cable is unplugged or the connection has dropped
- ·The room's sign-in has expired or been signed out
Touch panel not responding
Most common causes
- ·The panel is asleep or in power-saving standby
- ·A power or data cable has come loose
- ·The panel software has frozen
Screen sharing not working
Most common causes
- ·The cable, adapter or dongle chain has a weak link
- ·Your laptop isn't actually sending a picture out
- ·The room hasn't switched away from its home screen
Audio crackling or dropping out
Most common causes
- ·A cable has worked loose, at either end
- ·The one affected mic or speaker just needs a restart
- ·Something changed on the network recently
Room won't sign in
Most common causes
- ·The room PC or console is just stuck - a restart clears it
- ·The room got signed out - by a person, an update, or a reset
- ·The room account's password has expired overnight
Booking panel wrong or offline
Most common causes
- ·The booking hasn't shown up on the panel yet (a normal sync delay)
- ·The room was never actually booked, only typed as a location
- ·The last meeting is still 'open', or an ad-hoc reservation was never released
Calls dropping or freezing
Most common causes
- ·The room system is connecting over Wi-Fi instead of a wired cable
- ·Everyone's on a call at the same time and the network can't cope
- ·Wi-Fi interference or the room device losing (roaming) its connection
TV won't turn on with the system
Most common causes
- ·CEC is switched off on the TV itself
- ·The room system's own CEC / display-control setting is off
- ·The TV is plugged into the wrong HDMI port
Divisible room not working
Most common causes
- ·The room hasn't noticed the wall has moved - it's still on the wrong setting
- ·You can hear the room next door, or your call can hear them
- ·Echo or doubled-up sound, but only when the room is combined
Ceiling mic not picking up voices
Most common causes
- ·Something is physically blocking or muting the microphone
- ·The room has moved on but the microphone's settings haven't
- ·Some seats sit in a genuine dead spot
Echo with multiple microphones
Most common causes
- ·Someone's own laptop is quietly live in the call
- ·Something changed in the room since it last worked properly
- ·The echo canceller is listening to the wrong thing
None of these fit?
