General A/V Troubleshooting

The following will be a series of common issues and their troubleshooting/resolution steps.


NOTE: When responding to any equipment related issue, have the relevant temporary replacement on a cart and ready to be implemented in the classroom should the troubleshooting/repair steps fail or we need extra time to diagnose after class.


NOTE: Always submit a ticket in Solar Winds and be sure to assign yourself if you are responding. Don’t forget to set it to Work In Progress before you head out to resolve the ticket. Finally, be sure to close the ticket once the issue is resolved. If you can’t completely resolve it on the first trip, but you provided a temporary solution, please notate the steps you took in the ticket.

Host PC issues

If a client calls about no image/black screen on the projector, follow the following steps:


1. Check and reseat the AV connection to the laptop and wall or Podium


2. Switch to a different source, and see if it is doing the same thing

a. Remember that in BECC and Westlake, you have to select the new source, then send it to the appropriate device(s)


3. Power Cycle the system to verify that the projector is receiving control signals (It won’t turn off if it isn’t)


4. If none of the above work, be sure to have a projector cart handy to get the class moving while we look into it further.


Note: In the case that the above steps don’t work, we will need to return after class and do the following:


In Bradley and Westlake Halls:

a. If the projector is non-responsive to controls, then you will need a DM Receiver Power Supply from our stock in Morgan Hall.

b. The receiver and power supply can be found in the ceiling adjacent to the projector

Projector Cutting off Top and/or bottom of Image

If a client calls about issues with the projector cutting off at the top or bottom of the screen, do the following:


1. Change the source being displayed


2. Change the source back back.

This will force the projector to redraw the display and therefore fix the issue.


Note: This typically occurs in GCC, but can happen in other spaces.


3. Confirm that the laptop resolution being sent is correct.

Note: In most cases, it should be 1920x1080

Solstice Connection

If there are any issues connecting to Solstice at any desk/podium, do the following:


1. Confirm app is updated on computer / mobile device


2. Confirm that laptop / mobile device is on BU-Secure WiFi


3. Confirm that the Solstice is displaying on the screen


4. Powercycle the Solstice device by pulling PoE cable from the back of it and plugging it back into the unit. After this, ensure that the image displays correctly on the monitor with correct time and instructions for connections.


Note: In BECC, most of the PODs’ Solstice devices can be found in the AV Closet for each room.


Note: It can take up to 5 minutes to reboot.

Touch panel not turning on/off projector / Touch Panel not working

In the case that the touch panel doesn’t turn the projector on/off and/or the touch panel is non-responsive, do the following:


1. Check and reseat the ethernet cable (Power over Ethernet) from the panel.

a. On the small panels in WES, Olin, BR you will need to unscrew the base to access the cable


2. Reset the DMPS in the podium by unplugging and replugging power


Note: This can take 5 minutes or more to fully reboot both devices


3. If this doesn’t work, be sure to have a projector on a cart and HDMI cables ready so that you can get the class going until we can replace the appropriate devices


Note: For instructions specific to BECC, refer to the BECC Troubleshooting Guide

Document Camera Not displaying or Blurry

In the case that the Document Camera is not displaying, do the following:


1. Check and reseat all the cables to the back of the projector.


2. Change source to another one and back to the Doc Cam


3. Verify that all of the lights on the Doc Cam and controls on the touch panel are working


4. Verify that the HDMI or VGA coming out of the Doc Cam is working properly

a. Unplug it from the Doc Cam

b. Plug it into another source

i. If it works, move on to step c


c. Reseat it into the Doc Cam


d. Unplug it from the back of the DMPS


e. Plug a different HDMI/VGA from another source (i.e. Laptop, Host PC, etc)

i. If the previous steps work and you see images from other sources/cables, replace the HDMI/VGA cable with the working one


If the Document Camera image is blurry, do the following:


1. Press and hold the auto-focus button. This should force the camera to refocus.

If that doesn’t work, move on to step 2


2. Toggle the input off the doc cam and back on.
