Dental Chair Video Screen arrangement

Question

How do I fix the 2nd screen on the Dental chairs in the Clinic? It currently is displaying TV static.

A Samsung TV screen mounted on a dental chair arm showing black and white 'snow' or TV static.

Environment

  • Cook Academic Hall Dental Clinic
  • Dental chairs
  • Samsung TV display

Information

These arm-mounted displays are small Samsung TVs. The display can accidentally be set to a "TV" input. Since there is no coaxial signal, it will display static instead of the PC feed.

Info: Input Selection: Ensure the PC is powered on before attempting to switch inputs to ensure a signal is detected.

Answer

There are two methods to switch the input back to the PC selection:

Method 1: Manual Toggle

  1. Press the menu toggle button on the back of the display.

Method 2: Control Box

  2. This is controlled by the control box wired into the system, located next to the counter display.
