A small percentage of 65" TelePresence displays (CTS-DISP-65-GEN2[=]) with specific serial numbers shipped between December 15th, 2008 and August 2nd, 2009 can show reliability issues and symptoms such as a permanent blank or flickering display image. You can check your serial number online.
The Telepresence 65" display uses an internal cable to transport video signals from its controller board to the glass. Recent shipments from a sub-supplier show manufacturing defects that can cause display problems seen in the field. The issues are only seen on a small percentage of displays shipped between December 15th, 2008 and August 2nd, 2009.
Affected units are in this serial number range.
Complete these steps in order to locate the serial number (SN) of your system:
- Log into the Admin CLI of the CTS system via SSH.
- Run this command in order to get the SN and Model of the plasma display:
admin: show hardware video
Note: Displays in the specified serial number and datecode ranges that have a deviation sticker affixed are NOT affected.
A small percentage of shipments between December 15th, 2008 and August 2nd, 2009 of 65" TelePresence displays (CTS-DISP-65-GEN2[=]) can show these reliability issues in the field:
- Flickering: Unit flickers rapidly for a short duration and usually corrects itself. During this time the image can scroll rapidly and have a blue-ish snow-effect.
- Blank-Screen: A functional plasma can cease to show an image (either during a call, or at startup), while the LED indicates GREEN/'OK'. The unit never resumes normal operation. It does not help to factory-reset and/or reprogram the unit, but the Codec within the TelePresence system is still able to communicate with the display.
Use the standard RMA process to replace a defective display.
Replacement of a defective display typically takes two or more days depending on the location of the TelePresence system and the availability of repair parts and personnel. This option does not expire.
