I have a CTS 1100 that's acting weird. By default, it should not display anything when it is idle, but it is displaying red, green, blue, yellow, cyan, pink, ash, and then black. This pattern will repeat all day long. Please see trouble shooting done below. I hope you guys could help me with this.
- Checked and reaseted the cables
- Rebooted the TP
- Connected VGA to laptop, display is OK
- Test call to other TP
This is a common "issue" it is displaying a test pattern.
I would recommend you to "reset" the screen, accordinly to https://supportforums.cisco.com/docs/DOC-25898 if
If the issue does not go away, then please try to play around with the two buttons - pressing one of them ( cant really remember which one ) will turn off the test pattern.
I did the same process a month ago, a new TX 1310-65, I do not know for sure what gen was, but I think it's the same process for all.
When I did, I had to do about 3 ~ 4 times to work.
