We have EX90 endpoint with touch panel and it worked fine before someday there is a problem had occured, the touch panel just displays cisco logo and flashing volume bar time to time, not responding to taping on it. Please if somebody know this kind of issue what is the problem?
Codec version TC188.8.131.525220, there was no any recent update, yes EX90 when boot up - there is wallpaper, but on touch panel 'cisco' logo only. I tried booting EX90 without touch panel, then pluged in, all the same.
Is the touch panel the one that came with the system? If not, or, if it's one of the newer touch panels, it may require a more recent version of the codec software to function (The newer panels need TC5.1.4 or higher).
There's a Hardware Dependencies appendix at the end of the release notes for the TC software that specifies the minimum firmware versions for the touch panel and codec to function correctly and how to identify which one you've got by it's TAN number.
Given that the software is up to TC6.2 now, perhaps you could try upgrading your EX90 to a newer version and this could fix your issue.
