Hi All, Customer complained that C-Touch was only responding occasionally and when it did very slowly. We did the disaster recovery routine, but were unable to get much past the boot routine. To try to eliminate possible issues with the install, the screen was brought back to be bench checked. (different PSU) With further testing, initially it seems that everything is fine until it warms up, the backlight and screen intermittently flashes and response is slow if at all. I reset the screen and the following error is generated: [I]"Error communicating with auxiliary processor. Error "No response" with command "Initialise"[/I] The unit is about 3 years old, but only installed about 18 months ago (construction delays), it has no schedules or scenes and only a small amount of logic. Does anyone know of an issue like this and what can be done to sort this out? Thanks Michael
