[CA] E wide touchscreen not responding

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum John,

Should the MFD's TouchLock feature not be enabled and should the reported symptoms occur, then it would appear that the MFD has suffered a failure of its internal circuitry, necessitating that the MFD be sent to Raymarine’s Product Repair Center to be bench checked / serviced. That said, you may want to try performing a Factory Reset Operation as a last measure to correct the problem before sending the MFD to in for service.
