An electronic device having a faulty touch panel may be diagnosed and indicated for repair by extracting a log from the electronic device. The log may include a record of touch panel events indicating active and inactive touch panel events divided into time periods. The log may be analyzed for touch panel events in a given time period. If a total number of touch panel events in a given time period exceeds a threshold count, and if a percentage of touch panel events in that given time period exceeds a threshold percentage, the touch panel may be identified as in need of replacement. Further, if a total number of touch panel events for all time periods exceeds a threshold percentage, the touch panel may be identified as in need of replacement.
