2￿Troubleshooting￿Procedures￿

The￿Camera￿board￿or￿system￿board￿may￿be￿the￿reason￿of￿a￿Camera￿fault.￿Either￿of￿these￿two￿

components￿may￿be￿damaged.￿To￿determine￿if￿the￿computer’s￿Camera￿is￿functioning￿

properly,￿perform￿the￿following￿procedures.￿Figure￿2-14￿outlines￿the￿process.￿Start￿with￿

Procedure￿1￿and￿continue￿with￿the￿other￿procedures￿as￿instructed.￿

Procedure￿1:￿ Diagnostic￿test￿

Procedure￿2:￿ Connector￿and￿replacement￿check￿

Procedure￿1￿ Diagnostic￿test￿

Run￿the￿functioning￿Program￿in￿windows,￿which￿will￿display￿the￿Camera￿test￿result.￿

If￿tests￿and￿diagnostics￿result￿abnormal￿go￿to￿Procedure￿2.￿If￿an￿error￿is￿not￿located,￿the￿ Camera￿system￿is￿functioning￿properly.￿

Procedure￿2￿ Connector￿and￿replacement￿check￿

The￿Camera￿board￿or￿system￿board￿may￿be￿disconnected￿or￿damaged.￿￿Disassemble￿the￿ computer￿following￿the￿steps￿described￿in￿Chapter￿4,￿Replacement￿Procedures,￿and￿perform￿ the￿following￿checks.￿

￿

Check￿1￿ Make￿sure￿that￿the￿Camera￿board￿cable￿is￿securely￿slotted￿into￿the￿system￿board.￿ If￿the￿problem￿persists,￿go￿to￿Check￿2.￿

Check￿2￿ The￿Camera￿board￿may￿be￿damaged.￿Replace￿it￿with￿a￿new￿one￿following￿the￿ instructions￿in￿Chapter￿4.￿If￿the￿problem￿still￿exists,￿perform￿Check￿3.￿

Check￿3￿ The￿system￿board￿may￿be￿damaged.￿￿Replace￿it￿with￿a￿new￿one￿following￿the￿ instructions￿in￿Chapter￿4.￿
