Procedure￿1￿ TV￿tuner￿Cable￿connection￿check￿

The￿TV￿Tuner￿cable￿may￿be￿damaged￿or￿the￿connections￿may￿be￿loose.￿Use￿windows￿ application￿to￿check￿device￿can￿work￿fine￿or￿not.￿If￿an￿error￿is￿located,￿Perform￿Check￿1:￿

Check￿1￿ Make￿sure￿TV￿Tuner￿cable￿is￿firmly￿plugged￿into￿both￿the￿TV￿Tuner￿set￿and￿the￿ TV￿Tuner￿port￿of￿the￿computer.￿If￿the￿cable￿is￿connected￿correctly,￿go￿to￿Check￿2.￿

Check￿2￿ Make￿sure￿the￿TV￿Tuner￿port￿is￿firmly￿secured￿to￿the￿system￿board￿of￿the￿ computer.￿If￿the￿malfunction￿remains,￿go￿to￿Check￿3.￿

Check￿3￿ The￿TV￿Tuner￿cable￿may￿be￿damaged.￿Replace￿with￿a￿good￿cable.￿If￿the￿ malfunction￿remains,￿go￿to￿Procedure￿2.￿

Procedure￿2￿ TV￿Tuner￿SG￿setting￿check￿

The￿TV￿Tuner￿SG￿setting￿may￿be￿faulty.￿Perform￿Check￿1:￿

Check￿1￿ Check￿the￿TV￿Tuner￿Setting￿was￿right￿or￿wrong,￿if￿right;￿go￿to￿check￿2,￿if￿wrong.￿ Correct￿it￿and￿re-test.￿If￿fail￿symptom￿still￿exist,￿go￿to￿Procedure￿

Check￿2￿ Try￿connecting￿a￿different￿TV￿tuner￿SG￿to￿the￿computer.￿If￿the￿replacement￿TV￿ tuner￿SG￿works,￿the￿original￿set￿may￿be￿damaged.￿If￿the￿replacement￿set￿does￿not￿ work￿the￿TV￿tuner￿Antenna￿may￿be￿damaged.￿Go￿to￿Procedure￿3.￿￿
