Common fault 1: Unable to record normally

The fault phenomenon is that after pressing the record button, there is no recording symbol on the LCD and the DV tape does not rotate.

Fault analysis and troubleshooting methods: Tape problems or circuit damage, the troubleshooting methods are as follows: A. Remove the tape and observe whether the write protection film has been removed. If this is the case, use tape to block it. Just close the write-protect hole. B. If the tape has reached the end, it can be used normally after rewinding; C. Replace the tape to rule out tape damage; D. If the above method is ineffective, it may be a circuit failure and send it to a digital camera repair station for testing.

Common fault three: unable to boot normally

Fault analysis and troubleshooting methods:

A. The battery is dead, the battery is damaged, or the charger is damaged. In this case, you can charge the battery first, or check whether the charger is in normal charging status. Another way is to take it directly to the repair station and borrow the battery or charger from the repair station for testing. Generally, there is no charge in this case.

B. Automatic camera protection: There are generally two reasons for automatic protection: Reason 1: There is water vapor inside the DV or on the DV belt. Do not force the camera to turn on at this time, otherwise it will easily damage the magnetic head. The author I learned from the Guangzhou Southern Digital Imaging Repair Center that the correct treatment method is to use a fan or a hair dryer with a cold wind setting to dry it. After it is completely dry, you can start it up and use it normally.

C. There are serious scratches on the surface of the DV tape. In order to protect the magnetic head from damage, the DV machine automatically shuts down. The solution is also very simple, just replace the DV tape.

D. If the above items are excluded, you can only send it to a digital camera or video camera repair station to solve the problem.

If the image on the TV screen is normal, it means shooting There is no problem with the part, the problem is with the viewfinder. Send it to a digital camera repair center for inspection.

Common fault five: The screen dims or does not display

Fault analysis: The screen does not turn on or the light bulb behind the screen is aging

Troubleshooting method: A. Replace and check the screen Is the switch on? B. Connect the TV video. If the video can be displayed normally, it may be caused by the aging and failure of the bulb on the back of the LCD.
