    How to fix a blurry image on Sony DCR-TRV820 viewfinder screen?
    • M
      Mario MarquezAug 20, 2025
      If the image on your Sony Camcorder's viewfinder screen is blurry, try adjusting the viewfinder lens. Also, make sure that STEADYSHOT is set to ON in the menu.

    Why does the START/STOP button not operate on my Sony Camcorder?
    • K
      Karen WilliamsAug 23, 2025
      If the START/STOP button on your Sony Camcorder isn't working, there could be several reasons. First, ensure the POWER switch is set to CAMERA. Also, check if the tape has run out, and rewind or replace it if necessary. The write-protect tab might be exposing the red mark, so use a new tape or slide the tab. If moisture condensation has occurred, leave the camcorder for an hour to acclimatize. If the camcorder has been in standby mode for over 3 minutes, set the POWER switch to OFF (CHARGE) and then back to CAMERA. Adjust the viewfinder lens if needed. Ensure STEADYSHOT is set to ON in the menu settings and FOCUS is set to AUTO. If shooting conditions are unsuitable for autofocus, set FOCUS to MANUAL. Cancel any active digital effects. Finally, close the LCD panel.

      If your Sony Camcorder is shutting off unexpectedly, it could be due to a disconnected power source or a dead battery. Ensure the power source is connected and use a charged battery pack.
