Horizontal stripes on play back

I take the cover off the door, using the eraser as the end of a pencil - lightly press on the recording head (drum). Put a tape in and watch to see if the tape now wraps around the head and stays in position to record.

• Like all the old video recorders there are mechanical parts inside what need cleaning in high priority the parts that mechanical activate switches for the intake in the little microcontactsswitches and the most important of all are mechanical mode-select-switches where timing is an hot issue
  
• The entire process is timed often gears are used, but sometimes also strings that can slip by age and or dirt, cleaning and contact cleaner and look for bad soldering.
• Also check that the lens motor for the aperture setting is working properly, because everything concerns mechanical settings when that failure then stops the device.
  Also the zoom lens motor that are the first mechanical parts after the tape was lace in. all must exactly done in a special short timing.

Blue stripes in playback is an indication that you need to clean the heads. A Panasonic cleaning tape should work fine.

Panasonic lists video heads for the AG-DVC7 at about $250.00. p/n VEG1576.

Your playback heads might be clogged. I am not sure if this camera with give you a RF warning if your record heads get clogged. Also most professional machines drums are rated at 1000 - 1500 hours before they need to be replaced. If you are at 500 and never cleaned the heads it is time to. Run a cleaning tape a few times.

Hello, please try to clean the head with mini DV tape cleaning cassette. Best regards. Arpi

you may have a slightly damaged power supply...although swapping the main supply chassis may solve, I have seen front panels that have an additional supply section. look on the front panel board for any TP's and probe with an O-scope. if you see a TP that may also show (+ xx V), where xx is a numerical value-may be one x only, the scope must show a straight horizontal line that is shifted vertically away from its normal (ground) position. that confirms a DC value present. then determine the DC value of the shift. Another possibility, since you invested, is to search ebay for a second unit for part swapping. look for as-is units.

I've had this happen with a Panasonic when I went back out into the cold after going into a warm, humid cafe for lunch. The drum had picked up some condensation, but the condensation detector didn't shut down the camera.
