the problem of your player is the mechanism to dv tape slut(not mini dv)...it need to calibrate or to tune up...only can fix this is a qualified technician....
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.
I believe that this error message indicates that the heads are not spinning. The tape should be ejected. This unit requires a servicer. There are a number of reasons for the heads not spinning. Finding out the cause in your specific unit will require testing and measurements with test gear. There are no user serviceable parts inside these units. Please see an authorized Panasonic service center.
timing the AG-1970 is best done with a service manual. it has several diagrams in it which show how to time the gears. it may still be available from Panasonic.
the "dv sensor"is actually a mechanical lever built into the cassette
housing that moves the reel tables to match the reel spacing on mini or
full-size DV tapes. check to see if this assembly is free to move. if
it binds up, the reel tables may not move as far as they need to, and
can cause problems similar to the one you're seeing. to inspect the
mechanism, you need to remove the cassette housing. if you don't have a
service manual, get a tech to help -- it's a delicate procedure for the
inexperienced.
