CANON ZR65 will not turn on - battery charged AC plugged in

This is a known problem.
Broken loading gear, Example: canon zr65 replace broken gear
Canon XL2 and ZR65 uses same tape drive system.

Batteries have electronics data that software has to get to properly charge it. Newer lithium batteries maybe different. But apparently, you have a work around for a lengthy use of the new battery.

Can you not detach the lead to the charger unit, and plug that directly to the camcorder, to see if its the actual camcorder at fault ?
Near the camcorders power socket, you should see a small picture telling you what power the cam uses - usually around 7 volts, centre positive connection jack plug, at around 900mAh. As long as you get the voltage close, and have enough amps behind it, it will still work safely.
Camcorders are rarely fussy about the exact voltage, but you should never go above 9 volts unless its needs more. Most take the internal power down to 5 volts inside anyway.
The batteries do have a tiny non-replaceable internal fuse, triggered by voltage spikes or overheating, and if that goes, it usually means buying a new battery :(
Batteries can go at any time from the very first second they are used. I've bought many, and had a few that didn't last 2 months from brand new. One high-end type lasted over 9 hours on its very first charge :) and then never worked again after that :(

I would guess that ur battery is bad and will not hold a charge. Try a new battery and see if that fixes it.

electronics should not be relied on to realy confirm u need to use a second battery pack to connect ur printer n see if the same thing will occure. i guess the battry inside d pack may be dead even though its a new one.

ZR85 WILL NOT TURN ON WIT OR WITHOUT BATTERY?

can this camcorder (canon ntsc zr65 mc ) can the video be downloaded to my mac laptop?

The CCD is not involved with playback, only the read heads. Your CCD could indeed be faulty. If the audio failed, it likely has circuit board issues which may affect the CCD even though it is working.
