Customer Question

I saw the reply you gave to Basil 4 years ago about his Panasonic camcorder NV-S85. I just bought one second hand so I can digitise my old SVHSC tapes. There was no dc power lead and both batteries seemed dead so I tried to charge them. This put their voltage up to 5.6 but whether they provide much current I don't know. When I use them on the camcorder the red camera light flashes, it refuses to be switched to player mode and there is no message, only a dim light in the viewfinder. I tried the method you described but all the screws were in different paces and numbers and I couldn't get any covers off to check inside. I cant understand this because it is supposed to be the same model number (NV-S85). Could the problem be just the batteries or is there anything else I could try? Many thanks, ***** *****

Good morning Del,

I am Tech Michael, I have been a hands on technician since forever lol.

My hobby is building intelligent robots so I always had a love hate relationship with all electronic devices.

In this case I do know your unit well. You are on the right track, the supply is bad. it will show the correct voltage 5.0 vcd, but it can not sink the current. In essence there is only a ghost voltage with no push behind it.(current as you mentioned).

With this you would do well to replace the power supply.

If you want you can try repairing the one in the unit but that will require a lot of testing. If you do want to do that I will help as much as possible from my end.

Also I may be able to locate a new supply board for you.

In any case, I will stick with you until this is complete.

Please rate kindly thus far, it won't cost you anything to rate my service to you kindly,

Then you can reach me by simply replying to this message anytime.

Thank you and have a wonderful day!

Just to be clear, by the power supply, am I right to think you are referring to the battery charger unit (which doubles as a power supply if you have the right lead) supplied as a separate item with the camcorder? I've been unable to test it directly as I was not given the dc lead that connects it to the camcorder. But I assume you mean that it is not charging the batteries properly. The voltage I quoted before was the battery voltage, I just checked the battery charger itself and it gives 5.1v between the + and T pins and a voltage fluctuating between 0.1 and 6.9 and 10.8v between the + and - pins. I just bought a new battery but it made no difference. I'm not sure now whether to buy a new charger (it seems none are ever supplied with the dc lead I need) or give up and look for another second hand camera.
Thanks

Hi Del, thanks for that info.

Yes it may very well be the charger supply unit.

But it could also be the internal supply in the camera, in this case, I would replace the camera or send the camera and charger for repair. The voltage reading you are getting are not normal so I would say that the charger is the source of the problem. They will wear out and sometimes become damaged by electrical spikes in the line voltage. They aren't very well made I'm afraid.

You can get a new charger and cord as I would in this case from this site:

In any case, I will stick with you until this is complete.
