I have a Panasonic NV-9600 3/4" U-Matic deck that won't eject. Got it on ebay
for 350. All lights come on, keys work, etc. Bought the weird power cord, and tried to get a tape in. Come to find that the eject key just flashes and makes a whining sound.
I've made a YouTube video demonstrating the problem.
Also, looking from the back of the VCR, is the right pin on a three-prong oval connector usually the hot wire? How would I be able to tell if the polarity was wrong? I have determined that the right plug on my female oval connector, again, with the plug facing the VCR, is the hot one.
I have to ask all this because even through all the service manuals for these panasonic u-vision machines, I cannot find any indication of which of the wires is hot and cold. I think the machine might not be ejecting because the polarity could possibly be wrong. I read that HP, way back in the 60/70's had some variation in the polarity of their power cables.
It's certainly at the right voltage though, 120. Checked it with a multi-meter from both the AC socket itself, and from the power cord. It's also dialed in correctly on the VCR's adjustable voltage switch. I marked the power cord correctly with red sharpie just in case I forgot. I still, however, cannot determine if it's the correct polarity for the VTR itself.
Also, do these VCR's use more than 7 amps? Is it OK to use a cable marked at 125v, as shown in the video, with a 120v outlet? Will the VTR not function properly since it's so close to voltage limit of the power cord?
