odd noise on PAL S-VHS VCR used in USA

[lordsmurf]

I have a https://www.jvc.nl/product.php%3Fid%3DHR-S7965EK%26eshop%3D%26catid%3D48+HR-S7965EK&hl=en]JVC HR-S7965EK[/url] unit (PAL, made in Germany, imported from the UK), and using a VIC-100W voltage/power converter.

When I play tapes, either homemade home movies, or imported retail tapes, I get this kind of flaw:



What gets even odder is I can play some homemade Australian tapes just fine. There is no noticeable problem like this. But anything from UK is bad, as are retail tapes from anywhere.

No, this is not a copy protection issue. TBC has no effect. In fact the JVC's DNR/TBC has only minimal effect. The problem is DEFINITELY a chroma issue, which I have been told in the past could be related to power consumption.

I'm just seeking some outside ideas on how to fix this. Right now, while I can see the video and audio from my PAL tapes, it looks like trash with this flaw on it.

@ LS

Just out of curiosity..

Where are these artifacts showing up at ??

I have two 8965 units from the Uk, put a north american plugs on them, they work fine from 110 without a power converter.

I too have a JVC PAL/NTSC SVHS unit. It's a different model than listed here, but it has a UK plug but auto detects voltage. Just needed an adaptor for the plug.

vhelp, just what it shows in the picture. That image was supposed to be all black frame. That is made in Photoshop, FYI, but looks real close.

The back of the unit specifically says
AC 220V - 240V ~ 50/60 Hz
I'm under the impression that requires voltage converter, and that standard 100V-120V (USA) is insufficient. Am I wrong?

[victoriabears]

Basic info, plugging a 220v item into 110 cannot harm it, the other way round then yes it can - big time.

Cut it off and use a north american plug, blue wire goes to the thicker pin.

My stuff says 220 and works fine.

Just depends.

Must be cheaperr for these manufactuere to use worldwide transformers in bulk and just stick the country label on them

[lordsmurf]

I don't know about cutting it off, but I can go get a adapter plug for a few bucks at Radio Shack.

[victoriabears]

let us know if it helps, if you are not movnig to europe , may as well put North American plugs on it, two prong good quality are fine.

[lordsmurf]

My only reason for not cutting it off is I may someday want to sell it back off, and there is no guarantee it won't "go home" right back to Europe where I bought it.

I'll go try an adapter today.

[lordsmurf]

Well, that did it. The voltage converter was "dirty" power. It caused the noise I saw.

I went to Fry's and got two adapters. The first one turns the 3-prong UK into a 2-prong UK (nothing is lost here, as the third prong was only plastic). And then one to convert 2-prong UK to 2-prong USA.

The result is a JVC S-VHS unit that works as well as my SR-V10U does.

Thanks to the 7965 and 8965 owners that pointed me in the right direction. I guess that's what happens when you read the sitckers and believe them. 220-240V my ass. Indeed, it's a worldwide PSU, 110-240V

Its very nice to be able to help you, thats quite something.

Good Luck
