Panasonic NV-HS950 - how much trouble will it be?
I own precisely one video cassette recorder, this Panasonic NV-HS950 which was given to me in immaculate condition about 15 years ago. I rarely use it but like to have the ability to play VHS tapes when occasion demands.
A couple of weeks ago I tried to use it but find it won't accept a tape, and behaves as if something's slipping inside. I haven't yet investigated what the fault is. This machine has all the bells and whistles, is in immaculate condition, and has performed very well in the past. My question is: how much of a nightmare is it likely to be to get working reliably again? Anyone here know if these machines suffer brittle plastics or surface-mount electrolytic plague? I'd like to know what I'm letting myself in for... Thanks Chris

Re: Panasonic NV-HS950 - how much trouble will it be?
I would say it is most likely the small plastic coupler on the mechanism loading motor shaft. it's a push fit onto the shaft, and over time the plastic splits causing reduced or total loss of drive. I have replaced dozens of them in the past, they can be a little tricky as access is from underneath the transport. Because it was such a common fault I suspect there will still be some lurking in a spares drawer somewhere.

Yes, the the K-mech was covered in the November 1993 edition of Television magazine, which can be downloaded from here. Naturally, YouTube also has some videos..of videos!

Re: Panasonic NV-HS950 - how much trouble will it be?
Or is it the Z-mech? The loading motor coupler is a white, Nylon(?) part which is a friction fit on the loading motor's spindle.
It has been suggested that any replacement should have its bore enlarged slightly, then attached with Superglue, to prevent an early recurrence. Good luck in finding one though; when I repaired mine 5-10 years ago, they were extremely hard to source. Possibly... https://www.donberg.co.uk/catalogue/.../vdp_1434.html |

I'm sure there's an enterprising person with a 3-D printer...

Chris,
As has been mentioned elseware on the forum be aware Donberg have a minimum order value of 50 Euro's. If you intend to repair your Pana, and it turns out to be the coupler let me know and I will check if I still have one. Les

One trick I've found that works is to roughen the motor spindle with a file or course emery paper then use araldite to glue the pulley onto the motor shaft. |
