I spent 35 years as an electronics engineer. Over my career like most of the guys I worked with, as a "fiddle" we diagnosed & repaired equipment like this as well as TVs & audio gear. It is strange to think stuff used to be made to be stripped down & repaired like this...so many parts, all of which could be bought from firms like CPC...& great big thick service manuals with full schematic diagrams. Not like the crap they make today which is specifically deigned so it cannot be repaired.
great video and very helpful. I have not repaired a deck in decades and as a favour to someone agreed to repair their Panasonic NV-FS200B which is very similiar however there is an additional motor and toothed belt.
Thank you so much, i recived a FS100 HQ working properly till i put inside for the tthir time a cassette and started to do noises, i intented yesterday to align using this video but failed by a bit, this weeked i will atempt to fix it for the second time watching this video! Thanks a lot!
Massive thanks for the upload, i have one working nv f55b and 2 that are faulty this will enable me to hopefully build one good machine out of the 2 would never had known what to do had it not been for this video life saver ,thanks again
I have always been fascinated by the G-Mechanism, about 20 years ago i had two of these decks, and i didnt fully understand how this worked, because the loading was also been done by the capstan motor. One deck was mis aligned when i got it from a friend of mine, and it puzzled me how to align this mechanism. (i was only 15 at the time). But i did trial and error alignment so much on the mechanism without those holes or arrows pointing at each other. Because i didnt know what those holes or arrows were and never noticed. I got to a point where i could do the alignment of the G-Mechanism with my eyes closed and without referring to any holes or arrows. Infact i saw a Panasonic NV-J1 for sale today and i called the other and later i will buy it, brings back good memories with this mechanism. Thank you for sharing your video
Very Mr. Mio: I asked you a question and apparently you have not been able to answer me, I know that the power supply is not the fault, it will be due to the lack of alignment of the gears, I want to ask you another question. Inside, how do you move the tape guides so that everything is repositioned? Thanks for your videos.
Buenas noches, tengo un vídeo muy parecido a ese, es el nv j35 el problema que tengo es que el vídeo se desconecta porque la cinta no entra, le he cambiado todos los condensadores De la Fuente de alimentación, pero la tensión de 45v está en 43v .¿ Puede que sea eso el motivo? Una aclaración cuando le doy para ponerlo en marcha del botón de encendido ,no enciende ,pero si le doy del mando a distancia sí enciende aunque la cinta sigue sin entrar. ¿ Que puede ser ? Gracias.
I believe there is an error around 36:14. It is not the first but the second tip of the cassette holder rack which must align with the mark on the connection gear. The Panasonic manual is absolutely right, I have installed it this way several times. It maybe that the second tip is the first one which is visible through the hole when looking from the top. But it is definitely the second tip of the rack.
The G10 doesn't use the G mechanism. It uses the older D1 mechanism. Clean the mode switch and check the rubber parts (loading belt, reel drive belt and idler).
Thanks for posting this video - Very helpful in getting my Panasonic AG-W1 working after 4+ years!
Maravilloso elvideo era justo lo que necesitava para la reparacion de mi vhs.Gracias!!!

paulb4uk Glad it may help you. The F55 is well worth fixing - has the best version of the G Mechanism and excellent picture and sound. Good luck!
Gran reparación
These were a nightmare to do a gearing rebuild on, one tooth out click click click 🤯🤯🤯 lol

yep but how many times did you realign these decks then quickly put in the cassette mechanism being one tooth out
Thanks for posting this video.
Anyone has a tutorial for a K Deck VCR unit? Presently trying to re-assemble a Panasonic VD-HD100. Thanks.

How dose it play without cassette?
Any idea what is the type of mechanism on fs77 and fs88/fs200? It looks like G but has an additional motor
I think that mechanism is G2 like the guy says in the video
@@sos.gamers I missed it on the video but yes, its G2, managed to rebuild it
Smps power,,,dc,,output voltage level,, please Sir,,, VCR national,, j1 model
Where does the video come from? When it has been filmed?
Mr Magnétoscope It was made by Panasonic UK to help engineers who did not fully understand the mechanism.

Oh, cool.
plzz help me i hav national G10VCR bt thats not playing & not rewind and forword the cassate
plzzz help how to solve the mechanisim timing problem
