Thank you for posting the three vlog's about the repairability issues of the Panasonic AG 1970 🙏. I have the european model NV-FS200 with similar problems. The outcome from your investigation helped me a lot to understand the root cause in my device. Before I decide whether I keep or throw it I have to look if there's any chance to find replacement capacitors. I'm a litte bit stubborn as I want to try to restore my VCR in good working order.🙂
I repaired a lot of Panasonic NV FS200 (PAL model of the 1980). I always spent like 2-3 complete days to fix one of them properly. At the end 99% of the people won't pay you for this kind of extensive work.
You are absolutely right... i'm currently rebuilding an Nv-Fs200 my self because i haven't found someone expert to fix it. So i ended up with a service manual and a box of capacitors. As you said and some more 4 complete days (day/night) it took me...due to lockdown i have lots of free time as you can see.
@@qwiX I found that out the hard way ..because i had almost zero knowledge or expirience fixing vhs maxhines...i was a kid when these where on the market .Just had it for years in storage almos dead with nearly b&w picture and out of sync mechanism ... i thought i bring it to life so i did (the only problem is that on some tapes the picture wiggles sideways but if you let them play for some time corrects it self..not a clue whats that about) Anyhow...thats why i related when i read your comment. Keep up the good work if you are still in to this.
Same here. I have a bunch of AG4700 and HS1000 that I have rebuilt. Working nicely now. Now I got a couple of FS88 and a FS90. I was waiting this video from Dave to see how he gets to the mode switch since I never worked with these models.
@@MarceloJavierMazaLuparia In his channel he has at least one video cleaning that mode switch whithout the need for reallingment but thats on a Z-mech panasonic deck. check it out.
I used to hate working on that series of mechs too. Mode switch goes dirty and you end up with a small pile of broken plastic junk levers sitting in the mech. Or split the cassette holder plastic side pieces/ pins. I remember thinking this is it. Even vcrs are now plastic crap mechs
They throw em away here left right and center. I have 5 just sitting waiting to be put back in service, and 5 currently in service. The plasma on my work bench is a very old SD plasma. I have a 43HD on my edit computer.
So my NV-FS200 (European clone of this) finally bit the dust yesteday. I did not realize how dark the picture actually was until I tried another VCR. Then the FS200 started shutting itself down in the middle of digitizing. I decided not to recap the PSU because of the bad picture. I also found that the vsc2911 module is about to go and cannot be replaced anymore. I will maybe put the VCR on the shelf or just scrap it, don't know yet. Come to think of it, it probably was not worth the money I had spent on this. I bought it for roughly 150 CAD as a non-functional unit and squeezed almost three more years of life out of it. I wanted that TBC sooo much. It really makes a difference...
No because I am not continuing on this one. It was purchased by a company that does video archiving and I don't think this is a good candidate for this task as the picture quality isn't great and with all those caps on those modules going south i can't recommend dumping a bunch of money into this one. It is very old and these ones were not great to begin with, reliability wise that is.
Since the Y/C module on this one still hasn't gone kaput, meaning the electrolytics still haven't ruined the resistors, would it be possible to recap the module with decent caps or it's just too much hassle ?
what do you do If a Panasonic vcr records and you play it back with a grainy black and white picture with no audio. It will wipe the tape then move onto the heads where it does nothing. I've tried cleaning the heads and all the other parts that come in contact with the tape but it will still produce a horrible picture. all i know is that i have another vcr that is a sansui vcr/ tv combo that can be placed inside of a car plays and records the tape with absolutely no problem. Also the vcr plays back other tapes that i recorded on the sansui vcr with little or no problems.
It did seem to produce a watchable picture, not bad considering it's age. I always hated the multiregulator black modules, some of the video stars had them. It was not a cheap chip at the time :-(
Possible, yes. Worth doing though, when the flex cable to the panel will fail next? Also chances are even though it's working currently, the caps have already begun to leak and destroy the TF resistors. Again, if one was determined enough they could repair these but it's a question of if it's worthwhile.
I was checking that Tgrant photo offers full repair of the Panasonic AG1980 (Mechanism Repair + Replace Bad Caps + New caps) for around 600usd. I would take that money to get a JVC HRS SVHS instead.
Agree. I have one without TBC sadly but with a very good transport mechanism (HR-S6800U) based on recommendations from digitalfaq repair buying guide. It did eat tapes but a little bit of cleaning and minor lubrication fixed that straight up. The output quality is top notch, even with pretty poor prerecorded tapes.
@@MarceloJavierMazaLuparia From my understanding about the subject, a standalone TBC cannot possibly do the same job as the one built into the VCR itself. You could probably achieve the same thing with software post-processing. For me personally it is not interesting as this more than fit the bill to restore a handful of home videos for a $50 ebay buy. And the other day I actually found a D-VHS deck in our local building's trash but it only had quasi-SVHS and the deck itself otherwise is nothing special so I left it there.
@@stragulus Sorry but you have a wrong idea. Standalone tbc vs built-in, the standalone is usually better. The built in can be glitchy or do little time-base correction. Generally the JVC's built-tbc works better than Panasonics. Software-based tbc doesnt exist perse, also the important thing is to have a proper capture withou dropped or inserted frames, and you cant do that if you dont have a proper TBC. You cant solve that with software.
@@MarceloJavierMazaLuparia I see, seems my understanding is lacking. From a quick glance it would appear that both TBC in the VCR and an external one could be beneficial. I'm not a video archive expert nor do I aspire to be one though :)
Come on who didn't want to be a radio pirate in high school? Wait a minute! I was. Took a Mr Microphone and cut a perfectly matched antenna to it. Changed the transistor to a higher voltage version and fed it with 12 volts. Got a little over 1/2 watt out of it and covered the entire town nicely.
@@12voltvids It probably wouldn't be cost-effective but how possible would it be to remake the module on a regular board, replacing the printed resistors with regular ones? Then again there's probably a reason they used glass boards in the first place, so maybe it wouldn't work.
Thanks for another great video 👍😃 absolute garbage machine full of smd "Crapacitor" 😅 yet everyone is still recommending these unit online and eBay prices are a joke 🤣🙈 I bought my first ag 1960 (NV FS 100) 5 years ago and had to buy 3 other machine just to get mine going, as soon as you fixed something, another thing is breaking, it's an endless loop. And now for the 3 time ic301 in y/c board is failing again, stupid surface mount capacitor and unfixable pcb with these printed resistors 🤮 now I'm just sticking to my modern JVC svhs deck, reliable, hardly need any service, and the picture quality is just as good, and I get a TBC as well 👍
@@Synthematix Yup, tape sucks, always has, always will, but some brain dead people believe that it is better than digital formats. These same brain dead people also think dragging a rock through a grove in a piece of plastic rotating at 33.3 rmp will give a better sound that a digital recording. Some of these brain dead people will spend tens of thousands of dollars striving to get even better sound from this rock being beat up in this record groove.
@@12voltvids Vinyl sounds absolutely better than almost any digital format. Airiness, musicality, bass etc. You have not heard a good turntable and riaa combo if you say it like that.
@@petrileskinen4299 I have a few great turntables. Thorens and technics with proper tube preamp and tube amp. They sound great however i also have a real cd player, not a cheap 20.00 cd player and the cd bests the vinyl any day and twice on Sunday. Now some CDs were absolutely garbage. The engineer was tone deaf i aware, but a properly mastered cd will destroy anything on any analog format. Keep in mind that many CDs were just recorded from a vinyl copy or from an analog tape that had been eq and dynamic range limited as the tape was made for vinyl or cassette replication. If the studio did a proper digital mix the sound was superior. DDD was the best, all digital all the way. Next best was ADD, analog session tape, digital mix and digital master. AAD, analog session, analog mix and the D Is the digital copy. It makes a big difference. I listen mostly to jazz and those guys were early adopters of full digital sessions and it really shows.
It might be worth keeping the mech and head drum assembly (if it's not shot like the one in the other video), the mech is used in a bunch of other panasonics from the time, and the drum assemblies are cross-compatible to a degree between panasonics with similar head counts from around the same years.
Do you know if a Secam-l TBC exist ? I can't find one and all my tape I need to digitalize are Secam since I live in France 🤔 The TBC in my JVC svhs only work on Pal tapes 😭
SECAM is trash and a pain in the butt to deal with, and was never supported by S-VHS. Transfer your tapes using a domestic French SECAM VCR (not MESECAM) and an external time base corrector. The NV-FS100F S-VHS machine supports both SECAM and MESECAM but doesn't have a TBC.
@@crashbandicoot4everr I live in France so all my vcr can play Secam L. I have a number of s-vhs decks including the absolute garbage fs 100, and two JVC with TBC, HR-S7600MS and HR-S9500MS. But I need to find a TBC that will work on Secam tape not only PAL
