I am trying to repair the same VCR. Where did you find the parts and repair manual?
Very neat combo of analog and digital!
That's pretty cool that it shows the seconds, but too bad it only shows them when setting the clock. In the 1980s, there were some calculator watches that would show the year when you _set_ the date, but would not show it when you pushed a button to _view_ the date -- to see the year, you had to enter date-setting mode! That VCR has linear stereo with Dolby noise reduction. I think it is from 1982, and NTSC-M TV was not yet in stereo at the time, so the VCR does not have a stereo tuner. Does it have an "MPX out" port on the back so one could connect an external TV-stereo decoder (when a TV stereo standard was established)? Sony's Betamaxes from the early '80s (like your SL-5200) have one.
I found a picture of the back of this VCR on an auction site. No, there is no "MPX out". All it has are antenna connectors (both 75Ω and 300Ω), RCA connectors for video and stereo audio in and out, and a "camera remote" connector. (Curiously, the right-channel audio connectors are labeled "audio dub", suggesting the audio dub feature only affects the right channel.) This is not unexpected, however. I have a high-end Panasonic stereo VCR (PV-1730) from 1984 with _both_ linear and hi-fi stereo but no stereo tuner, and it doesn't have an MPX out port either! It seems Sony may have been one of the few companies to provide this feature. The family of my best friend in high school had a Zenith VR-3100 VCR made by JVC, and it also had linear and hi-fi stereo but no stereo tuner and no MPX out port. To allow my friend to record from TV in stereo, I had to loan him both an external decoder _and_ a TV tuner because the decoder could only decode from an MPX port or channel 3. He had to tell the rest of his family not to touch the TV or VCR during this time. (They touched it anyway and messed up the audio on two of his recordings.)
Hey i have this same model, it only plays a blue screen i bought the remote and everything i dont know whats going on any idea?
3 heads were called "2 heads with a trick head." Hitachi whether you like them or not made incredible vcr's. Some say the best..nice video!
In Europe, we use a HDMI to Scart scaler. It seems to work well, but only for movies.
I just wrote a test card screen in PIL for python (so the throw blanket totally resonates.)
I’m still having trouble boss
I want it. I need it.
my dads friend has the stereo model of this mint condition in there basement next time im there I wil try it it has not been run in a long time
That beast doesn't half remind me of the various top-loader Ferguson 3v29 & 3v30s I'd lived with over the years in the 90s, but then, they were JVCs (HR-7200 & 7300 I think) rebadged as Ferguson models, so, they're related I suppose...
7:04 "ELNA" in the copper layer... did they do board manufacturing too? I thought they were just a capacitor company. Huh!
yes they did
Apprezzo il montaggio del nuovo display sulla scheda d'origine,cosi hai mantenuto tutto il setup originale,compreso il led audio rec. bel JVC!
That's super cool, I bet that was a REALLY expensive bit of kit back in the day.
I suppose the source signal for your test is 16:9, why are the test videos cropped? AFAIK, any analog machine can record any aspect ratio, it does not know what the proportions of the image should be, it just records the lines. If you feed widescreen into your VCR, and then play it as widescreen, it should look perfectly fine. Also, why 30p, not 60p? Also, I can see jitter during playback, I guess you don't employ a TBC?
This was recorded from an analog channel in my house that's tied to a DTV box, and yeah it's cropped. I just prefer it that way. In Analog video, you lose a lot of vertical resolution with black bars and I like to fill the screen, just my preference I guess. Also the samples were captured/deinterlaced at 59.94, but I believe the DTV box is spitting out 30fps since the channel is transmitted in 720p instead of 1080i. Then my video was rendered at 30fps, so it's all a jumble - best to just ignore the frame rate part of the test. Unless you're referring to the jitter on the scrolling text - that is my amateur code running on the raspberry pi causing it to jump like that :)
@@probnotstech I am not sure I am getting the reason for cropping. You've rendered a widescreen video for YT, so you could as well have recorded off a widescreen channel to the VCR and then play it back as widescreen. Or you could have used content from a 4:3 channel and crop only the black side bars that would be there already. Anyway, just nitpicking :) I don't want to ignore the frame rate part of the test, because it IS an important part of the test and it affects image quality. I expect analog video deinterlaced into 60p :) I was talking about minor line jitter, the left margin is not completely straight and vertical, the picture sort of shimmers. I suppose you do not employ any TBC or TBC-like device.
I didn't want to go and mess with the DTV box. Stretching the video to widescreen when played back from Beta (or VHS) would feel inaccurate to me since we didn't typically record anamorphically like that on those formats back when they were used. My first experience recording in anamorphic widescreen was MiniDV. With the frame rate, i record my videos in 30fps. I try to render 60fps when there's recording examples in the video, but sometimes I forget. Oh well. And yeah, no TBC on this example. It looks just as wobbly as it does on my CRT!
@@probnotstech I have a PAL Video8 camcorder that can do 16:9. Widescreen became commonplace in Europe since the late 1980s, first with satellite TV and then with PALPlus. I also have a professional handheld NTSC VHS camcorder from 1993 that can do 16:9. Just saying, but respecting your choice.
I wonder have you deinterlaced the video into 60p by converting each field into a complete frame? Since this is a static image, I think that if you treated the video as progressive, you would get higher vertical resolution with less moiré and line twitter.
Great video thanks for sharing the information! Greets from Marcel The Netherlands in Europe 👍🙂👍
I play stuff from my MacBook Pro onto my crt with that cheap HDMI2AV adapter and then when I play videos I use VLC player and play around with the aspect ratios on the app until one looks good on the crt. Usually stretching old tv like 90’s Simpsons into 16:9 forces the footage into 4:3 onto my crt.
JUST bought a CCD-V110 from goodwill today will absolutely try this
Oooo thats a big chonky boy (subbed btw)

Great video,just bought one of the Casio tv-21 its a a neat little tv,love these old portables I have a few my self,comparing the watchman with it I must say in favor of the tv-21 it’s much smaller and lighter so one of the advantages apart from the price...😊
That 8mm unit makes better video better than I expected.
Right? Some things look quite good on it. I think the soft picture on the outdoor scenes was the missing hood ring causing glare.
I built a battery pack for an RCA CC432 the other day. The DC input takes 9.6v, and NiMH battery packs produce that much. I cut a small hole in the casing, and soldered in a Tamiya connector to the old battery prongs. Now I can charge battery packs with USB and swap them out. The battery packs are attached to the back of the unit with velcro for swapping or recharging.
To my knowledge the CCD-V110 is one of the last Sony camcorders before they switched to the crappy SMD capacitors that are all bad by now. The follow-up model, the CCD-V200, is troublesome. I have replaced the cells inside dead battery packs in the past, but combining battery holders is a great idea, much more practical :)
Yeah, I won't even touch the camcorders from that era. Our family camcorder (an RCA Video8, possibly made by Sony around 1992) suffered the bad capacitor fate in the late 90s.
I am just working on a LiFePo4 based replacement battery pack for my panasonic NV-180. These cells work super well as a replacement for lead acid batteries. On my other camcorder (NV-M3) I am using a small 12V motorcycle battery on the back, even works with the original charger! :D
I did something similar to build a new battery pack for a Compaq Contura 4/25c laptop I got last year, original 90s era NiMH battery was pooched, so gutted it, re-used the internal wiring, used 10x "EBL" 2500mAh AA NiMH cells to create a "12v" pack, and it works perfect, and now is a bigger capacity than it originally was with smaller cells too... :)
The original battery looks like it would fit 2 18650 lithium ion battery's. I did this with an old RCA vhs-c camcorder and it worked perfect.
I considered lithium batteries, and may still try that for stuff in the future. For now, I just wanted to use what I have on hand for cheap.
Seeing modern pickups scurrying along the road on the Video 8 recording made me feel as if I was watching a VHS recording of an 80s sci-fi movie
I use lithium ion AA rechargeable batteries as they run at 1.5 volts.
Adoro il VIDEO8.bel video
oh well it would of been nice if i watched this before ruining my vhs player did find a scrap one to slavage a new head from
Please can you clean the VCR's before using ? There's a lot of dirt on the top. I've purchased a VCR on eBay a few days ago and the first thing I do is to clean it properly before using. I can understand this...
I really only clean them first if they're incredibly filthy (like "not coming in the house" filthy). Otherwise I like to test them out first, then clean them.
thanks for the tip on the screw to adjust the threading gear & motor. You recommended to back off slightly but in my case it got quieter by going as tight as possible.
the tape duration (remaining tape) is effectively obtained by revolutions speed of spools. and it's even capable of getting remaining time of any kind of tape duration, was a unique feature of early 90's models. philips also used this technique with the V2000. i worked on one of the same era, the HR-D550MS (europe model) and it got the same exact issue with the PSU, same dead zener diode. but in my case, most of the capacitors were missing when i got it. so the psu was whining but as capacitors were missing... i thought it was that :D the black streaking in your case are effectively not bad heads, but a shifted adjustement for a recording setting (deviation, or rec FM level for exemple) can cause an overmodulation and... black streaking. maybe there's a common setting for each speed.
My family back in the day had an early 2000s Panasonic 6 head S-VHS machine which was absolutely fantastic. Played commercial EP tapes (A Town Like Alice) fantastically.
can you link that coaxcable switch, that takes connections to the house
I had one when I was a kid
Hi available now please inform me sir
Good idea to always use a dimmer on these old lamps.
can you watch 16:9 content using this setup but stretch it wide enough using the remote so that it overscans to a 4:3 ratio? (clip the sides off the 16:9)
We had this RCA VCR for the majority part of the 90's, I remember the click noises it made throughout the modes. Awesome. The difference was the blue lines on the plastic ours had instead of the yellow ones this one has. Great players and recorders but one day it just died and never turned on ever again. 😢 Then we bought a DVD-VCR combo, it was just crap. 😂 not even half the quality of the RCA had. Great video.
That was a really nice vcr back in 1988 i was going into middle school in the fall of 1988. Im 48 now. Thanks for sharing this.
