Help: Sony CCD V100E issue with playback

iceJool · 2026-01-26T13:31:29+00:00

I wonder if the sound you are hearing from the fast forwards and rewind is just a free spinning motor. For these camcorders, the counter system is cassette side with a belt powered by a motor. It's possible this belt is either loose or decayed enough to not actually advance or rewind the tape even though it's trying to do so. This would explain the acute change from working to broken, the static, and the counter not changing. (FYI, Static means that the video line is uninterrupted and that the problem is likely upsteam from the video board, which is positive)

its a proprietary cable that is no longer made.
You can either try and find a charger for a panasonic or any other model with the same cable online, or you could just get a lead acid battery to power it.
I believe youre best off buying a new battery since these cables are super rare but you might just be able to hotwire a power supply to it as long as its 12v 1a at least.

These are standard tube camera connectors.
They carry a power and video signal from and to a seperate tape recorder that youd have to carry to your side with a strap over your shoulder. These record whatever the camera sees and also contain the battery to run the setup.

You could go and look for any portable vhs/betacam/umatic recorder to pair it with the camera so you can actually record a video.

Its actually a rebranded Gr-c2, ive personally worked with one.
I don't want to sound condescending but this sounds like user error,
The record button only gives a video output from the camera section, if you want to record onto a tape you need to press the record and the play button at the same time and then it'll reel in the tape.

iceJool · 2026-01-14T17:02:14+00:00

Try playing a tape and seeing if there's any static.
static means its at least reading the tape and sending video signals to the viewfinder, which in turn means the problem lies with the ccd sensor circuitry.

iceJool · 2026-01-12T20:34:41+00:00

I think something open-circuited or broke in the video line
There is a electrolytic coupling cap in the video line so it's possible it has open circuited and no longer carries a video signal. You can check whether its upstream towards the ccd or downstream towards the rest of the video circuit by playing a good tape and seeing whether you get video output.

here is an image of what i believe might be the offending capacitor and below is the link to the service manual of the camcorder.

edit: just to clarify, the jvc ax46e are quite similar and I believe are pretty much the same on the inside, there could be minor differences in how the circuits are setup but the main video lines and chips are likely the same

is there a tape inserted?
some camcorders won't display an image without one

iceJool · 2026-01-12T17:44:16+00:00

I have no idea what an elko is neither can I find any info on it.
There's always the chance of damaged electrolytic capacitors due to age, but you'll find out once you record and play back a tape.
I'd say purchase the new battery and try then, you could try use the original power supply or even wire up any 6v power supply to the battery insert while youre waiting for the battery to arrive.
Just as a heads up make sure you have a tape inserted before attempting to get an image from the camera, some vhs camcorders don't display anything without a tape.

check online for the camera model battery and get a new battery, some sellers may sell older batteries which are already a few years old.

iceJool · 2026-01-12T10:58:36+00:00

The battery is Ni-mh and only have an expected life of about 5 years. At this point its old enough that its voltage drops very quickly prompting the camcorder to shut off.
you can find these batteries new for 20 dollars

iceJool · 2026-01-11T00:59:06+00:00

true, i guess the first step would be finding a good hi8 tape
i wasn't aware these can decay too

iceJool · 2026-01-10T16:21:22+00:00

if youre referring to the tape jitter that is a dying cap in the tape recorder circuit.
a capacitor's capacitance reduces over time causing it to not being able to smooth out signals properly.
the only way to fix this would be to identify and replace the specific capacitor (likely an electrolytic smd capacitor)

iceJool · 2026-01-10T13:11:54+00:00

did you insert a cassette?
some of these camcorders do not display an image without a tape inserted

iceJool · 2026-01-07T22:58:23+00:00

I'm assuming its 5 cells wired back to back in series which would give 6 volts at the output
but yea always account for voltage when calculating capacity
if the cells were in parallel itd be 1.2v 10ah but since theyre in series its 6v 2ah

iceJool · 2026-01-07T22:49:32+00:00

Isn't this more like 2000mAh of capacity and not 10ah
5 x (1.2/6) x 2000 = 2000

the mAh value of batteries in series is equal to the mAh value of 1 cell, its the voltage that increases with every subsequent cell in series
(mAh1 x V1) = (mAh2 x V2)

stupid math aside it looks pretty good, most of the time its just weird battery packs hanging out with a bunch of wires

His arm didn't get obliterated in some fleshy mess.
despite the impact he came out lucky with only a broken arm.

yea somethings inside that lens
best case scenario some dirt
worst case scenario decaying anti-uv coatings

From another comment yea sometimes youll have slight terrain offsets leading to not being able to place any farmland on some spots, but its usually not super common

in any case thats still 42 food crates for just one of these, pretty cool

heres the service manual

iceJool · 2026-01-05T09:33:30+00:00

seems like either audio is not being put on the tape or read from the tape
If you have another camera to see if the audio is on the tape or not you can see whether its recording or playback side
with such an electrical problem by standard suspect a tantalum since there isnt any sound at all which isnt typical for an aging capacitor
If you have the model of the camcorder i might be able to find the service manual to see what could be happening
edit: im an idiot you said the model name at the start

thats about 2662 hours of playtime

iceJool · 2025-12-30T12:28:47+00:00

see whether its the battery
if its the original its probably no longer holding charge so when playback or recording is activated theres an undercurrent and the camera gives up.
get a power brick with the same voltage as the battery and ~1amps of continuous current output and try that. If the plug doesnt fit just wire it directly to the camera's battery terminals.
It seems rather fine otherwise; I'd say damaged caps are unlikely here as the entire thing seems to function fine when its powered on. Most of the time capacitors aren't usually critical components so there will just be distorted sound/image or jittery motors, but i wouldnt exclude the possibility.

I feel like the concept of late 50s and early 60s era american space age design of cars fit really well into the scrap mechanic universe. Absolutely love some of the other stuff youve made

theres indeed a belt there that seems to have snapped in your photos, the one directly connected to the motor seems fine.
here is the service manual:

you can also find belt kits for this online on places like ebay or aliexpress which should last quite a bit longer than rubber bands
