Bars in video

[pentium]

the Sony CCD-F77 makes a good mid-range stereo 8mm camcorder which is why whe my first one died I promptly got another one. (that and also the abtteries and accessories are compatible with my other handycam and my CCD-V5000)
This replacement works very well except that I'm getting bars in the picture.
So I troubleshooted:


To translate...

Video from:
-CCD to Viewfinder: OK
-CCD to Video Output: OK
-Tape to Video Output*: OK
-Video Input to Viewfinder: OK
-Video Input to Tape**: OK
-CCD to Tape: BAD

Pictures: What you see if you record anything from the internal CCD to a tape.

Okay, so something between the CCD and the tape recorder is wonky but what could there be? It's something so specific that it does not affect the video output as well as does not affect the playback of a previously recorded tape. (In other words, any other part of the camera)


*A test pattern was recorded to a blank tape on another camcorder then played back on my F77
**A test pattern was fed into the camera and recorded to a tape, then played back in another camera.

Re: Bars in video

bad cord? that looks like it might be static interference caused by bad shielding.

Re: Bars in video

just look at the boards,

a very common problem with all old camcorders - specially sony is loads of leaking surface-mount capacitors.

they are a bitch to replace usually because they are all bunched up together.

Yea. and Smell. Eject the tape and take a sniff in there. ROTTEN fish.

Re: Bars in video

Sorry. My nose is not tuned to the smell of what a failing cap does smell like.
Can anyone at least give me a general idea where to start looking? At any given time the CCD has a hlaf dozen wires coming off it.

Re: Bars in video

or cat piss.

what if a cat actually peed on his?

wait- that still results in a trashed camcorder!

Re: Bars in video

All I can smell are electronics and the crisp smell of PCBs that is evident on NOS computer hardware.
I honest'y do not know what rotten fish smells like.

Re: Bars in video

Does the camera perform same when you warm it up/cool it, or when it runs for a while.

Does it show the same lines when outside (indoor might be a fluorescent lamp interference, but I doubt that)

It's less evident in very low light conditions but in normal light conditions you can see it and in bright conditions it's very obvious.
No, the problem is instantaneous. It does not occur or go away after a period of time.

Re: Bars in video

If I at least open it up can I get a general idea where to look?

Re: Bars in video

all the ccd-f series had bad surface mount lytics.
i recapped lots of these units when they were fairly new.
they are not wine.they just get worse with time.
you have lots of work on your hands or a pretty rifle target.

Re: Bars in video

Great. Bd surface mounts. I'm sure though I can get that cured somehow.
Was the CCD-V series also another line with abd lytics? I got a V5000 here that has the same symptoms but can't record video worht a damn (it's garbled).

EDIT: "Yes" is the answer.

Re: Bars in video

Sony had produced bad CCD sensors from 2004 to 2006 era. I had to replace one for my friend of friend's. These IC is out of production by now.

Many major makers bought Sony CCD sensors in that time-frame. So this is not isolated to Sony's.

It usually is totally white out after few minutes of use or permanently black, streaking then totally blurry. These are the symptoms for bad CCD. The first camera with funny pink streaks is not this symptom. Second camera you mentioned later is probably this if this is in that time-frame.

Re: Bars in video

The V5000 is from the very early 90's so it's almost a full 15 years before the issue with the CCDs would occur.

Re: Bars in video

I also got a V5000. Can't smell anything when opening the tape deck. All functions are fine, but when I press the Record button, everything is garbled. It also takes some seconds to warm up before it is displaying something in the viewfinder.

I'll try replacing the caps. Hopefully it works again after that. It's a very nice device with a kind of futuristic look. A shame to throw it away.
