Black lines in picture. No pictures in these lines at all

Hello,

Been trying to find info on this model for quite some time, but nobody seems to be able to.

This is a Sony DHR-1000VC. It (used to) play(s) DV and MiniDV tapes.

This is the mechanics of it

And this is the picture it gives me now for quite some time.

I found more of those problems over the net, and these appear to be gray lines. or lines in which there still is somewhat picture to be seen.

My device shows steady black lines, and in between the lines the picture is crispy clear.

Also sound hardly does a thing.

Below also a video of the issue:

Now,

Would i be searching this in a defective video head (since i've been cleaning this a gazillion times. Sometimes there's no picture when using an older tape. After cleaning, i get back to this picture)

Or should i have to look in a malfunctioning video board?

If someone can point me in the right direction, would be a great help :-)

Answer this question I have this problem too

Is this a good question?

Hi, Just wondering. Do the tapes record this way or are you replaying old pre recorded tapes.

Have you tried removing the tape head flex cable from where it is inserted into the motherboard and then re- inserting it to see if it improves. Got caught out once on a VCR where the 'head' cable had been pushed into the connector too far and some of the connections weren't making because of the insulation on the cable. Just a thought

These are tapes that have been recorded before. Tapes i know are good.

Head cable is no issue here :-)

Thanks for thinking along !

@bungieke does not look like a tape head issue. The lines are to thick and to symmetric. I found that with a bad tape head you get plenty of thin lines but not as symmetric as yours. I'd be taking a closer look at the JC13 board. That is the board that is amongst many other things, responsible for the DV in/out as well as the audio core. The JC13 is printed on the corner of the board. Take a close look at the caps on those boards. check for domed or leaking caps. Post some images of what you find with your question. That way we can see what you see.

Thanks very much for this info!

i'll check those boards in the weekend. It's my own machine, and it has this issue for a few years. Haven't used or worked on it for all those years, but i need it again now.

Will check for leaky capacitors.

Did tv, VCR, camera repairs before, just wanted to know for sure where to look in this particular case :-)

Sorry for the late answer. Bit strange how i have to choose "add your answer" in order to upload a picture aswell. Then it says i'm answering my own question, but i see no other option to upload a picture

Only see 5 capacitors on this JC13 board. Nothing leaky to see there. Since i don't know any values to measure on those with oscilliscope, I'll replace all 3 of them..

Could it also be one of those capacitors on this lower board?

Replacing caps on the JC13 board doesn't solve the problem :-(
