Thanks for the advice, but I think I'm finished.......

I do not have oscilloscope.

Three spring screws tightened and then a 3x turn back?

This I misunderstood, my English is not very good, I taught her in slaughterhouses in Ireland 30 years ago. :)))

Damned,

When a problem of snow image arises, I try to attach a CRO to the RF out of the head preamp board. Looking at the pattern showed by the oscilloscope you might be able to guess (or at least having a clue) wether you have a problem of the tape entrance / exit side or worn heads so the issue can be spotted. Also check for the head switching pulses to be correct. As a rule of thumb, when replacing hall sensors, I screw back the three screws until the end, with common success.

I have also realized that you have an audio issue (that annoying buzzing sound so typical from the C9s). Usually there are a couple ICs involved on this problem (check the technical section, it is described).

Hope you can fix that lovely but complicated machine.

Regards, Gabriel

Found these two solutions which may or may not help.

1. Check capacitor C38 on the RV7 board for failure.

2. Check for dry joints around transistor Q701.

Could also be dirty or clogged heads.

Now my second C9. ...

Next level after repair distorted elevator, two microswitches and replacing hall sensor.

Now head spins, (thanks to Kevin) but very poor-no picture.

When I rotating with the three screws with springs, picture a little (wery little) better.....

Tony:

It won't accept a tape as the loading arms are out. It's a safety thing.

Try moving the small switch just in front of the head drum.

It is a white rectangular box with a lever. If that is faulty it could be causing your current issues.

Damned:

Try the grounding check as Tony has suggested.

check the grounding of the video head, possibly you fail a shield ground.

I know that my English is very bad. I can not put a videotape leaves no load because the rollers are like there tape.

Here is a video to see if they understand best.

Hello Kevin and thanks

My plasmaTV is ok.

Could be interference between your LCD and the vcr.

I believe someone else here had a similar issue.

It doesn't look like drop outs or static.

Is the tape scratched (doesn't look like it's that but worth a look).

Try to put a video up of it's behaviour, your broken English is making it a bit hard to fully get what you are trying to explain.

I checked and it's so perfect the two that exist, the load and below the mechanics.

I got your message but for some reason can't send reply emails as we are travelling overseas in China.

Check the load solenoid winding as the fuse in it may have blown. Fixing you faulty loading operation will be a process of elimination as there are a number of actions involved.

Most likely the black plastic loading gear has broken and is spinning on its drive shaft.

It performs the dual role of loading the cassette then windin the tape around the video head drum.

Look at pal site Betamax page select videos then SLHF100 from the list and the select technical and look at the bottom of the list for instructions on how to repair the gear.

Good luck

not black plastic that speaks to me, but I think the problem is not going out there.

I will try to explain as best as possible, because my English is bad, I speak Spanish.

when you turn it on and hit the stanby no tape, the tape compartment is up, but the charge rolls are as if there was a tape inside. the tape compartment right, I take it out and put my tape manually load and switches guncionan perfectly well.

when I return to give the stanby and I again turn is when all the lights play, winding, rewinding, rec, pause light. then starts to rotate the spindle and the spindle motor, but not the collection roller tape. the solenoid does not act above nor below. then I give stanbay to stop and if I leave one minute so when I come back to give the stanbya engines are stopped.

I think it is an electrical or electronic problem, a tension that is not or something.

Thanks, Gabriel.

Now i'm waiting the belt kit, for the V-9600. At the moment i have rejuvenated the idler tyre.

I hope the mechanism, and electronic working properly.

At the finished restoring, i'm using this V-9600, with a Sony PCM-701ES.

Thanks.
