Hi folks, I wonder if anyone can help? I've recently purchased an untested C6 from ebay. I got lucky in that it powers up, laces perfectly and all functions are "working" only the picture is terrible. The picture is visible but there's hunting / surging, a haze of static and a continual strip at the bottom of the image that I can't track out. I haven't started pulling it apart yet other than to clean the heads. I am going to assume that at least some of the caps need replacing. I wonder if anyone has a list of the types, ratings etc.? I see this was done a few years ago here http://www.r11txe.co.uk/uploaded/c6-ss9-caplist.xls but the webpage is now down. I'm also going to try to find a replacement belt set. Thank you in advance.

Hi Kev, Thankyou for the reply. Had a closer look and it seems to be the wheel with the tyre that's the problem, Fast forward and forward search it seems to flip over nice and strong but on rewind and reverse picture its lazy and doesnt seem to push as strongly against the rewind spool then clicks off back to the middle after around 3 seconds. Any ideas please?....

In regards to your current issues with the C20 , it's down to either the heads are dirty,worn or damaged as that would cause static and no picture.

Also check the soldered part of the BNC OUTPUT as those types of sockets to the boards on the Sony's are vulnerable to knocks resulting in the solder getting cracked.

As you have static though i would suspect the first three things to check.

If you have never cleaned a video's heads then tread carefully as they are VERY FRAGILE.

What i would suggest is put tape in your know to be good quality and let that play for a time, even FF and REW it, as it's always laced around the head drum.

See if things improve.

Good luck..................Kevin

Hi everyone.

I have a Sony C20 that is in really nice condition but whatever tape I try to play it is just snowy / static. If I fast forward or rewind then I do see some faint scrolling diagonal lines. I am pretty sure that the tapes do have content on them so I am assuming the unit itself is faulty.

I am connecting to the composite input on my CRT tv using the BNC video output on the back of the Betamax with a BNC to RCA adapter. I assuming that this should give me an output but i am not sure if I need to use the RF output instead.

Do these particular symptoms suggest an area I should be focusing on to try and repair?

Hopefully someone can help

Hi Matt:

Good to see you here.

You say the idler (center pulley) is playing up.It sounds to me like it's a bit stiff on the shaft for it not too move like you state.

As the geared top part does the search and PLAY modes and the rubber lower the FF,REW and take up after stop.

Also on the very early VTC 5000 's (with the flip out right side end sensor and one piece clutch).Some of these center pulleys were shiny for the contact part of the rubber idler tyre. Sanyo soon realized that mistake and all other plastic friction areas were grooved.

The one piece clutch's (which could be tricky to set up and therefore make the back tension at times a bit higher than required) were also exchanged after time for the more reliable and consistent two piece ones fitted to their Beta's right up until the end of production.

As for your issue i would see if the center pulley is a bit stiff or not move freely and then make sure the others mechanicals are also free to move.

Also a video of said action is a big help too..

Hi All, New to this chatting thing. I notice Kevin Lambert is on here who kindly sorted a few of my machines over the years. The Idler is now playing up on my VTC5000 does anyone know where I can get one from to fit myself. The belt seems ok so I am guessing its faulty idler it doesnt flip to the left upon rewind but does on picture search reverse for about 3 seconds then flips to centre and just stops. Any help would be appreciated. Thanks Matt

Check out the SLC9 page under technical for Betamax models under the heading "irregular rewind/review."

It is likely to be due to increased friction due to wear on the upper drum.

You can use an ink rubber to scruff up the surface of the upper drum to cure this issue but take care to move the heads out of the way at the same time.

I have also used cleaning pads we call JEX pads (CLEANING SUPPLIES) here to do the same job.

I have 2 SL-F1 that still work very well except for one little problem:

When I rewind a tape i often notice an annoying phenomenon as if the tape sticks and jumps off producing a series of tears: "strap" - "strap" - "strap" .... I have noticed that some brands of tape they do it more and others less, for example some Sony do it less while the Dupont do it a lot. It resembles the Stiking phenomenon.

In some cases the ribbon transport stops completely.

What can be done?

Hello i need a help please.

C9 does not eat the cassette.

The microswitches are OK.

Display and tunes led not light on. When turned C9 on, the mechanica moves and the heads second rotate. Power led and frame lighting.

What to focus on, please?

When the DC Dc converter is bad, it only just doesn't go on display?...others should work, yes?

Thank you wery much.

Does your C7 eject the tape?

I'd recommend changing all the belts as they are likely 40 years old. New belts, with their 'youthful' firmness provide more torque for the aging mechanism and will certainly help waken the machine up, making it operate better!

I have a question about the Sony C6:

The clock display is probably about 60% brightness of what it should be. Is there anything I can do to restore the display to full illuminance?

Hi! I am new to this site.

I just bought a SL-3000, but it came without psu. Does anybody know the pin out of the 4 pin DC connector which is on the right hand of the recorder?
