Mark, I have a PSU for the SL-3000. Not sure what the pinout is though.

Zane303,

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?

Zane303;

Sitting for that long it's more than likely a belt or rubber idler slipping.These models are not only very heavy but have numerous belt's too.If they are NOT stretched (like soft elastic)or hard and cracked/split they can be refreshed with 120 grit paper and also a soak with washing up liquid helps too.Keep isopropyl alcohol away from any rubber though as it will dry it out.

I would also check the electrolytic caps in the PSU too as when they go high ESR they take out other components which can be a pain for some to source.

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

Hi , i have a Sony SL-C7EC that has not been used for 15 years . When i turn it on everything works fine but when i put a tape in it starts doing a humming noise ( like a tape rewind noise ) . this noise noise fluctuates from high pitch gradually to low pitch . the tape does not need to be re-winded and i cannot play the tape . any idea what this is ?

Success!

You were right, Kevin. It was that .33uf 25v blue Sanyo capacitor that was causing the tracking centering problem. I replaced it with a .33 35v tantalum capacitor and it's working great now. Also the PSU caps arrived so I replaced all of them too.

One thing I noticed though was on the video board, 1 of the 1000uf 10v electrolytics was leaking onto the board and traces. Removed, board cleaned, traces repaired and new cap installed. All working great (touch wood) I'm going to leave it on test for the day just to make sure all is ok. All that needs to be replaced now is the front button membrane thing, but I doubt they're available now. Hey-ho.

Thanks Kevin!

Thank you Kevin. That's most helpful! I'm waiting for some replacement electrolytic capacitors to arrive for the PSU, so whilst I'm fitting those I'll mark the pot in its original position and give it a tweak. I'll change the blue Sanyo cap whilst I'm there too. I'll report back once I've had a proper look at it.

Many thanks again!

Dickie:

I've just had a look and the Adj pot you are after is labelled 'SUB TRACK' and is the first in a row of 4 at the top of the servo board to the left.It's level with the top board red screw you have to remove (one of three) to pivot up that board.Make sure when you try adjusting this you put the vcr's outer tracking control to the center.If it still does'nt eliminate all off tracking noise.You may have tape guide alignment issues.There is also a light blue Sanyo made cap on that board (near those 4 pot's).On some VTC 5000 's and 5150's these have gone bad causing non responsive tracking adjustment issues. Not seen that on any 6500's yet though.

Thanks, Kevin!

I'll take a look at those pots and try to find out which one is the tracking centering pot.

Thank you again.

Dickie:

The internal 'tracking control' pot is located on the board that stands on it's edge to the left.

It's one of 4 controls at the top.You can adjust it from either side.

Always mark it's original position.

It's odd that it affects all recordings unless someone has 'had a fiddle'.

Would anyone know where the tracking centering pot is located in a Sanyo vtc-6500 please?

I got the vcr yesterday and after the usual replacement of rubber parts to get it going again I noticed that the tracking knob has to be turned all the way to the left to get it to play all tapes without interference. It's the same on its own recordings. The a/ctrl head hasn't been messed with so I'm sure it's the tracking centering pot that needs adjustment.

Thanks

Regarding your issues with the Sanyo VTC M10:

The info regarding this area is limited but first i would check all caps in the PSU.

On the SY1 board. IC3002 (LM6402A) is responsible for the start up of the Head motor,this also links to B3005 (11R 10K) and a diode (D3076) that links to that motor. Check those and also the rudimentary cracks and dry joints to those (and other) areas on the boards.

Hi, Hoping someone can help me with this problem. I have a Sanyo VTC-M10 where the head drum motor does not spin up when you insert a tape. Voltage on the brown connector from the SY1 board CN4(pin4) to the head drum motor reads 6v when idle then increases to 7v when a tape is inserted, if I supply 12V to the brown wire connection the motor starts to spin the heads and you can start to see an image. Does this line suppose to supply 12v after a tape is inserted and if so does anyone know where I could start to look for worn components.

Cheers,

Steve

Ok, so not a PAL vcr but I've recently come into possession of an NTSC Sanyo VCR7200 Beta hi-fi vcr which has a colour output problem.

The output is in black and white but very often a vertical rainbow effect of colour stripes come up on the screen, often in pause and picture search modes. The TV's I've connected to the vcr are capable of displaying NTSC signals, so it's not a TV problem.

Is there a trimmer capacitor or some sort of potentiometer on the video board that might cause this? I can't seem to find out any 'usual suspect' problems online for this model like we have in the technical section on here.

Thanks in advance 😌

Apologies for all the typos in the previous message. I was typing fast because of the excitement of finding a Betamax fan community!

I have a Sony SL-C9, the very first VCR I bought in 1982. It is an amazing machine and far too sophisticated for its time or even now. I made my first student film in 1984 on the SL-C9 by hooking up a video camera to the front socket. I am now a professional documentary maker. With the advent new digital techonolgy, the Betamax recorder got little use, but I was so fond of it, I decided to keep it. It's been sitting in storgae for nearly 30 years. Now I need it to solve a mystery about a 1985 Channel 4 documentary which I recorded off air in 1985. But have hit an obstacle. The tape loaded, and nothing happened on pressing play. Nothing happend on pressing eject. I mamaged to finally get the tape ejected, sadly with a litle force. No damage to the tape. But the de lace and eject mechanism is stuck. On pressong eject, I hear some de lacing noise and then a rattle, that sounds like gears not engaging properly. The fault is mmechanical. Broken gears? Belts not working properly. I don't dare touch anything.

I know I can buy a working SL-C9 on eBay, but am fascinated by how we can get this one working.

Any tips? If you can help you will contribute to solving a historic puzzle!

Thank you
