Hi Leo,

Thanks for your response. The tape eject mechanism ceased to move forward - allowing the tape to eject.

Also, there is a constant banging noise when powered up. Both are probably mechanical and parts will be an issue to source, but I'm no engineer or Betamax specialist, so hard to gauge. Please let me know if more specific information is needed. Regards, James.

Hi James,

What seems to be the problem with the SL-HF950s?

Hello,

Is there anybody who could help with a Betamax repair? It's a Sony SL-HF950 Super Beta.

Any info would be greatly appreciated, thanks.

Hi Kevin.

Thanks very much for the information. If the pot isn't at fault are those replacement parts obtainable?

Thanks again

Rich.

That issue is common to the 9300. There is a potentiometer that needs slightly adjusting on the bottom board.

If that does not solve the issue an IC could also be the problem but I would suspect the adjustment pot.

Adjust AFC(VR - 214). If that fails, replace Q204(IC, CX -150) and surrounding electrolytic capacitors. AFC may need to be adjusted after these components have been replaced.

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

Just another note to my last message...

I've just been playing with this vcr and when I switch from test signal switch on to off the colour comes back intermittently. As soon as I adjust the tracking or put it in pause the colour goes off again back to a mainly black and white picture with the rainbow effect. I'm using the BNC output.

I wish I could post pictures on here to illustrate the problem 😤

Thanks.

Rich.

Hi all.

I have just acquired a Sanyo VTC 9300PN. I've replaced the belts and forward idler and given it a good clean. The problem I have with it is on playback. The picture is mainly black and white with a kind of rainbow effect of colour appearing on the picture. It's the same when connected with the aerial lead and with the BNC connector. I have not tried recording on it yet.

Do any of you guys know what the problem could be please?

Many thanks.

Rich.

hullo, all..

please forgive me if this is a FAQ -- i am new to betamax. (though i am old enough to have had one in my home as a kid..)

i am an IT guy and have been asked to convert (to .mp4) a box of old Betamax tapes in someone's storage, for a non-profit organization, which were recorded in the 90's.

so i am in the market for some kind of betamax player. i see from perusing ebay, craigslist, betamaxcollectors.com, and palsite.com that -- as may be expected -- many of these machines are by now in great need of overhauling before using. and that if they ARE running, they get a pretty penny.

my question:

these tapes are old enough that i am sure they have degraded over the years. so if they play at all, they will likely have tracking problems and data loss.

therefore, of all the models available, would you folks either have recommendations for..

a) specific models i should try to go for, which would be best able to deal with old tapes and produce the best picture?

OR

b) if not a specific model, then at least specific features (number of heads, auto-tracking, hi-fi, etc.) which would be best likely to handle these old tapes and produce a good picture?

AND

c) any other considerations i should know about?

thank you!

The Yoshio Sawaji report is correct for EIAJ recorders, the CCIR standrad for 1/2" video recorders is quite different, for starters the speed is much slower than a EIAJ machine. EIAJ is 19.05cm/s, CCIR is 16.32cm/s.

The only thing in common between EIAJ and CCIR machines in the tape width, they are not compatible otherwise. You cannot play a CCIR tape on a Sony AV3650 nor could you play a EIAJ tape on a Sony AV-3670. To suggest otherwise would be at least unhelpful.

I own, and maintain, a vast number of Sony, Panasonic, National and Shibaden 1/2" machines in both formats. Even have a number of the Panasonic 1/2" cartridge machines.

Hi,

This may be beside the point, but I rather think the acronym EIAJ refers to a VTR format (among many other things). They are classified as EIAJ-1, EIAJ-2 and 'pre-EIAJ', all of which use ˝-inch tape, wound on 5 or 7 inch open reels. There are also EIAJ cartridge VCRs.

EIAJ-1 is a monochrome version, compliant with either NTSC(525/60) or CCIR(625/50) video signal format (I have a few CCIR decks). EIAJ-2 is a color version, compliant with either NTSC or CCIR/PAL signals. The so-called 'pre-EIAJ' machines are more or less proprietary, evolutionary formats, developed by various companies prior to about 1970.

European EIAJ machines were marketed at least under these brands: Bang&Olufsen, Grundig, Gyyr, Hitachi, IVC, JVC, National/Panasonic, Philips, Sanyo, Shibaden and Sony.

According to the document below, it seems that half-inch open reel VTRs should be called EIAJ, before anything else:

“EIAJ Standards for 1/2-in Videotape Recorders” Journal of the SMPTE. v.79, December 1970, submitted by Yoshio Sawaji.

Anyway, there are still EIAJ video footages in Europe that nobody has seen in 50 years. That is why we should have a chatpage to discuss how to make them viewable once more.

Leo has a good idea.

Please add a chat site Video8/Hi-8

Leo, technically speaking EIAJ ( Electronic Industries Association of Japan) are NTSC recorders. The PAL version is known as CCIR (Consultative Committee on International Radio) the committee who developed what would later become PAL.

Dear Sirs,

Why not set up chat pages for VHS/S-VHS, Video8/Hi-8, Philips/Grundig VCRs and EIAJ VTRs here at PALsite?

This would then be the primary European VTR/VCR net forum. I can also post here technical descriptions of

various technologies used in video recorders.

Thanks

Here is perhaps the best Low Band player in the world (PAL). Also with a Y / C output of course. If and when the others do not get played back your tapes, we can. Comments are welcome.

Mr Heap.:

It sounds/looks like a Betacam or umatic vcr.

Please post this on the appropriate board.

(Look to the list on the top left of this page).

The Sony VO-5850P has developed a tape transport fault so that when inserting a cassette into the recorder the tape is at first stretched out round the record head in the normal way. The tape then almost immediately goes slack. The recorder does not go into the standby mode. Play, record, search, fast forward, fast rewind do not work. The cassette cannot be ejected.

I am advised by a video repair engineer that this is due to the failure of a component on the circuit board that controls the tape transport and that as it is impossible to identify the component that has failed the best remedy is to replace the entire circuit board. However the Sony VO-5800 /5850 series are obsolete in the UK and circuit board spares are difficult to find. Advice welcome.
