hows one get this hooked up to a display monitor?
my atempes have nothing showing scope shows i have signal
tried with a projector through the rca jacks and bnc on a lcd monitor tv i have that has rca svideo and bnc jacks on it
help?
dr.ido 05-12-2014, 10:21 AM Video output from these is composite video on a "UHF" jack (that same jack commonly used for the antenna on CB radios) - it's also present on the 8 pin connector, but those cables are difficult to find. Easiest way out is probably a UHF -> BNC adapter and then a BNC -> RCA adapter.
If you already have the adapter/cable I suggest you try an old CRT TV. The processing necessary in LCD sets (and most projectors) probably won't lock onto a signal that is that unstable.
If the LCD monitor you're describing is one of those Samsung/Supervision commercial/surveillance monitors (the first that comes to mind with BNC and S-video inputs) I am almost certain this will be a problem. I gave up using these for test monitors as they were too fussy about what signals they would accept. They would not display stuff that worked on every other LCD set in the shop.
I've found many LCDs have trouble with the signal from a VHS deck if the tape (or deck) is in less than perfect condition or the tracking is off. The unstable signal cause the picture to drop out. The signal from a skip field type EIAJ VTR will probably be even less stable.
Old CRT TVs/monitors are far more forgiving as they don't need to process the signal. The picture may roll and breakup as the signal degrades, but you'll see something other than "NO SIGNAL".
If you need to capture these old tapes to a PC card or DVD recorder ideally you'll want a timebase corrector to stabilise the signal first.
ok
makes sens wasnt sure
bashing my head trying to find a crt i relized the junk pile at the hacker space has something... witch i hooked up and got this then it stoped displaying anything and the high pitch noise u get off old monitors went away as well so i will asume that just commited suicide

it died shortly after i shot the pic
dr.ido 05-12-2014, 08:45 PM Those flybacks in those monitors often fail, but they usually squeal when that happens. If the monitor is completely dead (no squeal, no LED) check the power switch, also a common failure point on that model.
The signal you've got there is too far gone for and LCD set to lock onto. The deck probably needs some work.
Shouldn't be too hard to hunt down a CRT TV with AV inputs if that monitor is unrepairable. Just got to get to one on the curb before the copper scrappers.
being its a hacker space someone showed up with a replacement monitor for me and irconicaly the same make and model of monitor and this tape is about seting a crt up actualy witch is kinda funny
i dont get any audio off the machean just static

not in the video if i put it to pause it works like it should
anyone know where i can find a manual?
dr.ido 05-13-2014, 02:32 PM The lack of audio and the unstable picture could be related. On VHS the control track is recorded/played by the same head as the linear audio track. A dirty audio head or other faults around the audio head will cause tracking problems.
Though if the that tape was recorded from what was originally a filmstrip there may never have been any audio. Do you have any other tapes?
when i turn the power on the audio needle goes nuts then sits at the bottom
yes a box of tapes
Electronic M 05-13-2014, 04:43 PM One thing to be aware of with tapes that old is that some develop an issue where the playing surface of the tape becomes somewhat sticky and the tape will have so much friction with the head drum/tape path that it will slow the mechanism down below designed speed or outright stop it...When this happens the tape needs to be cleaned in order to be playable again.
Also it can be helpful to adjust the tracking and skew controls when it is that close to working.
Interesting content on that tape. Are you going to transfer it to a modern format and make it available?
I also have some EIAJ video tape machines(and a whopping 2 tapes) so if you get sick of having that box of tapes I'd be happy take them off your hands...Might even be able to transfer the video if my machines wake up well from a 2+ year nap.

I second this... that takeup reel doesn't seem to be running too smoothly (seems to be lurching?), while the other one is fine. At the very least it'll play havoc with the tape tension.
i want to digitze the tapes witch is why i bought it
when i turn the machean on with nothing on it theres lots of noise that then slowly peeters out
dr.ido 05-13-2014, 11:47 PM An experiment that may help narrow things down - Try recording something on some "new" tape. Spool some tape from a blank VHS tape onto an empty reel. If you don't have any empty reels splice together a continous loop.
If the transport runs smoothly with the "new" tape your old tapes are binding. There are various ways to clean/treat the tape prior to playing.
Being a B&W machine it may not play nice with color video (even if it is working properly) - I'd use the Y signal (green jack) from a DVD player (just be sure its set to NTSC/480i).

99% rubbing alchohal recomended for cleaning the tape?

Not cleaning actually. What these tapes need is baking: the problem <ith EIAJ tapes has been found a long time ago to be sticky shed syndrome. The urethane binder loses its bonds which are replaced by water molecules, softening it enough to shed and stick on the transport with a horrible squealing noise.
If your tapes do not squeal, don't bother. If they do, you can "bake" them to 55°C for the time it takes to remove the water (it can be a day or two for a 1/2" tape), after which it is playable for a few weeks, and then progressively reverts to its shedding condition, but not worse than it was before. A tape can be baked several times, so put the tape back into storage when you have made a copy, for future use. There are several ways to "bake" a tape, and a kitchen oven is most definitely not one of them, it cannot regulate at such a low temperature and is perfectly able to melt the plastic, tape and reel alike. You can use a food dehydrator, or a laboratory oven, or even a cardboard box, a hairdryer and an industrial thermostat - which is what I do and it works well.
BTW the meter doing strange things at power-up is very common for machines of this age, it doesn't imply that there is a problem. Sorry, I can't see the needle on your video.

I'd strongly advise against doing that. Splicing a video tape is a pretty sure way to kill the heads of an EIAJ recorder. Also, VHS tape is really fragile for an EIAJ transport which has much more tape tension than a VHS transport.

We have some shedding Reel to Reel tapes. What I've been doing post-baking is sealing them in heavy-duty freezer bags with a pouch of desiccant. Keeping the moisture out as much as possible is preferable to re-baking.
Silica gel cat litter is cheap and works great for this purpose - or you can re-use those little pouches you sometimes get in things you buy, but be sure to bake them too if they have sat around a while or they'll be saturated with moisture already and won't do any good.
Just be sure to make a small cloth/paper towel pouch or a smaller plastic bag in which you've pricked a bunch of holes with a pin so the crystals don't get all over your tape. Anything vapour permeable but not too porous is fine.

I've run VHS tape on EIAJ decks before (though rather than splicing I just drilled holes in the VHS reels so they would go on the EIAJ deck), and it worked okay, though VHS tape will eventually stretch and become useless after a few plays.
I'd do some reading on labguy's world (a website) he seems to be the guru on EIAJ, and IIRC he addresses the tape degradation issue...Somewhere.
talking and to a friend and found out he used to service vtr's 20 years ago owns his own video production company that rents gear says i need to clean my heads from what i showed him

You probably need to clean the whole transport on such an old machine. Be aware that the video heads are very fragile though, and that if you don't do it the right way they will snap right off! In particular, don't clean them while spinning (important!), wipe the heads horizontally, never vertically!, and don't use q-tips! and don't use paper towels either, they tend to shed on the heads and sometimes the pressure of your finger can be
enough to break them if you are not extra careful. There are specific flat-shaped chamois tips made specifically to clean the video heads without applying pressure on them, they can be a good investment.
Check this page (http://www.labguysworld.com/VTR_FAQ_005.htm) for a description of the procedure.
It may be a good idea to ask your friend to show you how to do it the first time, if he's good he will save time and avoid nasty problems. While you're at it you can also ask him if he doesn't have a service manual by any chance ;)

The only description I've found on labguy's site is a video by someone else that gives dangerous advice (spraying silicone on video tape? NO WAY!!!). A common source of good advice on SSS is Richard Hess's site. There is also a good source there (http://www.wendycarlos.com/bake%20a%20tape/baketape.html), using a food dehydrator. The way to do it with a hairdryer and a cardboard box is explained there (http://www.josephson.com/bake_tape.html).

all the manuals got tossed when shaw bought out videon and he worked on sony's
pulled it outa the case to look inside some signs of humidy damage
http://youtu.be/3tM1lg89QIo aka lots of dirty contacts
o i finaly got some audio to come through
well this is a giant leep
havent done much other then run it

Yes, much, MUCH better :tresbon: Looks like humidity played tricks on the contacts and operating the old things is progressivelycleaning them up and remobilizing old hardened lubricants. You certainly can help with Deoxit and the proper asortment of q-tips, non-plush wipes and so on. The old belts look good, which is a piece of luck. The motor doesn't look so good though, but as long as it works and doesn't make strange noises I'd leave it alone.
As regards the problems with the monitor, the signal looks good except for those oblique bars appearing from time to time, which might be caused by a parasitic video signal (make sure nothing else is hooked to your monitor and VTR while playing the tape). The sync is not very stable but appear healthy. The vertical sync losses might be caused by the monitor (some are very sensitive to the fairly poor sync level and stability which are normal for an EIAJ deck), adjusting the vertical stability adjustment could help too. But they don't seem to caused by drop outs, as is usual in this format. Anyway the tape looks very clean, especially for an EIAJ tape.

definatly got sticky tapes part of my problem
