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.

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.

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?

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.

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).

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.
