Default Ferguson 3V22/Baird 8929 VCR no picture

Hi all

I was very lucky the other day to stumble across a 70s Piano Key VHS VCR and win it. I can't work out whether it's a Ferguson or a Baird as it's missing both of it's badges, front and back. Since getting it I've changed the belts and cleaned the heads

Upon testing it only plays back audio, no picture. The TV is just blank, not even a raster. Slightly tuning away will produce noise to either side of the screen, depending on which way I tune, which reacts to the video.

Flicking the switch on the back to any one of the 4 positions does nothing. I assume 'set up' are tuning bars, but I wouldn't be surprised if a VCR this old doesn't have them? I'm not sure.

I don't really have a clue of where to look first as I've very very little experience with VCRs, and especially VCRs of this age

Picture for further identification, if it helps

Thanks

Any video from the video out the pl509 socket if so maybe the e to e power supply or rf modulator

There's more of a response from the video out socket, but not much more. I've attached a photo of what the output looks like. This moves up the screen but I imagine it's a loss of V sync due to low signal conditions

Thanks

Badges? We don't need no stinkin' badges.
It was made in Japan by JVC.

Does it play back a pre recorded tapes OK?
The next logical move would be to eliminate the tuner by feeding a video input to the other PL259 which I think is marked "camera".

I think the person who had this before me agrees with you!

I think it's a HR 3330 rather than 3300? I've not found any definitive answers elsewhere.

Didn't think of feeding it a source, i'll try that now!

Thanks

Theres no output with an input to the PL259 either. So I'm assuming it'll be a tuner fault?

I also forgot to say it cannot play back pre recorded tapes, audio only, no picture

Thanks

Did you select the direct input with the camera switch on the front?

Well, it won't be a tuner fault. Have another look at the PL:259 video output. Inject a video in (or camera in) signal and see if you get an output. Also try an RF input if you can. It seems the fault is somewhere in the video switching circuit. An unusual fault, so it's a good idea to open out the circuit boards and carefully check for plugs disconnected, cracks or spillage. Does the vendor say it was working or was it sold as seen? That way you might be guided in the right direction.
Good luck!

I'll try that in a second, I'll have to figure out how to convert everything to get it to work

With an RF input I couldn't get it to tune into anything, but I get RF loop through with no problems at all, if that helps

Will have a check on the boards and all. It was sold as seen. There was no info at all

Thanks

Might even be a tarnished switch?

Possibly, I'll give them all a spray with cleaner and see if that makes any kind of difference

If I remember correctly you needed to put these machines into record mode to get E to E, otherwise you just got a blank screen.

Hi

Just tried flicking all switches with a tape inserted and loaded up and all possible combos but still no output but not sure if I ever put it into record mode? I'm assuming you don't mean pressing down play and record together though

Thanks

It was a quirk of these machines, I think just pressing the record key down by itself gave you E to E

What's E to E? Sorry if thats simple, I've not heard of it before. Pressing down the record key on it's own with a connection to the PL259 gives no picture output with camera selected, but with TV selected there's a hiss. Still no picture

Thanks

Ah now that makes sense! I actually remember reading that thread now I've seen it again, though it would've been some time ago.

Thanks for linking that and jogging my memory. I'm guessing this means there's a video output fault somewhere?

Thanks

It could be any number of things; component failure, missing voltage etc (good advice in post #9).

If you have access to a scope and a schematic, try feeding-in composite video and tracing the signal through. Ensure the power supply is healthy and outputting the correct rails. Compare and check signals and voltages referenced in the schematic around any processing IC's, switching circuits, board interconnects, etc, etc..

Unfortunately I've got no scope or schematics so have very little chance of fighting it so far if it's an electrical fault. As per post #9 I couldn't find anything that looked wrong so I'm assuming it's component based.

Maybe someone on here has a schematic they'd be willing to scan or has a link to one?

Thanks
