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 '77 |

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

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 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 '77 |

Re: Ferguson 3V22/Baird 8929 VCR no picture
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 '77 Last edited by 19Seventy7; 9th Oct 2021 at 7:52 pm. |

Re: Ferguson 3V22/Baird 8929 VCR no picture
Did you select the direct input with the camera switch on the front?

Re: Ferguson 3V22/Baird 8929 VCR no picture
I tried with both, camera and TV, neither had any effect unfortunately

Re: Ferguson 3V22/Baird 8929 VCR no picture
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! |

Re: Ferguson 3V22/Baird 8929 VCR no picture
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 '77 |

Re: Ferguson 3V22/Baird 8929 VCR no picture
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

Re: Ferguson 3V22/Baird 8929 VCR no picture
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 '77 |

Re: Ferguson 3V22/Baird 8929 VCR no picture
It was a quirk of these machines, I think just pressing the record key down by itself gave you E to E

Re: Ferguson 3V22/Baird 8929 VCR no picture
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

Re: Ferguson 3V22/Baird 8929 VCR no picture
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 '77 |

Re: Ferguson 3V22/Baird 8929 VCR no picture
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..

Re: Ferguson 3V22/Baird 8929 VCR no picture
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 '77 |
