I should think it was diagnosed because they had a duplicate spare card locally to hand!

Possibly the system indicated which part had failed, or they opened it up and the duff component was the only one without any lights on


Smoke's also a good general indicator.

Magic smoke?

That, and big black stains where there used to be a component on a board.

Thinking about that Midlands Today breakdown, isn't that what Emergency Cut was invented for?
Write that down in your copybook now.

In the days of analogue, in our large studio centre, we simply had no standby or emergency cutting facility or provision. It was simply unheard of.

Only during and after the transition to 'digital' were these facilities designed in.

Makes you think for a moment doesn't it?

It's not quite a "new fangled digits" concept though - the 1976 vintage BBC Mk4 CMCR scanners had such a facility according to a 1977 article (section 5.1.2 on p12) which mentions it casually in passing rather than as a significant innovation. At that time most of their studios were still using knob-per-channel vision mixers.

Every BBC large production studio with BBC vision mixers
Had emergency cut and that sort of continued with GVG 1600
But then seemed to go away ..... and thus did not get "digitised"
Also as the E cut used the preview matrix but the matrix got subsumed
into the vision mixer /multi viewers so there was nothing to use as E cut,

When there was common equipment in all BBC regions allocating spares
Was an artform and a bit political but generally each station had its own plus one extra in Manchester Birmingham and Bristol

And IP facilities often have an SDI baseband cut bus to fall back on.
Everything is relative!

BBC regional culture in the 70s and 80s seemed to be to fall back to network when in trouble. I can remember South Today regularly (couple of times a monrh) falling off the air, or not appearing at all in the 70s

The old studios (not BBC) where I used to work (built 1993-1994) had a GVG250 desk, and a small Emergency Cut Bus with a panel that could put that bus Live to air. I remember having to use it once.

The Mailbox will have jumped up a place in the queue for a gallery refresh, following that mixer failure.

Impressive to have diagnosed the faulty card so quickly. Does the Mailbox have a pres gallery?

Yes, but I don't think that was used. ISTR it reported on twitter at the time that someone ran up from the BSC downstairs to swap out the offending card and bodge the vision mixer for 3 months more use until it was changed.

No danger of an upgrade but the new VM (which was brought into service 3 months after that crash) is HD capable, I assume because SD kit is just difficult to buy now!

Is what they replaced the earlier GVG mixer with

Here's a breakdown from the local election of 2006 were BBC One loses pictures just before 3 am


On further research, I found out it was a power failure in their studios and around part of the Westminister area at the time via Nick Robinsons Newslog at the time of the election: https://www.bbc.co.uk/blogs/nickrobinson/2006/05/lights_out.html

BBC One handed over to BBC News 24 just after 3am and didn't return till 4am when the problems were sorted.
That's TV and Local Television Ltd are the Carlton and Granada of local tv

This was fantastic, and very forgotten now - it was a fairly unremarkable local election year where not much notably happened so it got less attention than had it occurred during a General or major referendum. When coverage resumed they’d moved to a pub in London with results being announced on bits of paper being passed to the presenters, which seemed wonderfully archaic and something that didn’t phase a veteran like Dimbleby.

Also Jeremy Vine’s first election replacing the retired Peter Snow, although not the same year as the glorious nonsense in 2007-08 when they tried going a bit wacky and having CGI rapping versions of Ming Campbell (“Yo, Lib Dem Ming with the Lib Dem bling” as Vine busts out some dance moves next to it) and most infamously of all the Wild West interlude where a cowboy hat/American accented Vine excitedly commented on a CGI Nick Clegg firing CGI tin cans outside a saloon. Both are on YouTube and fall into the So Bad It’s Good category.

Interesting breakdown, there's a thread from the time here:

https://tvforum.uk/tvhome/bbc-one-election-coverage-collapses-20603

Seems that just after that video ends it went to the legendary Emily Maitlis filling from a pub coverage. Not sure how that got on air, whether News24 and World took it or not.
