Reversing camera woes

[gilbaro]

I replaced the rear brake light the other day and now the reversing camera has stopped working. I am just getting a blue screen. It is a single camera permanently on so no reverse feed.
The wiring is totally separate.
The camera has a 4 pin aviation plug. checking with meter I get 11.44v at video pin 2 but nothing at pin 1 +ve.
The only thing I did involving camera lead was to disconnect and reconnect.
Any ideas? I would rather be enjoying the Cornish sunshine

Always worth turning everything off and on again, also disconnect and reconnect the camera again (checking that it only fits one way) ... probably not much help but at least it will bump your thread and maybe catch someone else's eye

tried that but no effect.
I presume that camera has a separate fuse but no idea where.
Anyone any ideas where fuse would likely be on 2015 Elddis Majestic 125?

It is likely to be a problem at the brake light end surely but I have read fuses are often in the b pillar if that helps.

Does the camera have a ground wire that you have disturbed maybe?

When ours went off it was because someone (not me) had changed the channel to channel 2.

If you are using a terminal block check joint as when making the connection it could be that the insulation has been caught rather than the copper
