2013 Cotswold 12v Electrical problem?

We have a Peugeot Autosleeper 2013 Cotswold.
Recently the supply to the 12V charger socket in the front and rear of the van has stopped working as has the TV.
We have traced the wiring, checked the fuses that we could see but still to no avail.
Can anyone shed any light please?
Thank you

Hello and from Leicestershire. Sorry cannot help with your query, but....

You will get more replies if you say hello in the introduction thread as requested by the forum.

Check every connection from beginning to end and use a volt/multi meter at every connection to see if the supply is available.

ie: check there is a voltage at both sides of the fuse.

We've had a similar problem, discovered to be broken contact in the actual plug serving the tv.

Thank you.
