Hello out there.
This is my first post so go easy chaps
I am not a complete novice at some easy electronic repairs,but this one has stumped me.
I have the Roberts Duologic digi Radio which has gone dead.
Here's a list of things i have done up to now
1/Bought a new power supply transformer from ebay ,still doesn't switch on at all.
2/Bought a set of new Batteries still doesn't work.
So i decided to open the back up and it seems there's a wire which doesn't appear to be connected to anything.Anyway i will provide photos of the said wire,with the hope that someone knows where this wire needs reconnecting to.
Thanks you in advance

You don't say which wire but at a guess it appears the shielded with the black heatshrink section.
If this is the case then it looks like an antenna cable with a loading coil as it originates under the shielding.
One end connection only required.
You may find on reassembly that it is meant to lay above the two long spacers on the opposite casing.
Nothing to do with switching on or not though.

Yes that's the correct wire which isn't attached to anything as you described.So its not that then which is stopping the radio from switching on.

Hi I have just read your post.The inner cable of the thin screened cable from the DAB/VHF tuner module aerial connection. It has a black round choke fitted on the module end.The outer screen of this cable is isolated and not connected anywhere. At the other end of this cable has the screen soldered to the tin ground plane which acts as an earth connection.. The inner of this screened cable should be soldered to the circular solder tag which in turn connects the telescopic aerial. I can only think that when you opened the radio these two top connections broke away,leaving the tuner without an aerial.I hope this helps you. This fault would not stop the radio switching on.
