Radio issue

[RM_Marine]

So first big road trip for a while and put the radio and got radio but the screen is black and its not the brightness, there is a flickering at the edge and the tuning moves and changes channel

But whats stranger is that TV works on it and so does the satnav

Any ideas

It did come on after a hour but went off after a few mins

Have you got any USB adapters plugged in or powered up near the radio? The high speed switching on cheap ones can interfere with reception, some LED lights can too. Just a thought

Thank you and I'll have a check
