I feel like I speak on here more than I speak to my wife.

Back in September due to looping issues I exchanged my columbus with a refurbished one off ebay.came with years warranty.For the last 6 months it has worked fine then suddenly now the radio screen will go off as well as sound but then come back.on again for anything like 5 secs to 20 secs then does the same again...it does this on all modes( reverse screen...sat nav screen) if I turn it off the clock goes in and out....I do not get the splashscreen.Soft reset and hard reset make no difference...Sent 2 messages via ebay to guy I bought it off but so far he hasn't replied.

Has anyone else had this strange going on.

I have had the unit out and disconnected but made no difference. 

Cheers

Damn, he probably loads firmware, then sends it out the door.  Rinse, repeat.

 

This with the DPF issue (hopefully making progress on that?) Not good.

Looks like a typical problem of power supply circuit on radio board.

Yes

I will have a search in my local area at Skipton to find someone who might be able to look at it for me.

My RNS510 has just lost all sound and the screen is black with an occasional flash of a thin horizontal line. Did you find anyone to look at your problem? I live 50 miles away but would worth driving over if any chance of a repair

Haven't found anyone yet who would be able to sort it.The last guy I spoke to said it would be to costly to take circuit boards out  and should just get aftermarket..trouble is I don't want to do that so at this time living with a faulty machine..at least mine does get 10 seconds of power before it goes off for 3 seconds then cycles 10 sec  3 sec..
