Hi guys

 

My Columbus radio either wont turn on or it'll come on suddenly with an annoying thud (like a guitar plugging into an amp). or it'll stay on for 5-10-20 minutes then power off again with the same noise..!!

 

I've taken the radio out whilst its been on, and gave all the wires a good wiggle and nothing happens, I've tried all the fuses to make sure they're all good, I've swapped out the radio fuse just in case but nothing seems to have made a difference. I've also replaced the ignition switch................

 

temperature doesnt seem to matter or if i go across any bumps etc......Its possessed I tell ya...!

 

I dont really want to buy a new head unit if the issue is with the electrics............. Any ideas welcome.

 

Cheers guys.

 

 

Typical problem with Columbus RNS510 units. I have a friend quite close to you that should be able to have it repaired, will send you link on PM

Cheers.....

I think I've managed to fix it...!! 

 

Will have to wait a few days to make sure it doesnt fail........ Gotta love Google and Youtube..!

what video did you watch?

Hi guys...

 

Good news is that the radio is fixed...!

 

basically once the radio is out, undo a few screws at the top and side and you’ll be able to lift the CD player out, be careful of the ribbon cables attached to it.

 

The chip that I ran the soldering iron over is the small one (see attached photo), put some flux around the contacts then I ran the iron over the contacts very gently a few times with a very pointy tip. 

 

Put it all back back together again and hey presto...!

Hi Bifferbob 

 

Could you clarify exactly which bit you put flux and ran the soldering iron over? 

In your photo in the area marked in red there appear to be two small chips and one larger one - that's if they are the square things!!

It it necessary to use a really small soldering iron?

Asking questions as we have removed the now non working Columbus unit to try to repair it.

That said we may install the unit I purchased from Autotech instead!
