obc screen goes blank !

[Colin]

A couple of weeks ago the screen flickered for 5 or 6 seconds then went blank! but you could still hear radio  and switch it on/of , ignition of then on all was reset an ok .but today it started this again  and no mater what i did screen flickered then of  or just of ,  so i gave up an went to get out  but as i switched ign of and took key out i heard like i short crackle come from the speakers ???  any ideas whats up , thanks guys...    PS it does the same thing with tv, satnav, computer etc ..

Sounds like a screen issue as the tv and radio modules are separate in the spare wheel well hence the continued sound etc.
The crackling may be due to interference from a bad joint within the screen ribbon cable (usual problem regarding screen issues) feeding back through the system and to the amp.

Just thinking out loud

Thanks Rusty , not sure of my next move now , or how to go about finding someone to repair it, thank again .          Colin .

Sounds potentially like the screen backlight.
It is a CCFL type and would flicker before extinguishing.
Static sound could be the invertor trying to strike up

Apparently these can be changed, but don't think is a normal DIY job though

Colin, was this issue ever resolved? Currently experiencing the same...

Hi x5dom ,sorry about delay getting back to you  , my computer imploded and needed new parts , the obc has worked perfect ever since , cant fix if not broke , thinking back now I had that battery drain problem { a rear door relay } the two might have been connected , it seems a bad battery gets the blame for a lot of faults on an X , anyway good luck with yours .Colin ...
