Quoted from GorillaBiscuits:
Also in the black screen club. Jiggling the cables going into the unit usually fixes it, did not consider the extension cables. Hope that helps, as the cabinet itself looks pretty hard to take apart with all the hot glue. Thanks for the info!
Yup, sounds just like mine, it seems that Jiggling the cable solution has stopped working for me. I don't mind taking it apart but would love to know what I am looking at.
