Hey all,

I just got back a Neotec 27E I had repaired by Chad @ ArcadeCup for San Fran Rush. I've never seen this monitor as of yet since it was dead when I purchased the Rush. I did however have a converter running to an LCD temporarily while Chad was repairing the chassis and it worked great and had a nice picture.

I've got the chassis back in and I can get a picture but for the life of me cannot get it to sync. Nonstop vertical and horizontal roll no matter how I adjust the remote board. I've sent Chad a PM to see if he has any insight and in the mean time I thought I'd post here to see if anyone has any experience on this.

The cable that goes from the 6-pin molex coming from the harness to the video input on the monitor chassis was missing so I made my own. It appears Rush has composite sync - I assume this means that sync wire should only go to pin 6 labelled as S.H. and not split to both pin 5 and 6 (Vertical and S.H.)

Doing some other reading is it possible I have a bad video ground? Would this cause the nonstop rolling?

Thanks for any insight,
Jigz
 
Update: Swapped Rush mainboards with my other Rush and had no problem getting the video to sync and stay. Oddly enough I can no longer get even my converter board to work on the first board....Seems I might have done something to this other Rush board. Might be time to see if anyone repairs them or anyone have a working spare?
