Title: J-Pac SYNC OK LED unlit
Post by: tibbs68 on February 09, 2005, 12:22:26 pm

I've completed my MAME cab and have fired up everything only to have the J-Pac SYNC OK LED unt. No picture to 20" Hantarex Polo. I'm also using s ArcadeVGA cards.

I know from the J-Pac guide no sync signal is being sent because it is out of range of the monitor but I don't know the possible reasons for this.

I've just changed the motherboard and this wasn't a problem before I changed it. Any correlation?

Nothing else has changed. Something blown in the monitor????

you may want to try emailing andy at ultimarc.com, i had a similar problem and he said there was a few j-pacs that went out towards the end of 2004 with faulty sync chips. This may be your problem
