Supergun Sync Issues
Posted: Mon Jul 24, 2006 1:02 pm
Hi All,
Well I finally finished my supergun. It's not the smallest, or the prettyist, but it does the job & my TV has a much better image than my fooked monitor.
The issue I have is that when testing a load of PCB's I found 2 or 3 that had sync problems. Not so much as a rolling picture, but almost like stripes of mess.
I tried these boards on my cab, and no problems.
I'm assuming these boards must be outputting a slightly different sync frequency compared to other boards, which the monitor is happy with, but the SCART TV thinks Fook Off!
Would putting a variable resistor in the sync line be of use, or would I need a circuit to do this (if so any ideas???)
Cheers all,
John
