Supergun CGA to VGA synch problems

Postby zumbito » May 6th, 2016, 12:03 pm

Hi,

I am trying to build myself a test rig, and purchased a CGA to VGA board to connect the supergun to a LCD, problem is image is flickering and don't really know why:

I thought it might be the synch cable, I tried to solder a potentiometer to play with it, but still no progress (I am not really sure if I installed it correctly... :oops: )

Any ideas?

Ok, solved. In case anyone has the same issue, problem was I was powering the CGA to VGA with a different PSU. The moment I just connected it to the Jamma harness, flickering went away. :D
