I have a Sega Super Hang On and when the picture is still it looks fine, like when your choosing the map picking the song etc.... As soon as there is movement the monitor flickers really bad??? Ive succesfully replaced a flyback and installed a cap kit last month, following directions from this forum. So i do have a little experience. Do you think this could be the power supply or a flyback going bad.

The monitor shows to be a wells garner 19k4093

any advice is awesome!!!
 
I am guessing you meant a 19K4903, and it sounds like cold solder joints on the monitor chassis. When you shake the machine some of the components temporarily lose connection causing the monitor to go nuts...

thats where i would start first, or maybe check the rgb connectors.
 
Im sorry, what i mean by movement is, as soon as the graphics start moving. The motorcycle driving etc.... Im not physically moving the machine, only picking a map and then trying to race around the track.. 'The whole time the bike is moving along the track the monitor flickers. Sorry for the confusion.
 
There is no confusion. The movement of the controls is enough to shake the machine and expose cold solder joints.


Does the flicker happen during the attract mode, when you are not touching the machine? Can you make it happen by playing with the controls whie the game is not in operation?

It happens both in attract mode and while you play. As soon as the graphics start moving quickly. It flickers the whole time???????
