Title: Core Grafx RGB Amp Video Output Issue - White Roll/Flickering (Video)
Post by: lamb2k on June 30, 2023, 05:33:03 PM

Hi everyone,

I am currently experiencing an issue with my Core Grafx through an RGB amp. The video output presents a white roll or flickering. The game is still playable, but this graphical disturbance is quite disruptive and definitely hampers my gaming experience.

I've tried basic troubleshooting like checking the cables, connections, and even tried different monitors, but the problem persists. Could anyone provide any advice or potential fixes for this issue?

Your help is greatly appreciated!

Can you run the Core over composite without the RGB add-on? My initial thought was power supply amp draw is too much. Also, does using a Hucard instead of TED make a difference?

Thanks for the response. Let me give the Hu card a try.
