Sorry to bump an older thread, but I’ve found a device that seems to completely eliminate the intermittent black screen problem. It’s an old Radio Shack brand Video Enhancer / Stereo Audio Mixer (Cat. No. 15-1961), connected between the Genesis (or distribution amplifier) and the composite video input of the Koryuu, with the slider set around 2-4. I’ve only tested it with the VA6 Genesis so far, but the image on the HDTV is rock-stable no matter how long the console’s been running. I did verify that the intermittent black screen symptom returns if the device is removed from the signal chain.
It seems the device uses discrete components for the video enhancer function; a slide potentiometer, three transistors, several capacitors and resistors, and one diode. If anyone is interested I could provide pictures or try to make a circuit diagram (but I’m far from an expert there).
