I recently successfully RGB modded my PC engine but now it doesnt power on anymore, except when I turn on my megadrive also (on the same RGB scart divider as they bleed trough each other, thus I can see it also turning on and working normally (as colors are still intact) ). I've tried different power supplies, but no luck. What can be the problem? And how could I fix it? Edit: Sorry for double posting and wrong section, I dont know what went wrong.
