My Dreamcast was turned on after almost 10 years, it was fine at first, then I got a hdmi converter cable and after about 1 hour of testing it started to get a slow-mo image with a few artifacts, but the sound is fine at normal speed. It reads games fine, it’s just slowed down and artifacted even in the logo screen. Was wondering if this is a reaballing situation or if I just need to replace the caps.
