I installed this a few years ago on a PU-8 (first diagram) and everything went smoothly. Points are all isolated, nothing to worry about, etc. Powered on, suddenly had no video or audio. Checked everything, double checked the connections on the Pro Mini, everything was fine. I just recently pulled this thing out to look over. Did it fry my video encoder or graphics chip I'm wondering? Also the laser stays faintly lit,
