Hey guys - I was given a Rasp Pi 3 B+ from a friend that said it "worked" the last time he played with it. All I'm getting is the solid red light and it doesn't appear to boot. I have some experience running PiCorePlayer on several other ones I own. I've read several forums on troubleshooting and watched a lot of videos, but they really didn't offer much. At this point, is this thing just dead? I'm also getting no video out of the HDMI port. There is a 4 prong junction on board with no jumpers on it, but I haven't checked my other units to see if this is normally occupied or not. Any ideas, or just pitch it. Thanks.
