Craigslist. Simply put. Choke down the ~$70 they’ll charge you, and do it. I’ve seen quite a few fixed right before my eyes (friends consoles) and they’ve never had an issue. They all still work unbelievably! I was skeptical at first, but it just… worked. Also check out the power pack. Reboot the power pack a few times, leave it unpulgged for 10 minutes, and make sure all connections are tight. When the power pack begins to mess up, you’ll get rings too (not sure if it’s two, or three, but it does throw rings). That spooked me once or twice before as well.
