Lumix G85 Sensor Issue?

My G85 has an intermittent issue: Sometimes blue pixels flash randomly on the screen. Other times, vertical bands or curvy moire patterns show up. The problem tends to appear on power up. It tends to go away if I take the lens on and off. It also generally dies down after a few minutes of using the camera. I purchased it from 123-easyship on Amazon Canada in December. I think it's a sensor issue, but wonder if it could stem from the auto-focus system in the lens or at the contact pins. How can I get it repaired?​Processing img li8jpw1vrax41...​Processing img einea4f1sax41... via /r/photography https://ift.tt/2A1rwsA
