I had a similar issue, my temp prob wasn't reading correctly, my display kept freezing, lights were on, on the apexjr and pb4 and I ended up sending it in for them to check it. now they want me to pay 135 for repairs on the apexjr, which according to them has water damage. which is bull cause I can access it via Ethernet which also they claim has water damage. I would prepare myself for worse case scenario when it come to sending it in for inspection and be prepared to pay at least 150 for repairs. Which in my opinion isn't worth it. Let me know if it works out for you just be prepared.
