Turns on, but won’t connect via Bluetooth nor play music w/ aux cord

I had a trouble getting my JBL Pulse 2 to charge last week, and when I finally got it working and turned it on, it refuses to connect via Bluetooth. When I press the Bluetooth button, the crazy light show starts as mentioned in other comments. I decided to see what happens when I connect the speaker manually using an aux cord from my phone directly into the aux port of the speaker…. no sound!! Is there any fix for this?! I really enjoy how this speaker lights up but very disappointed in how fast this product stopped working. JBL has said it is out of warranty (was purchased as a gift to me at the beginning of January 2017) so no luck there. Thank you in advanced!
