I'm in a situation where I received my L3+ in early November. It was set up and running fine for 3 days and then the L3+ stopped working while I was away from home. When I returned home, the unit wasn't powered on, so I unplugged and replugged the power supply from the surge protector. Next thing I know, I saw something bright light up through the front intake fan of the L3+ and black smoke immediately came out through the back of the unit. I immediately unplugged the power supply and messaged Bitmain for support.

I spoke with Bitmain's customer service and was given permission to disassemble the unit and take photos of the hash boards. Upon disassembly and removal of the hash boards I noticed 2 of the hash boards were burnt. It took a week to get a response from them after sending them photos of the hash boards and now they are saying my warranty is void because of the burnt hash boards. The unit was never overclocked, modified or tampered with in any way.

Anyone have a similar experience? Is there anything I can do at this point?
