Hi leatherface96

I have same problem with you, I was repair and fix now. TEst will appear cause system fail communication between akses 1,2,3
system must be communication before ( self test ) and make sure all fuction done and unit ready for use
Fail communication due to about line on mainboard broken , electronic component ( demage or fatique ) and program on IC lost
to make sure repalece broken akses3 and put on other unit, copy setup first.

perhaps my opinion can help you
