Ok I have compiled some information I hope will help me get a better understanding of the self test results. Well to start with on the self test results page you are presented with 8 bytes that indicate individual test results like this: x1111 00000 00000 10000 00111 00101 01010 10101 00111 10000 00110 00xxx 00000000 00000000 00000000 00001100 00000000 00000000 00000000 00000000 The first byte indicates the test results for 00-04 as in: x1111 ^^^^^ test 00000 number 01234 A number 1 indicates a fail and a 0 indicates a pass. X also appears to indicate a fail. The last remaining 2 rows of numbers elude me at the moment. Each test can be run individually by pressing the ignore button at the results screen and select "system" (F4) then "etc" (etc) then "debug" (f1) From this screen press "run" then type the test number and press enter Results at faulty boot (Without pod plugged in): test 00000 00000 11111 11111 22222 22222 number 01234 56789 01234 56789 01234 56789 ------ ----- ----- ----- ----- ----- ----- Result x1111 00000 00000 10000 00101 00101 test 33333 33333 44444 44444 55555 55555 number 01234 56789 01234 56789 01234 56789 ------ ----- ----- ----- ----- ----- ----- Result 01010 10101 00111 10000 00110 00xxx Failed: Information ------- --------------------- 0 :Clip test :Failed 00001111 11111111 11111111 11110000 1 :? :Failed 00000000 00000000 00000000 00000001 2 :? :Failed 00000000 00000000 00000000 00000001 3 :? :Failed 00000000 00000000 00000000 00000001 4 :? :Failed 00000000 00000000 00000000 00000001 15 :? :Failed 00000000 00000000 00000000 00000001 22 :? :Failed 00000000 00000000 00000000 00000001 24 :? :Failed 00000000 00000000 00000000 00000001 27 :? :Failed 00000000 00000000 00000000 00000001 29 :? :Failed 00000000 00000000 00000000 00000001 00000000 00000000 00000000 00001000 00000000 00000000 00000000 00000000 31 : :Failed 00000000 00000000 00000000 00000001 00000000 00000000 00000000 00001000 00000000 00000000 00000000 00000000 33 : :Failed 00000000 00000000 00000000 00000001 00000000 00000000 00000000 00001000 00000000 00000000 00000000 00000000 35 : :Failed 00000000 00000000 00000000 00000001 00000000 00000000 00000000 00001000 00000000 00000000 00000000 00000000 37 : :Failed 00000000 00000000 00000000 00000001 00000000 00000000 00000000 00001000 00000000 00000000 00000000 00000000 39 : :Failed 00000000 00000000 00000000 00000001 00000000 00000000 00000000 00001000 00000000 00000000 00000000 00000000 43 : :Failed 00001111 11111111 11111111 11111111 47 :Hardware test :Failed 00000000 00000000 00000000 00000001 00000000 00000000 00000000 00001000 00000000 00000000 00000000 00000000 50 : :Passed (Does x mean doesn't matter?) 52 : :Failed 01000000 00000000 00000000 00000001 53 : :Failed 00000000 00000000 00000000 00000001 57 :Test invalid 58 :Test invalid 59 :Test invalid Results with 180Ohm resistor on pins 12-14,11-14: Fault 00000 00000 11111 11111 22222 22222 number 01234 56789 01234 56789 01234 56789 Result x1111 00000 00000 10000 00111 00101 Result 01010 10101 00111 10x00 x0110 00xxx Fault 33333 33333 44444 44444 55555 55555 number 01234 56789 01234 56789 01234 56789 Another thing to note is that there is a clear warning on the interface buffer sockets which state that J1 and J2 should not be swapped as permanent damage will result. On inspection if these are swapped J1 will put -8v onto IC U8 (AM6687DL) pin 1. Pin 1 is the non inverted out of this high speed comparator which would likely damage it.
