HI,Can anyone advice me? I have a problem in machine constant MH2000,after changing battery of system, now constant key in cabinet not worked & we can't edit constant value, machine give an erorr M01 or M02 and O23.
please if possible help me.
Thanks a lot,
I was run the diagnostic test and the result was:
"Running test: 5= proc mod V24
Vart NR = 1 33800
Detected Error - Number is = 013"
So i was replace the memory card & CPU card, and ewerything looked fine and the same result!
And when i was look under the flatpanel, i was found that one ic was only fitted with one side of the ic pins(7pins of 14) in the socket. I was notice that one of the pins just touch the socket, but i was sure that i had found the the problem. So i replaced the ic in the socket(14pins of 14), but the problem was still there.
Then i was take out the 7 pins again, and now i was sure that the 7:th pin not were touching the socket, and now the machine run again without the M02 errorcode?
So now i wonder what the ic:s function are? The machine seems to work well without it? And when i run the diagnostic test, i still got the same errors? But the machine runs like it always did?
The ic i placed at the upper left corner, and marked with: CD 4093 BE RCA H 340
