I already changed the power supplies and it still happens and with the same problem

Did you check the voltage after them? The same error occurs when one of the powered boards has a bad connection.

Hi:

please as say the colleague, only that you must test the secondary in the main transformer, if the VAC, are in Tolerance about 10%, and fi they are o.k test the regulated power supply very well, the tolerance must be exactly for 0.7% Up or down.

example, if you are measuring : + 24 VDC, and you get 24.3 or more or vice versa, like 23.8 is FAULTY, the regulated power supply.


CLEAN VERY WELL THE EDGE CONNECTOR, THESE REPRESENT THE 75% OF FAILURE IN ELECTRONIC FAILURES!

Must be checked the Filter or electrolitic capacitor for BULGED !
