Roland practica

Hi everyone.knows anyone what does it mean error 5003 or 5006 .regards

 

Hi sir
Hope you are well
The only way to know what type error is entering to the console Service Menu
Most of the type the software coming in the EPROM is corrupted.
The only way is erase and introduce again the software parameter .
However test the battery for 3.5VDC, is the Voltage is o,k NOT replace, otherwise Replace battery
CMOS for backup, you must have 5 minutes to do it, contrary you will loose the information.

 

Hi chock.this problem made only in the middle of the day.at the night my practica is ok maybe that people are sleeping and the tension is ok

 

Hi sir
if the problem is Only the m day, i strong suggest that you test the power Input with DMM like FLUke or other similiar
for the 3 phases input.
and see if there are the tolerance for about + o -10% . This can cause disturbancess to the main trafo
and consequently in the secodary trafo, for that reason all circuits connectadas, can be alterated and producint
phenomenon transistory(terms in electronic engineering)
Let me know any result, or question
