Note : EEPROM
EEPROM(Electronically Erasable and
Programmable Read Only Memory) is a non-
volatile memory which keeps memorized
information even if power is turned off. It can
change the contents electronically.
To change the contents, it uses higher
voltage than normal, and it can not change a
partial contents. (Rewriting shall be done
upon erasing the all contents.)
There is a limit in a number of rewriting.
If Check Point 1,2 do not improve the symptom, replace Main PCB.
Check all connectors.
(loose connector or incorrect wiring)
Check any shortage or corrosion on PCB.
When power is on and there is some below case.
