##:OK or NG
-
If nothing appears on the screen:
There might be a problem in communication or abnormality in the display microcomputer.
-
If NG appears somewhere:
There might be defective connection between the display microcomputer and image ROM.
For instance, NG appearing with respect to the data bus does not necessarily mean data bus connection is definitely
defective.
Where the address bus is the reason for NG appearing, an error could still occur when checking the data bus.
