SDV-P7
Check 7: Is the microprocessor operating normally?
Verify the circuit described in Figure
7
.
This check is the same for all DVD-V compatible modules.
Check the conductivity of both the "Verification location 1" and the "Verification location2."
If the result is not satisfactory, check to see if there are any problems with the resin flux cored solder, parts and compo-
nents, in areas where a problem occurs, for the overall sequence of "output – input" of the checked location.
