Check 2: Are all clocks operating normally?
Reproduce DVD-REF-A1(GGV1018) Title 1.
Verify the circuit described in Figure 2.
This check is the same for all DVD-V compatible modules.
Checks are to be conducted with a GND reference.
If locations listed under "verification location 2", can be verified, there will be no need to perform verifications for the loca-
tions listed under "verification location 1."
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 the vicinity of IC1506 (the section marked 2 in the circuit diagram).
