These explanation of synchronize problem IC are relating with 1. Depending on location of damaged screen, it can identify which PCB problem.

Test pattern indication is recommended in order to make sure however it will possible to cause by Plasma Panel.

problem OSD position wrong cause by DG PCB
OSD indication position is wrong
[ diagnostic point ]
1. Current TV program screen show on TV channel program guide,
it is controlled by DG PCB.
[ diagnostic point ] 2. OSD indicate position is made by DG PCB which is analogue data.
When voltage charge does not match on scanning electrode and writing
electrode, electric storage does not normal on inside cell of Panel.
and it does not radiate as normal operation.
therefore,
1. SC PCB what request order to scan electrode.
2. D PCB what control discharge.
those factor will consider cause of problem.
