( how to detect problem by test pattern )
1. When phenomenon has no image ( no show on screen either ), " whole white
pattern " indicate and diagnostic the problem also find to close problem PCB.

[ Method ]
a. Turn off the main power SW.
b. PX600/PX60 series : disconnect DG5 connector of DG PCB.
c. After that, turn on the main power SW, it will show white pattern.
[ diagnostic point ]
1. white pattern show on screen : Tuner circuit or DG PCB problem.
2. white pattern does not show : Plasma panel or D PCB problem
( it may happened on SC PCB )

[ diagnostic point ]
1. To be cautioned line size thin or thick. Depending one the size, it will cause
by Panel or D PCB.
2. Most cases will affect by D or DG PCB for equal span. It diagnostic
by Test pattern indication.
[ diagnostic point ]
when noise shown on whole screen, it may difficult to judge and specify the cause
of problem. However you can review it by SU PCB or SD PCB in order to find
which PCB will be affected. Also there is case of other factor.
