whats up,
looking though different websites i notice some are telling me to solder three jumpers and others four?
i have v4 SCPH-3001 SERIAL starts with U5
also the diagram show a different chip where M,N,O,P,Q,R,T,U,V,W. connects.
thanks for your help

u have 4 bridges to make
my guess is your confusion is caused by pal v4 and usav4 diagrams
