Do you still have the bad Flyback? You can try sending it to me if you can
supply a schematic of the FBT area with it, and a Brief Report of How you
determined the FBT to be failed. (Ringer, shorted Winding, cracked case /
arcing , internal Diode shorted /open etc) & I may be able to get you
something made up. It would be a while though before you got something to
test, and the one you provide must not have the Ferrite damaged, and be
packed accordingly.
No one really has replacement FBT's for these Pioneers, so maybe me and you
can help "Pioneer" these ?

I just found out that they do not sell the flyback separately for a
different set. They want $695 for a brand new deflection board for an
SD-P4691K model. Ridiculous!!! I will not be recommending Pioneer
projection TV's, even if they have a better picture.
