Jerry,
I'll try to send you a PDF of the convergence board.
Here's what Force32 has on convergence problems on this model.....
SYMPTOM: Loss of Convergence, primarily effecting the red Convergence at
the left of the screen.
CAUSE: Corrupt data randomly being written to the Convergence EPROM.
SOLUTION: Replace the Digital Convergence Module with part number
00A10551-H007 / 4835 219 77623. Re-worked modules can be identified by a
yellow dot on the metal shield on the board.
THE ONLY WAY TO CORRECT THIS PROBLEM IS BY COMPLETE REPLACEMENT OF THE
DIGITAL CONVERGENCE BOARD WITH A REWORKED OR H007 MODULE.

I have this Phillips projection TV with a strange red convergence
distortion. Output stages OK, changed "spline processor" IC with no help.
Does anyone have a schematic of the convergence section I could beg, borrow
or download or any convergence related tips for this chassis?
Thanks!
