Hello, This 10 y/o projection set has a curvature distortion at the top of the picture and the convergence is off I'm wanting to swap out the 2nd convergence module (9-1318-2A) but Tritronics says part is NLA. Will simply replacing the (STK391-020) IC'S at Loc IC4001 TO IC4003 usually correct this? I dont see any burnt components. I have no service literature and am seeking case history info on this model. Assistance is appreciated.
