Yes.  Bad connections most likely caused the STK's to fail.

Subject: [TechAssist] Sony KP-53V15 bowed pic on all sides.

What:  53" Sony Big Screen TV
Model:  KP-53V15
Chassis:  SCC-F19N-A
Made:  January 1995

Problem: Picture is Bowed in on all sides. Pinchusion Menu does work and
you 
can adjust the pinchusion, however the picture and the pinchusion are
badly 
bowed in on all sides of picture.

What I Have found so far:
I found numerous bad solder connections on the pinchusion board, also
found 
open 3.15A fuse on Conv. bd. Found many definite bad breaks on the 
Convergence IC's=STK 4278 and on IC1704 and IC1705 on convergence bd.

Thought for sure when I plugged set back in, that it would be fixed... 
However still have same problem. Do I need to replaced all the
Convergence 
IC's at this point. (The convergence bd was full on bad solder)???
