Pincushion Distortion: KV32XBR55
check for open R537 feedback loop from Q505 to IC531
Since you have replace most parts that usually fails on the A board. Check
the feed back loop above.

Subject: [TechAssist] Still unsolved mystory:
> SONY KV32XBR55: Replaced Q505(shorted), R571(open), IC531,
L501(recommended replaced), and checked and resoldered D512(Checked Ok). No
schematic. Still has bowed sides. Pincushion and Horiz.Size in service menu
wont adjust (numbers change), all other adjustments work. If I jump across
L501, I get almost full scan but I can still see that pincushion is out of
alignment. Any thoughts to getting this set out of here would be greatly
appreciated, Thanks, Neil
