Walter, Replace the vertical IC with part# 483520988531. Then replace D409 and D445 with part# 483513037094. R420 and R445 are the fuse resistors for these diodes and are part# 483511657109. Most likely the vertical IC was bad which caused the rest to fail HTH, LLW LeRoy Westlund Westlund TV & Electronics 97 North Main "Where there's a will,...
