First the vertical would narrow,hitting set temp. restored it. Usually the 7 pin vert. IC at rear developes cold solder (IC# 7401). Resoldered it, powers up.Top of vert is distorted. The original vert IC is a STV9379. My Philips stock has the same LOOKING vert IC's ,different numbers:483520988531/TDA9302H. Are these all the same? Phil Bader -- Philip Bader Jan Phyl TV Inc.
