This unit came in for intermittent vertical collapse, tapping affected. I did
confirm the problem, but
when it came time to work on unit, I could NOT get it to act up. I replaced all
the caps in the vertical
section and after the last cap, the unit would not stay on. It would start to
build high voltage, then
shutdown. Unplug and try again and same thing.
Before this occurred, the vertical IC heat sink was really warm, so I replaced
the IC (TDA8174) and no
help. I did use Zenith #221-00992.
Also, is there a surface mount resistor between pin 2,4 of vertical IC, that my
solder wick may have
eaten?
Would anyone have any advice before I tackle this thing on Fri?
Thanks.
