Ok Dave please hold your horses, there is a little mixed up.
The IC I did replace was the TDA8356, the vertical output chip.

Fair enough, my mistake.

It is a dual input and output IC, have a look at the datasheet
please,
only
caps are on the supply line.
Boost cap has be replaced, very high ESR.
There was fresh solder on the legs, that is why the replacement.
The set was at another place before I got it to repair.
All electrolytic caps around the vertical and jungle IC has been
checked
for
the right ESR.

The snag is a capacitor can have an excellent ESR reading, especially
if
it's a dead short! The only way to reliably rule out caps IMO is
replacement. ESR testing is very useful, but not conclusive. With
vertical
linearity issues I'd suspect electrolytics before anything else,
especially
the small ones. Caps might show a good ESR reading, but fail when
under
working conditions.

Hello Dave
Will have a look again tomorrow, the funny thing is the one of the dc
coupled inputs from the 8365 is not there, also the output of the of
the
8842.
The only thing left is replacing the 8842 and holding thumbs, will
report
back.
Also I will change the few caps.
Customer his to decide it is his money.
Bert.
