I can't agree there. When I used to repair TVs and video recorders and
the like, I (like others) tended to find that different makes had their
own particular favourite stock faults.
In that case, for example, if you got a Ferguson ICC9-chassis TV on the
bench with no EW correction and excessive width, you'd go straight for a
particular electrolytic somewhere around the scan drive circuit.
Annoyingly enough I can't remember which one and my telly has just
started doing that...

I find those sort of tips totally useless!. There could be many causes of
'no vertical deflection' (or whatever), the fact that _once_ it was
caused by a particular set of components doesn't mean it always is. Many IC's and transistors show little to no
visual
indications that they are shorted inside. I don't
know how one can find these without understanding
where the resistors are in the schematic and how
the resistors are being used.
Actually, many servicepeople rely on compiled tips for servicing.
Something like "If there's no vertical sweep, replace R302, Q401 and C213".
