O.k. so what conclusion could one draw if this warm up
period is taking very long (15 minures)?

How do you define warming up?

When I switch the tv on in the morning (after it cooled of all night)
it takes about 10 minutes until the picture comes on. (the voice
does not have this delay) and this delay has become worse in
the last years. It's not a Sony it's Panasonic tx-w28r3


Examine the CRT PCB and see if there's any small chokes in series with the
heater - if so replace with wire links and see if the CRT warms up any
quicker.
