x-no-archive:yes

This is a UK spec Panasonic TC21S1R (Z5 chassis).
It works for several hour before the picture shows
some disturbance, then breaks up into snow. After
this, no channels can be located using the search
tuning, implying that the frequency has not just
drifted off but there are no signals at all. AV
input remains working.

The reason I'm having particular trouble with this
fault is that it will never show up when the set
back has been removed, even if heated with warm
air. At the moment I don't even know if the problem
is with the tuner or the IF strip.

Any help most appreciated. Please copy me on

Regards,


Colin
