Hi,
I think I found the problem: now the TV won't synchronize, no matter what you do to it, so I hooked up my old trusty (tube based) Oscope to the test point on the hor oscillator coils and, surprise, there is no trace of the two typical toes, just a plain sawtooth. Now that reminds me that when the TV was working, I saw the toes disappearing for the brief moment the TV lost sync... What does it mean?
Please excuse my poor English!!
Thanks
Giulio
