Does somebody have any guess??? How could I check the tranformator?

sincerly the desperate max



Still looks like capacitors problems, actually, reverse polarity like the other guy said. if not could be related with temperature, that will open a different approach, you should consider the transistors as well the tdas, and I recommend a oscilloscope to check the wave forms
