  We report on the 0.1--100 keV BeppoSAX observations of two nearby LINER
galaxies, Sombrero and NGC 4736. Chandra ACIS-S observations supplement this
broad-beam spectral study with a high resolution look into the nuclear region,
and show a dominating central point source in Sombrero and a complex X-ray
binary dominated/starburst region in NGC 4736. A compact non-thermal radio
source, present in the nucleus of both galaxies, coincides with the central
source in Sombrero, while in NGC 4736 its X-ray counterpart is a much fainter
point source, not the brightest of the central region. On the basis of these
and other results, we conclude that the LINER activity is linked to the
presence of a low luminosity AGN in Sombrero and to a recent starburst in NGC
4736, and that Chandra's spectroscopic capabilities coupled to high resolution
imaging are essential to establish the origin of the nuclear activity.
