The energy balance of strongly interacting surface electrons on liquid helium under cyclotron-resonance excitation
 is theoretically studied. The Coulomb interaction is shown to induce temperature bistability of the electron
 system, if the magnetic field and electron density are high enough. Surprisingly, bistability appears already for
 quite low average kinetic energies, when nearly all electrons occupy the ground surface subband. The electron
 temperature Te, as the function of the magnetic field B, exhibits hysteresis and bistability jumps in a certain
 range of the microwave power. Above the threshold microwave field, the line shape Te(B) is shown to be sensitive
 to details of the ripplon dispersion at large wave numbers.
