The equations for the light-induced Freedericksz transition threshold of the initial homeotropic director configuration are obtained and the solutions to them are found in analytical or numerical forms. Due to the surface charges the threshold value increases if the nematic static dielectric anisotropy is positive or decreases in the opposite case. The threshold value depends also on the director anchoring energy, Debye screening length and cell thickness. For each given value of the light wave electric vector which stabilizes the initial director configuration the critical value of the surface charge density is found at which this configuration is growing unstable.
