We consider an effective theory with an SU(2)×U(1)×A4×Z2×Z4SU(2)×U(1)×A4×Z2×Z4 symmetry and investigate the possibility of a linking TeV-leptogenesis with a reactor angle |Ue3||Ue3| through spontaneous A4A4 symmetry breaking which is at a scale higher than electroweak scale under the framework of radiative seesaw. It has been shown that tri-bimaximal(TBM) can be obtained by forging vacuum expectation value (VEV) alignment of the A4A4. Especially, one A4A4 triplet scalar field with cut-off scale ΛΛ is added in neutrino Yukawa sector, which is responsible for the deviation of the exact TBM, to explain leptogenesis as well as a non-zero |Ue3||Ue3|. Above the scale of ΛΛ the leptonic Yukawa sectors will lead to the exact TBM. We analyze possible spectrums of light neutrinos and their flavor mixing angles corresponding to heavy Majorana neutrino mass ordering, and show that non-resonance leptogenesis at TeV-scale constrained by low energy data is achievable, both analytically as well as numerically. We show that only normal hierarchical spectrum of light neutrino would be strongly favored by the current Wilkinson Microwave Anisotropy Probe (WMAP) data, and also show that a relatively large |Ue3||Ue3| corresponds to the value of baryon asymmetry 6.2×10−106.2×10−10.
