Even TEST MODE (BRIGHT) = 79h will be acceptable. Even TEST MODE (CONTRAST) = 7Eh will be acceptable. TEST MODE (GAMMA0) Due to dispersion of components, adjustment may be able to be obtained at two points. At that case, select the adjustment position near by the volume center position and check that the voltage value of A (black to white peak) exceeds 2.40 V
