i have fitted a new lcd to motorola t280 timeport today and the lcd does not light up very well. i am guessing that the lcd i have purchased is at fault. the keypad all lights up fine it is just the lcd that has a small dim blue light around it. i do not know the features of this phone that well but i cannot find any lcd dimming settings.faulty lcd ??? any suggestions please.
