the picture on my sony kdf-e60a20 is not as bright as it should be. i have the brightness turned up to 95 and still no good, its really noticeable when the scene is dark like something at night, the pic is almost completely black. i am 100% sure its not the lamp, i bought a new one and also took the one out of another kdf-e60a20 where the pic was perfect and still its dark on mine. any idea what could be causing this? your help is much appreciated.
