The problem with my DVD4 is that the display screen automatically goes off in around 1 minute. At the time when it is powered on, the display is perfect and clear. It appears that the screen has gone in the background but i cannot see it as the illumination is off like in some kind of energy saving mode. The sound in the audio and video remains normal. The display doesnot turn on even by pressing the keys on the player which i thought could be in the sleep mode. Could u pls suggest the remedy ? REHAN
