I have an Olevia 537-B11, The LCD will only power on sometimes, the front led always comes on but it may or may not come on, it comes on sometimes if I leave it off for a week, I left it on overnight and it was working fine - when I woke the screen was off but the sound was on. I turned it off and havent been able to get it to come on since, but the blue front LED still comes on. I have checked the capacitors on the power supply none are bulged, any clues?
