Screen doesn't always turn on
When I turn on my computer, sometimes the screen wont turn on. By that I mean there is no backlight and from what I can tell, no faint picture on the LCD. I know that the computer is starting up fine since I can login and play a audio file on my desktop.
The only thing I've found that fixes it is resetting the SMU and PRAM but that doesn't always work and the next time the computer is restarted the screen usually wont turn back on.
Any suggestions for what could be a cause of it? I thought it could be the power supply, inverter or LCD but I'm not sure since it sometimes works.
