Fans force air when turning on PBG4
Watching the Audi Channel one night the PB screen went black (that was before it stuttering on the internet connection).
When turning back on, the fans just keep blowing air and there is no display. Screen is black. No beeps.
This is 15" PBG4 - had for a bout 4yrs. Could the screen inverter have gone or is this a logic board issue.
Is this a good question?
