Here to pick your collective brains again.
I have an older model Sony Vaio Model ( VGN - NR21J/S )
I turned it on, only to find the display wasnt working. It is completely black - no hint of light coming from it at all.
I've tried adjusting the brightness to no avail.
I've tried connecting it to an external display, but there seems to be no signal coming from it, so i'm wondering if perhaps it could be the video card rather than the display itself ?
If this is the case, is there anyway to check other than just swapping it out with another one to test it ?
Any tips or advice would be very much appreciated.
