My laptop got a little impact and afterwards when i turned it on, nothing was displayed on its LED(only the blank screen(Dark blue). Also, an external monitor works fine.
How can i test whether the problem is the "converter" or the LED?
Thanks in advance.
I should add some update on this!
After two days that nothing came on the screen, suddenly when i was working with an external monitor,,the display was worked.
But the problem is that after some seconds the display goes and comes! does it mean that the converter has been disconnected? it is very strange that after two days working,,without any movement of the LED, suddenly it worked.
I would appreciate any idea.
