Hi,
I have the same problem. But a bit more complicated. One day my screen went comletely dark but I could still see the pic. After replacing an inverter it was ok. After about a month my screen started to flicker from time to time, just like a little flicker then the flickering become more often and after 2 weeks the screen went dim again. So I closed the lid reopened it was ok again for sometime then repeated. After another week of playing with the screen it just went dim and reopening the screen wouldn't work anymore. I thought it could be the backlight problem so I bought a new screen. After 5 minutes the new screen went dim again
I closed the screen, opened it worked ok. Then when I switched to my external and back again the laptop screen lit up for a sec and went dark. Switching between screens didn't help so I closed the screen, opened it works
so now it's been like an hour and it still works but I'm afraid the issue still exist and I'm afraid that after sometime it could get worse. So I don't have a clue what could that be. And even if the old sreen was bad how could the new inverter fix the issue for sometime?
BTW the screen is second hand so what if that screen could have the same issue? The person who was selling it said it was in great 100% working condition though.
Or could that be the cable? arrrrgh.... I really need a help asap please.
Thanks
