My LCD only shows pale black
I was working with my vaio (vgn cs36gj), suddenly the screen became pale black, it is on but only black, when I connect it to external monitor it works perfect, from that time, sometimes after turning on for 10 or 15 minutes LCD start working normally, restart and turning off it still works, but if I turn it off for a long time , it agains has no picture from starting up, it is on but only pale black.... how should I now that what is the problem? is it inverter? cable? I don't think that it is LCD problem because if it start working, it works perfect with usual color...
Is this a good question?
