My Toshiba Tecra A9 screen is dim, almost completely black, but you can just make out some display, this happened recently after I had been using data projectors a lot, then one time I took out the VGA cable and screen didnt come back on laptop. External monitor works fine, I have checked all display and power settings etc. Some websites suggest dim screen could be backlight or inverter, but the wierd thing is when I change the screen resolution, the screen will work perfectly for about 5 seconds and then go black again (also when I first boot up, the screen where I enter my password, sometimes displays...but then goes black when I enter it). Ane ideas?
