|Okay so I bought a used computer off ebay a QosmioX505 and it works great while its plugged in, but if its not plugged in the backlight will not power on. Also while its plugged in if I adjust the monitor on my laptop it will go black momentarily, and occasionally it will just stay black(backlight power goes off for good) and I have to restart the computer. |
I asked someone at geeksquad and they said its either the LCD inverter or the LCD, but it would cost 50 or more dollars for the diagnosis. So I thought I would come here first.
