Hi,
I have a Toshiba Qosmio X550-8100x. I bought it a year and a half back. It fell down once from my bed, and since then, though not immediately, the laptop screen backlight began flickering when only on battery. When on AC charge + battery it rarely flickers.
When it is steady and not moved the screen is fine. But when it moves slightly the flickering begins and the backlight dies out. After I put it to sleep and start it again the backlight resumes function. Any idea on what the exact problem could be ? Could it be a loose cable ? Thanks for your suggestions.
