Flickering Laptop Screen - How to Fix LCD Laptop Screen that Flickers Randomly

When a standalone LCD monitor flickers randomly, the problem is usually the backlight. When the same thing happens in a laptop, the cause is a defective ribbon connector cable.

Remember that in a laptop the display screen is separate from the main case that contains the keyboard, hard disk and other electronic parts.

The laptop screen is embedded into the lid of the laptop, and by constant opening and closing, the LCD ribbon connector cable gets worn out.

Once the damage sets in, the cable is unable to relay video signals properly, and so the screen images flicker randomly.

Luckily, there's an easy fix for this: Just replace the ribbon connector cable with a compatible part from an OEM manufacturer. It usually costs $15-20 and is far cheaper than replacing the whole screen.
