Question about Gateway 7330GZ Notebook
As though there was a loose part or faulty cable.
Has there been an issue with this?
Your problem could be a faulty backlighting panel or the power connector for the backlight needs reseating.
There are two connectors on the LCD that are connected to the motherboard, one for the video signal and the other for the backlight power supply, reseat this connector and hopefully your problem will be fixed.

A flickering screen may be caused by the computer detecting incorrect display settings as it starts or returns from sleep.
It can also come from changes to the screen resolution settings caused by a new program or update installation.
Verify screen resolution before assuming the issue is hardware related.
Next to the display screen behind the plastic screen bezel is a small component called the inverter, which supplies power to the screen backlight.
The flickering indicates the power is not reaching the backlight.
To fix the issue, replace the inverter.
The wires and cables traveling from the display around the hinges and into the motherboard tend to wear at the hinge area.
Over time, the opening and closing of the screen causes this wear.
The solution is to disassemble the plastic casing of the laptop, reorganize the cables so they have no interference from hinges, or replace the cables and connectors with new ones made specifically for the computer make and model experiencing the issue.
hope this helps
