This sounds like the light flickering rather than a faulty connection. You can check for a bad connection by tuning a nearby radio receiver to no station in the AM band. If there is a bad connection causing this you'll hear the sparking (in time with the flickering) on the radio.
Flickering is a common effect seen with neon indicator lights when they age and does not affect the switch function at all, so can be safely ignored.

I suggest try to connect your machine to an external display and see if its having also a flickering lines, if not it means the lcd display have a problem and try to load also to BIOS and see if its also having flickering lines, if its having also flickering lines means that the lcd is faulty.
The flickering is most likely due to a faulty fluorescent backlight. Once the bulb heats up the flickering usually goes away. Some bulbs are easier to replace than others so I would contact your local TV repair shop.
Hi,
The flickering light is nothing to worry about... as long as it is flickering it is considered to be "on"
If there is no light then you need to worry...
The light flickering is not something that you need to fix...
Flickering on the screen can be caused by defective hardware in the computer or by improperly installed software, but it can also be caused by interference from external devices. The following examples describe situations in which your screen could start flickering:
Screen starts flickering because of interference caused by devices which generate magnetic fields, for instance:
a TV set
a laser printer
another monitor
fluorescent lights
hidden power lines
Apart from interference, an incorrect setting in your system CMOS setup can also cause flickering. On some systems it is possible to distinguish between interlaced and non-interlaced monitors. The setup of your system should always be colour non-interlaced.
Proximity to the monitor of fans, air-conditioning units or other devices with rotating motors.
The number of devices using power from the same electrical line. Are you overloading the plug?
Monitor placed on an unstable surface.
Improper video drivers, this is a software problem, see section B
An improperly configured or a defective video card.
Reinstalling the video drivers
Start the computer.
Click Start, select Settings, and click Control Panel.
Double-click the System icon.
Select the Device Manager tab in the System Properties window.
Make sure that View devices by type is selected and locate Display adapters and Monitor in the list.
Click the plus sign (+) in front of both items to get a list of installed devices.
You need to remove every device by highlighting it and clicking the Remove button and OK when the warning message appears.
After doing so for both items, they should disappear from the list.
Close the Device Manager by clicking OK, and you will return to the Control Panel.
Double-click the Add New Hardware icon.
Click Next, select Yes when it asks "Do you want Windows to search for your new hardware?", and click Next twice to start searching for new hardware.
This will take a few minutes and, after it is finished, you will have to restart the computer. Windows 95 or higher will automatically set up the correct monitor and video drivers.
If the screen is still flickering, click Start, select Settings, and click Control Panel.
Double-click the Display icon and select the Refresh tab.
Change the Monitor Refresh Rates until the flickering disappears.
If the flickering remains, go to step C.
Troubleshooting
If it is possible, connect a different monitor to the computer. If the flickering disappears, it is a fair indication that the monitor is defective, otherwise go to the next step.
Set up the computer and the monitor on a different place in your house. If the flickering disappears now, it is most likely an interference caused by something in the original location. Check for devices which can cause interference.
If the flickering persists, check the setup of your system. If available in the setup, make sure that the option Monitor Type is configured as Colour Non-Interlaced.
