Question about E-Machines M6811 Notebook
How can I brighten my screen on the HP ze5629us? I have change the inverter and the screen is still dim. The Picture quality is poor and I have a problem with the screen flickering or blinking. Can you help?
On 6811's over time the contact wires inside of the base of the laptop become loose from their screws from opening and shutting of the laptop. Poor design open the case if you are familiar with computers and take a terminal cleaner and rough up the ends of the contacts then secure them tightly again making sure you gave them enough slack to close the laptop without strain on these wires.

Follow this procedure to troubleshoot an incorrect display on a monitor using the Microsoft® Windows® XP operating system.
IMPORTANT: The procedure below requires a user account with administrator rights.
NOTE: Some monitors must be turned on after the computer is turned on.
Degauss the monitor by turning the monitor off, waiting a few seconds, and then turning the monitor back on.
This may need to be done several times before a degauss is successful.
Some monitors may require up to 20 minutes between degaussings for an optimal effect.
Reset the monitor to factory defaults.
Configure the monitor in VGA Mode.
NOTE: Follow this procedure to reset a Sony® monitor.
Verify the correct monitor resolution is selected in Display Properties.
NOTE: If the monitor is a CRT (Cathode Ray Tube), it may be necessary to adjust the monitor refresh rate to eliminate flicker.
Ensure the color depth is at least High Color 16bit.
Remove any large electrical devices or speakers from the vicinity of the computer.
NOTE: This includes devices plugged into the same power strip as the monitor.
If using a CRT (Cathode Ray Tube) monitor, turn off any fluorescent lighting.
Disconnect and reconnect the monitor to the computer, ensuring there are no bent pins or broken connectors.
If using an available BNC connection for the monitor, ensure the 5 BNC connectors are in the proper order, red, green, blue, horizontal synchronization, and vertical synchronization.
For monitors which support both a BNC and a HD15 connection, ensure the monitor is configured to use the current connection type.
For monitors using both an analog and a digital connection, use only one connection type to the computer.
Wiggle the video cable where it connects to the monitor to ensure the cable does not have a short. If this causes the problem to go away and then come back, the monitor may need to be serviced.
NOTE: If a video pass-through card is used, bypass the video pass-through connection and connect from the monitor directly to the video card. If the problem is resolved the video pass-through connection may need to be replaced. Contact the manufacturer of the video pass-through hardware.
Remove any video extension cables.
Perform a monitor self-test to ensure the monitor is functioning correctly.
NOTE: Follow this procedure to perform a self-test on a Sony® monitor.
Try the monitor in a different room. If successful, suspect an EMI (Electromagnetic Interference) or AC voltage problems in the original room. A line conditioner can be purchased from a local retailer to help resolve voltage problems.
NOTE: A line conditioner is not guaranteed to resolve this issue.
Try the monitor on a different computer.
Perform a system restore to a time when the computer was functioning properly.
Restore the video drivers.

The backlight is probably failing if it is still flickering - does the screen start out pink/red when you turn it on?
The best way to tell is to plug in a known good LCD and verify it lights up properly.
