Ok I have included some information that could be VERY helpful and given the correct credit to the original author. If you find this useful don't forget to rate the thread. Thank you.


SERVICE MODE WARNING:
Without proper documentation Don't mess around with the service mode adjustments unless you know what you're doing and have the service manual to guide you.
Once you enter service mode the first thing you should do is record all the original values BEFORE you change anything! - This is the only way to restore the television to its original (factory default) state should it become necessary to do so.

  • Sit in front the TV, you will need to be able to access keys on the remote and the TV at the same time. Turn the TV "ON"
  • Turn the volume all the way down to 0.
  • Press and hold the TV's front panel volume down button, and then press and hold the remote's "9" button for about a second.
  • The service mode will appear. \ -or-
  • Press "MUTE" on the remote.
  • Press "MUTE" on the remote again, but this time continue to press "MUTE".
  • While still pressing down on "MUTE", press the "MENU" button on the TV front. Release the "MUTE" button. You should now have an S (for service mode) displayed in the upper right corner.
  • Pressing MENU again should bring up the first service option Pressing the Channel Up/Down keys brings up the different service options. Pressing the Volume Up/Down keys changes the associated HEX value.
  • One you have entered the service mode, you can bring up the various test screens by pressing the "TV/VIDEO" button. For example, to minimize screen non-linearities, press the channel down key until PARA appears on the screen, with the associated default value (this is the parabolic adjustment option).
    Then, bring up the cross-hatch pattern by repeated pressing of the TV/VIDEO button. You can then use the volume Up/Down buttons to change the PARA settings, this should cause the grid to bow in (concave) and out (convex). Adjust until the grid is the most linear.
    The numbers 1,2,3,4,5,6 jump to different items. 9 displays SELF CHECK
    The number 7 displays a grid. There's a blinking cursor in the upper left corner. The numbers 2,4,6,8 move the cursor. 3 cycles the colors (RGB), 5 stops the cursor from blinking, then when you push 2,4,6,8, you are adjusting the convergence at that point for the selected color. Pushing 7 again gives you a "warped" grid for a few moments. Pushing 7 again removes the grid from the screen.
    If you're attempting to adjust color or geometry errors, you'll need the Video Essentials DVD, Laser Disc or some other source of test material.

    SOURCE: Toshiba 57LX177: Right side of screen darker than left

    I am not sure...but I have the identical problem. I believe the vertical lines are caused by the inverter board and the darkness is caused by the one of the back lights that needs to be replaced. I am tearing my unit apart now and will find out.

    SOURCE: my flat screen tv is darker on the left side than the right side why?

    Change input device to some other like a DVD player and see. Look for loose contacts in RC jack, cable and socket.

    Switch off TV, switch off power, remove plug and wait for 48 hours and retry.

    If problem persists, call in a qualified service technician.

    If it is an LED LCD TV, the backlight inverter board should be troubleshooted. Contact any service technician.

    I get an intermittent shadow on the left-side of myscreen. Computer works fine, except at times I have the shadow.


    If you mean that the left side of the screen goes darker than the right side, then this is an indication of a faulty backlight. There are probably two CCFL tubes, one on each side of the screen. If one starts to fail, then that side of the screen will get less light and look darker. The tube may need to be replaced.

    Right side of the screen is darker than the left half.


    That is the sign of the power supply output is not at full output, you need to open it up and inspect the caps in the power supply first, look for caps with leaking/bulgin tops.

    Samsung syncmaster 914v monitor problem. right side of display is darker image. can see dots like a newspaper print or looking through a screen. when display is black it almost appears like an image is...


    This is likely the LCD panel itself - you are describing a left/right image error that can be only created by the left/right division by the LCD driver wrapped around the outside of the LCD panel.
    If your monitor uses a separate circuit board to drive the LCD, it could be this driver board.
    Either way, it will require an LCD panel - $$$

    Try clicking the auto adjust button on the screen. If this doesn't work it may be in demo mode, so click the fENGINEbutton on the monitor and make sure it is selected on the normal setting.

    Printing okay on left side but gets darker and blurrier towards right side of lines


    Remove the toner cartridge and drum assembly together. Gently rock the assembly from end to end, as when installing a new toner cartridge. Then put the assembly back in place. This procedure worked for me. I'm guessing that I must have laid the toner and/or drum on its side, or perhaps upside down, when I was replacing the drum, and this was responsible for the problem.
