Hello. I know its not exactly technical problem, but my younger sister changed absolutely contrast and brightness settings on my LG Flatron LCD L1752S, and there is no default button, can you tell me what is the default settings ? Thank you

Dear amy mcioynt,

Welcome, and thank you for using FixYa!

The issue you describe it caused by the video board going bad. All of the controls for video display, clocking, brightness, contrast, and input source is handled by this card.
They are replaceable, if you have the part number. Most of the time they range from $50 - $75

Have a great evening!

On screen menu should have brightness and contrast, and other adjustment.
You can get user manual here:

see if there is some software cd with it or see if display properties has somthing in setup

1. clean the G4 wire.

2. change the neck base.

3. adjust the focus preset in LOT .

The supplied software should allow you to set brightness and contrast if there are no front panel buttons to set it.
Check for LG or Flatron programs under the Programs listing available from the Start panel.

there is sometimes a subtle change in highlight when you have selected the brightness (or any manual change menu selection) you should then be able to make changes to the selection via the up or down buttons on the monitor

on the front of the monitor there are key buttons naming menu, ok button and left & right arrow marks buttons first press menu button then go to brightness then by using arrow keys you can increase & decrease the brightness once you are finished decreasing r increasing press ok button.& there are many other settings you can change like contrast etc....

I fixed it myself, it seems that the monitor have some problems remembering it's settings and sometimes it automatically set its settings to crazy values that are out of the range that we are allowed to input. For my case, the setting that was crazy was the gamma setting since it was set so high. I wasn't able to bring it back to a normal setting so I found a way to do it by resetting the monitor. So to reset these display settings such as colour, contrast, brightness and gama, you need to turn on the monitor and unplug the monitor without turning it off and plug it back in again. It will automatically power on and the correct default settings will be present.

This forum isn't very helpful is it?
