The OSD is controlled by the video card board (logic board)
It is information stored on the eprom, not something you can just get to. It has to be programmed.

To gain access to the OSD Service Menu from a user service point you normally access it via a series of buttons on the control panel. Holding several buttons at once in a set combination that is particular to that brand, or even that individual series of monitor.

OSD just means "On Screen Display" the menu system and the service menu are the OSD.

My monitor says the OSD is locked I can't unlock it


Hi,

The OSD can be enabled or disabled by pressing and holding the Menu button on the front panel for 10 seconds. If the OSD is locked, the warning message OSD Lock displays for ten seconds.
  • If the OSD is locked, press and hold the Menu button for 10 seconds to unlock the OSD.
  • If the OSD is unlocked, press and hold the Menu button for 10 seconds to lock the OSD

Or else you can try this method also, Hold the menu/ok button for ten seconds, to unlock the OSD. If this doesn't solve the problem, then it's probably the button that got stuck. Remove the casing, locate the menu button's contact switch on the circuit board, and try to release it using something thin like a screwdriver, x-acto knife, or set of plyers.If this doesn't work, chances are the menu button is stuck on a loop, sending a continuous signal to the board (which keeps locking/unlocking the OSD).
If so, your only solution (other than take it to a repair shop) is to remove it, by prying it off with a screwdriver or set of plyers. Of course, you'll lose access to the OSD features, but I guess this is better than to have a message stuck on front of your screen all the time..

Gateway FPD 1830 18.1 in. Flat Panel Problem


Usually in these cases the power supply would be the issue, but you say the OSD window shows up clearly, So the LCD panel is good and the Power Supply /inverter depending on which your FPD has.
FPD 1830 should have 3 boards(logic, Inverter, Power) otherwise just 2(logic, power)

If it is super dim, the problem is the inverter. Or the Power Supply if the inverter is embedded

Otherwise what your issue is the logic board, if you can swap out that part for a good one, Chances are for sure that you will have a spanking new FPD working.

I've worked with these a lot. Im working on one right now.
I hope this helps
Wish you luck
