I own a Gateway FPD1730 LCD monitor. I am curious to know if the External button on the monitor that's called AUTO/SET is a RESET button for the factory settings?

Gateway Monitor Repair Complete

At the bottom of the monitor, there are some buttons. Pushing the right-most button (Auto/Set) will enable the automatic configuration to happen. This will "automatically optimize the monitor's image position, clock, and phase."

I have a smaller sized Gateway monitor than yours, but I'm sure the monitor buttons (on the front) perform the same functions on all sizes.

You should have eight control buttons on the front of the bezel (as listed from left to right): source, menu, down arrow, up arrow, left arrow, right arrow, auto/set, and on/off buttons.

Press the menu button, the first dialog screen that appears (at least on mine) is the brightness/contrast function. The screen will show the function to be changed, and a very small picture of what screen you have in view.

Once the first function is listed on the screen, press the down arrow to access the other screens (color, tracking and set-up), each having their own little picture indicating what screen you are looking at.

Brightness/contrast - picture of half light, half dark circle
color - RGB picture
tracking - two squares on top on one another slightly off center
set-up- hand pointing left

You want the set-up screen which shows a picture (I think) of a little hand pointing to the left. Once you are in the set-up screen, press the auto/set button and the first line will be highlighted (usually it is the language choice).

Once highlighted, press the right arrow button until your language name appears (i.e., English, Duetsch, Francais, Espanol Italiano, -there is no choice on mine for Japanese, etc.).

Press the menu button again and that should do it.

this a micro-controller issue and a tech need to replace components that regulate the voltage to the florescent tube that excite the LCD to give a picture. they are sometimes call a LCD controller. This is a main board problem.

press the menu button on screen panel and press exit.

To solve your problem you can go to any rad shack or electronics store and pick up a DVI-AVG adapter. The're about $14.00.

tell me in detail the exact problem...i can solve it

Try using it on a different computer, it's possible that it is your graphics card causing the problem. Check for bent pins.

I picked up a FPD1730 monitor for free which was just sitting out in my apartment hallway. I suspected something was wrong and sure e**ugh there was ** backlight, but I could see faint video when I shined a flashlight on it.

A quick Google search of the inverter model # led me to a German forum which suggested replacing the fuse labeled "F1" on the inverter board. I don't have a matching fuse on hand but I bridged the connection with a wire and sure e**ugh the backlight came back on. Short-circuiting like this is definitely **t 100% safe but if you can find a 4A fuse then it's a really cheap and quick fix.
