Question about Sceptre X9G Komodo IV 19" Flat Panel LCD Monitor

Gateway LCD powers on but has no picture

I have a Gateway FPD1730 LCD monitor. When I plug it into my Gateway 500x desktop the power light turns green and then says "Power Saving Mode" and then it goes black. It will occasionally flash on and have a picture and then go off. When I unplug the VGA cord the monitor says "No signal found". I know the screen is working because is shows the picture and it's fine.

I initially though it was the video card so I switched it out. I was running an NVIDIA 128mb AGP video card and I replaced it with an extra I had. I am now running an ATI 128mb AGP card. I then came to realise that it wasn't the video card at all. I connected my Dell CRT test monitor with the old video card and it works without a problem.

What can I do to fix the monitor? I would really prefer to not have to buy a new one. It seems like a semi-simple fix because I can see the picture on occasion.

Thanks in advance!

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?


The factory reset is in the on screen menu, the Auto set button is for syncronizing the signals to the PC video incase it went out of sync.

I have a FPD 1830 flat screen monitor not displaying picture


Send the monitor. It's a power supply problem. My 15.4" LCD has the problem, too, whenever I move the monitor down, it powers off, and the menu disappears as well, but I'm going to fix the screen.

LCD monitor goes blank


It appears that the display resolution set in your display properties is out of the range that the LCD can display.

Try this.

Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)

Green Light, no Display - Gateway FPD1730


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.
