Question about Acer AL1912B 19" LCD Monitor

1 Answer

17" Acer LCD does not display.

I have a 17" LCD and it does not have a display even when the light is green. When I shine a light directly onto the screen, I am able to view it very faintly. I read on the forums here that the possible problem may be the inverter board (sorry if misspelled). Could it be? And if so how easily are those changed? Does anyone know a monitor repair company in Chicago?

Hi Needtofix, It?s not terribly difficult but you do need some experience handling and working on electronics, tools, a good mechanical aptitude, attention to detail and the willingness to risk doing more harm than good if you make a mistake. The other thing to realize is that you are going to have to invest a couple hours of your time researching, purchasing and installing the components. So if you are willing to spend a couple of hours to save about $100 then it?s worth it. As far as a contractor in Chicago you might try searching this site, but if that fails just look in the phone book for computer repair. I suspect the hard part will be figuring out which one to go to. Let us know how it turns out and if you find a good repair shop you might pass this site on to them so that they can register their services here.

Hi. I just bought a husban fpv x4 dxxxxe h502a. Even with 4 bars of battery the screen on the controller keeps just going black, even though the green led light stays on. Please can you help? Thanks.

Assuming you can still control the thing for flight I assume your complaint is just about the display on the controller for in flight video. This could be a problem localized to just the controller, my most likely bet. A bad display caused by a faulty backlight for the lcd, maybe a bad connection between the inverter for the CCFL backlight could be a likely culprit. Have you dropped the controller? Shine a flashlight onto the screen when you think you should be getting video, have the drone looking at something with high contrast like large black lettering on a white background, where the light shines on the display on the controller do you see the image? This would indicate a bad backlight. You could alway take the controller apart and look for a bad connection, specifically the flat ribbon cable that connects the LCD to the mainboard and the black/red wires between a inverter board to the CCFL backlight that is behind the LCD display.

Or if that sounds like a lot of work, try for a warranty return.

Black display

You say black display. Not sure what you mean. Either the monitor is working or it is not. If you see nothing on the monitor and the power light is yellow, then it is not getting a signal.
If the power light is green and you see nothing, look really closely. You might even shine a flashlight at the monitor to see if there is actually a dim display. If so, the backlight has gone out and needs to be replaced.
I'm assuming that you have tried to brighten the display with the monitor controls.

Green light is on but screen is black

It's either the backlight lamp or backlight inverter is busted due to a power failure or fluctuation. Here's how to determine which is which:
  1. Grab a flashlight.
  2. Turn on the TV.
  3. Shine the flashlight onto the screen.
  4. If you cannot see any display even a faint one, the backlight inverter is dead, else the backlight lamps are busted.
  5. Replace which ever is the culprit.

Princeton VL1715-1 no display

From what you say there is probably not much you can do with it, the parts inside are SMD, to small
to work on. If you could still see txt on the screen when you shine your torch, it could be fixed by
replacing the back lighting PCB.

Hope this helps
Have a nice day.

Wont stay on

IF there is no display even with a flashlight, the P/S board is malfunctioning. Bad capacitors or LCD driver board circuit. Mine did this and it was bad caps, 4 of 8 were bad and a burned out chip on the P/S board.

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.

BenQ FP767 17" Power but no display?

Different faults here.
First fault is no power, it is bad capacitors on the power board.

Second & third faults are the inverters. (power but no image visible, but feint if you shine a light into the screen)
Check the 4 transistors on the main power board for shorts.

If you are unsure what that means, then take it to your local TV technician, he should be able to solve it fairly cheaply.

Hope that helps.
