SOURCE: Acer AL1916W 19" problem

Hello mat78, Unfortunatelly the problem is hardware based. You will need to have the monitor repaired in a service center. Here's why: LCD/TFT monitors don't produce light themselves. They are composed by a matrix of transistors (TFT - thin film transistor) that have the property to reflect or allow some light (certain wavelenghts)to pass through them. They don't produce light by themselves. Instead there is a fluorescent tube (neon like) light inside the monitor and that's the light source used in order for you to see what's on the screen. A flourescent light is suposed to last pretty much, i don't think yours has a problem, you say it works for some seconds or so. Instead your problem is most probable with the inverter circuitry that powers on that light. It's a common problem among these types of monitors but in your situation i don't think it will be an expensive repair. In the case that the screen is dark (in a dark place you can't read or view anything on it) but if you apply light to it ( a flashlight or something) and you see something, then the problem is most likely to have occured with the invertor. Try to ask at a local service center for a repair, this shouldn't be an expensive procedure. Hope this helps.

By initiating the on screen menu, you navigate to the brihghtness etc.This can also be related to contrast. Get a keyboard with zoom keys that will make it east to enlarge text.Mine is a logitech wireless S510 and its a great bargain and comes with mouse.the best solution is, however to buy a 42 inch or larger display and use that as you monitor. I can never go back!

SOURCE: Acer AL1912 19" LCD Monitor goes black after power up.

I had a similar problem I had two of these monitors UK spec completely dead and on dissasembly there were two capacitors on the power board which had clearly blown - their 'roofs' were bulging. These were 1000uF 16v radial electroltics - a similar repair to the above cost £5 (say $10) inc P&P to get replacements for both monitors and both work fine now.

SOURCE: monitor goes black after a few seconds

1) It could be your power supply is going bad or not strong enough to keep the monitor on.
2) It could be a memory issue. Video is one of the signs that your ram is bad.
3) It could be a loose connection or the monitor itself.
I would suggest first unplugging all the connections to the monitor and pc then plug in again and restart. If it still turns off try a monitor that you know works. If you still have the problem try changing your memory sticks. It's unusual that it would be a video card/ on board video because it usually either works or it doesn't.

SOURCE: power supply on 17" acer monitor

franh, Typical of a lcd/fpd monitor! There is nothing you or hundreds of others can do to repair it all by yourself. I have repaired 3 monitors and helped tutor 2 others on fixya with their monitors. All had same exact symptom as your monitor. I need you to do a simple test for me. With failed Acer monitor near to your Fully Booted PC with a known good desktop being displayed on back-up monitor, quickly swap out the monitor cables from the back of the PC. Keep touching the CTRL key on you keyboarb every 30-50 seconds to keep the PC from sending out sleep mode command to monitor while doing the reconnect of acer to your PC monitor output port. Make sure the Acer also is connected to a live wall outlet/power strip. Turn on the Acer and note what happens. If screen shows a sharp clear image for a second, then goes black, do the following. Get a bright flashlight and shine it on the screen from a distance of 1 or 2 inches and tell me if you can see the desktop display. get back to me with your observations. I'm louie12fix on fixya or lmistyrel@ aol.com.

ViewSonic 19" flat screen monitor goes black - intermittently


Hi,
There could be a problem with your display card settings or the display card itself. If you are using Windows operating system, make sure that you have the monitor driver installed for that specific monitor. This is to ensure that Windows only allows settings for which your particular monitor was designed.
Let me know if I can assist you any further regarding this.
Best wishes,
Graemevm

Monitor screen goes out (black) 2 seconds after turning on


Your site is extremely misleading and fraudulent. I was under the impression that I would at least get a hint at what might be a problem instead of you folks making me wait to get a money for something answer that you could have displayed on your main page. Places like yours have no place on the internet and I'm going to find out what I can do to report you.

Thank's for nothing

You need to try another monitor, any type. If you find another monitor does functions return the 19" monitor. Most monitors come with a 1 year warranty.

Black screen


Your backlight is starting to go bad! These backlights are little tiny florecent bulbs, these can be replaced and they do burn out. Sounds like your back light is bad! Could be costly to replace as there are not too many places out there that will replace the bulbs.
