Question about Acer AL1912 19" LCD Monitor

1 Answer

Menu keeps popping up

I hope you can help! This monitor is less than 3 years old and a few weeks ago the menu for the monitor started popping up. I can't use the controls on the monitor to make it go away. I've tried unplugging, turning off and on, etc.

Sometimes it will stay on there for a long time, other times it will just pop up and then go away. The contrast bar is at 0 and I can't fix it

It just popped up again so I can't see what I had just typed. The contrast keeps flashing and the exit symbol keeps hightlighting (now it went away again). I've tried troubleshooting, but no effect.

Re: menu keeps popping up

Never a good idea to clean with any spray cleaner. The cleaner does get down in the button bar and cause corrosion and shorting along ribbon cable. Use screen wipes for computer monitors only on TV's and any type of monitors. You can remove the back of the case. And remove the button board and clean with a cue tip and alcohol along ribbon cable.

I bought a SyncMaster 2333 monitor 1 and half year ago. Suddenly, my monitor does not show anything. Turn on/off switch is not working. Sometimes it shows just bluescreen. I am wondering what is wrong and...


This problem usually indicates a failure of the power supply board that runs the video control board. You can fix it but if your unit is only 1.5 years old then its still under warranty, 3 years parts and labor. Go to and go to the service section to start a warranty claim. It takes about 2 weeks to go out and back to you.

Viewsonic VX2035WM monitor buttons no longer working

Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed VIEWSONIC and ALL monitors to get some ideas what goes wrong:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My 15 inch Dell LCD flat screen monitor has 4 blue (cyan) verticle pixel bands about half an inch wide on my screen. The monitor is about 3 or 4 years old. Can you help?

Sorry, but it's kaput. Broken. LCDs were pretty bad a few years ago. A new one will cost a lot less than that one did, and will work a lot longer.

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. Look in our monitor repair section for step by step repair guide for this model. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

Config screen keeps popping up

A friend of mine had the exact same same problem. I think I fixed it, because it has been 2 hours, without the menu popping up. You need to open the monitor:

- Place it face-down on a flat surface
- Remove the cover of the hinge by gripping it with both hands and gently squeezing and pulling.
- Undo the 4 screws and remove the stand (base)
- Undo the four screws tha hold the cover down (4 corners)
- Use a flat screwdriver to seperate the 2 halves (I used 2, a small one to lift the back, a bigger one for leverage)

You will see a small PCB, fastened by 3 screws, at the bottom (where your menu+on/off buttons are) with a ribbon connection to the screen. Next:

- Unscrew the PCB, and gently lift it out.
- Clean the microswitches and the ribbon cable connection.
- Reassemble the monitor.

To clean microswitches and the connection, I used Kontakt Video 90 spray. There must be sprays on the market where you are. It's basically an alcohol-based cleaning spray. Good for cleaning video/tape/floppy heads, CD/DVD lenses, memory modules, etc.

Good luck!

Brightness pops up

it may just be stuck , if you push the button does it click like the others, a little wd40 around the button , lightly, may unstick it.
or you have to take the bezel off and see if the positioning is the issue.

Problem on hp monitor

I know you said there were others that had the same problem with the Main Menu coming up and I thought I would tell you what I did to fix the problem.

1. I shut down the PC.
2. I removed the power cable and video cable from the back of the monitor.
3. I removed the four screws that hold the stand for the monitor and slid the stand off.
4. I then removed the 5 screws that hold the back cover on the monitor.
5. I took two flat blade screw drivers and carefully removed the back cover.

At the bottom of the monitor case, there is a small circuit board the holds the 6 switches for controlling the display.

6. I located the button that calls up the Main Menu. It is the second switch from the left as you are looking at the monitor from the rear.
7. I used a small solder iron and heated up the four prongs in sequence while holding the switch with a pair of needle nose pliers. I had to rotate this process from one prong to the other while all the time applying slight pulling pressure on the switch pulling it away from the circuit board.
8. Once the switch was removed, I put the cover back on and tightened up the five screws.
9. Then I slid the base back in the slot it came from and tightened the four screws.
10. I connected the video and power cable and turned on the PC.

With the switch removed the Main Menu never popped up again and I am so very happy.
