Question about Acer AL1912 19" LCD Monitor

1 Answer

Config screen 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

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!

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.

Lock/unlock symbol appears in the middle of the screen


5-22-09 Same problem last month. I had the problem a year ago for a month, then it stopped, reappearing this last month. Last week, I finally called support...I was accidentally transferred to a Dell "internal" technical support department...happily a very diligent technician spent a bit of time with me for free...for same problem, even though he confirmed I was over a year past all warranties. He confirmed this was a monitor problem (not virus, malware, etc.). He also confirmed their standard "guidance"/solution for this monitor issue (if under warrantee) is to replace the monitor (i.e. not attempt to fix it). New monitor needed. But problem again gone for last 10 days. So, when fully irritated, buy new monitor.

hi,

It is possible that menu button on the monitor is stuck. I suggest to call your computer manufacturer where you purchased the monitor, check for the warranty and request for a replacement.

Keep me posted.

Thanks

The Contrast screen pops on all the time


It looks like your UP button contact is demaged.
SOLUTION is to insert a piece from your business card mostly above the button to adjust it down or up. It works fine.

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.
