Hi,

Based on your description, the problem could either be:

  • CCF (cold cathode florescent) lamp; and/or
  • inverter.
Since the Acer AL1512 works fine except dark, we can rule out the video interface, power supply and ontroller. Again, the display showing (even dimly) is significant, it tells us that the components are working except that for some reason and most likely it is heat related. Possibly a cold solder, a loose connection and/or a dried up capacitor. You could actually verify this be shining a flashlight diagonally across the screen and some semblance of the desktop albeit dark would be slightly visible.

What is required is opening the LCD lid/panel to perform repairs. This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

How to repair no power ilpi-011e131175


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.

Acer lcd screen p191w makes a buzzing noise when turning on and the screen is very dim. then it shuts off. can this be fixed at home


Not safely and not unless you are confident and competent with electronics. I would put the dimming down to a failing display circuit, but the buzzing sounds as though a short is developing. I would take it to a tv repair shop who can advise better and maybe replace or repair the components

Dear sir, my lcd monitor 17"


> after getting Internet connection of my PC, that trouble came.

That probably has _NO_ affect on your LCD monitor.

You could either:
* live with the problem, spending NO money
* spend $50 to $75 for a TV/audio/video technician to try to fix it
* spend $50 to $75 to buy a used 17" LCD monitor
* spend $100 to $150 to buy a new 19" LCD monitor

Acer AL175 TFT monitor is coming on but its very dim


The screen itself is starting to go bad which is why your having to turn up the brightness to 100% just to see something. Replacing the screen would cost more then the whole lcd monitor itself so its best to get a new one.
