It sounds like a backlight or inverter problem. You can verify this by using a bright light to shine on the screen surface. If you can see the picture (but it will be very dark) that means that the backlight which illuminates the screen from behind. You would have to replace the inverter to test it, but there is good news: These are pretty difficult to find parts for, and not an easy repair for an amateur; acer products usually have a 3 year warranty on the backlight/inverter system, so I would start there.

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

Check your connections to the PC. Make sure that they are nice and secure. If there is a resolution problem setting it should display the boot process and then go blank after starting the operating system.

My acer al1916w displays the image for 3 seconds then goes black


Sounds like your video card. Check to make sure it's connected properly. If so, check to make sure it's properly seated to *********** board. The possible issue could be the card is connected enough to display the picture, but not enough to communicate with the monitor to stay on because it has an active feed. Best of luck fixing it

I have connected my old dell laptop to this TV with VGA cable and audio cable and it worked with no problem. Have new Acer Aspire one netbook- connected to computer with same cables - can see windows...


First, you want to make sure the laptop's internal/external display mode is set properly. On Acer netbooks, this is usually changed by holding the "Fn" key, and pressing "F5". Either the TV or the computer display should flicker when you do this. There are 3 modes:

1 Computer only
2 TV Only
3 Computer and TV

If changing between thos emodes doens't work, continue on.


I am going to assume you are running Windows XP. Please correct me if I am wrong.

To display your desktop on an external monitor, you'll need to change/check some settings. Your netbook is most likely attempting to set it's display settings automatically, but it is expecting a computer display, not a television, so the resolutions and refresh rates are conflicting. That's why it will only display on one and not the other. Before Windows loads, the netbook is using a very low resolution,so it displays on the TV. Once Windows loads, it switches to some non-standard resolution that your TV cannot display and defaults back to your netbook screen.

The solution is to find a resolution that your television will display:

1.Right-click the desktop, and then click Properties.

2.In the DisplayProperties dialog box, click the Settings tab.

3.Click the Display list and select your external monitor (..the TV. It will most likely be display #2).

4.Select the Extend my Windows desktop onto this monitor option.

5.Select 640x480 in the "Screen Reolution" section for Display #2.

6.Click Apply or OK.

Note: If you see the background change on your television, mmove your mous there to make sure it's working. If it DOES work, go back to the "Screen resolution" section for Display #2 and find the highest resolution your television will display
